T1 - Geochemistry and geochronology of the Guajira Eclogites, northern Colombia evidence of a metamorphosed primitive Cretaceous Caribbean Island-arc JF - Geologica acta N2 - The chemical composition of eclogites, found as boulders in a Tertiary conglomerate from the Guajira Peninsula, Colombia suggests that these rocks are mainly metamorphosed basaltic andesites. They are depleted in LILE elements compared to MORB, have a negative Nb-anomaly and flat to enriched REE patterns, suggesting that their protoliths evolved in a subduction related tectonic setting. They show island-arc affinities and are similar to primitive island-arc rocks described in the Caribbean. The geochemical characteristics are comparable to low-grade greenschists from the nearby Etpana Terrane, which are interpreted as part of a Cretaceous intra-oceanic arc. These data support evidence that the eclogites and the Etpana terrane rocks formed from the same volcano-sedimentary sequence. Part of this sequence was accreted onto the margin and another was incorporated into the subduction channel and metamorphosed at eclogite facies conditions. Ar-40-Ar-39 ages of 79.2 +/- 1.1Ma and 82.2 +/- 2.5Ma determined on white micas, separated from two eclogite samples, are interpreted to be related to the cooling of the main metamorphic event. The formation of a common volcano-sedimentary protolith and subsequent metamorphism of these units record the ongoing Late Cretaceous continental subduction of the South American margin within the Caribbean intra-oceanic arc subduction zone. This gave way to an arc-continent collision between the Caribbean and the South American plates, where this sequence was exhumed after the Campanian.

The first three genera belong to the family Rhapydioninidae, while the fourth is placed in the family Alveolinidae. Two species, Praechubbina breviclaustra and P. oxchucensis sp. nov., represent the primitive genus Praechubbina, while the species cardenasensis and obesa, previously ascribed to this genus, must be reassigned respectively to Chubbinella gen. nov. and Caribalveolina. The species Chubbina jamaicensis, C. macgillavryi and C. fourcadei sp. nov. complete the inventory of Chubbina. The alveolinid genus Caribalveolina comprises two species, C. obesa and C. michaudi. Caribbean alveolinaceans include two successive assemblages. The lower assemblage is characterized by Praechubbina oxchucensis, P. brevisclaustra, Chubbinella cardenasensis and Caribalveolina obesa. The upper assemblage is represented by the genus Chubbina, with C. fourcadei, C. jamaicensis and C. macgillavryi, and Caribalveolina michaudi. The age of the lower assemblage is uncertain (probably Late CampanianEarly Maastrichtian), while the upper assemblage has been dated by strontium isotope stratigraphy as Late Maastrichtian.

Responding to an influential view shaping this debate, that Glissant’s work can be categorised into an early political and late apolitical phase, this dissertation claims that this division is based on a narrow conception of 'engaged political writing' that prevents a more comprehensive view of the changing political strategies Glissant pursued throughout his life from emerging. Proceeding from this conceptual basis, the dissertation is concerned with re-reading the dimensions of Glissant's work that have hitherto been relegated as apolitical, literary or poetic, with the aim of conceptualising the politics of relation as an integral part of his overall poetic project. In methodological terms, the dissertation therefore proposes a relational reading of Glissant’s life-work across literary genres, epochs, as well as the conventional divisions between political thought, writing and activism. This perspective is informed by Glissant's philosophy of relation, and draws on a conception of political practice that includes both explicit engagements with established political systems and institutions, as well as literary and cultural interventions geared towards their transformation and the creation of alternatives to them. Theoretically the work thus combines a poststructuralist lens on the conceptual difference between 'politics' and 'the political' with arguments for an inherent political quality of literature, and perspectives from the Afro-Caribbean radical tradition, in which writers and intellectuals have historically sought to combine discursive interventions with organisational actions. Applying this theoretical angle to the analysis of Glissant's politics of relation results in an interdisciplinary research framework designed to explore the synergies between postcolonial political and literary studies. In order to comprehensively describe Glissant's politics of relation without recourse to evolutionary or digressive models, the concept of an intellectual marronage is proposed as a framework to map the strategies making up Glissant's political archive. Drawing on a variety of historic, political theoretical and literary sources, intellectual marronage is understood as a mode of radical resistance to the neocolonial subjugation for which the plantation system stands historically and metaphorically, as an inherently innovative political practice invested in the creation of communities marked by relational ontologies, and as a commitment to fostering an imagination of the world and the human that differs fundamentally from the Enlightenment paradigm. This specific conception of intellectual marronage forms the basis on which three key strategies that consistently shape Glissant's political practice are identified and mapped. They revolve around Glissant's engagement with history (chapter 2), his commitment to fostering an imagination of the Tout-Monde (whole-world) as a political point of reference (chapter 3), and the continuous exploration of alternative forms of community on the levels of the island, the archipelago and the Tout-Monde (chapter 4). Together these strategies constitute Glissant's personal politics of relation. Its abstract characteristics can be put in a productive conversation with related theoretical traditions invested in exploring the political potentials of fugitivity (chapters 5), as well as with the work of other postcolonial actors whose holistic practice warrants to be described as a politics of relation (chapter 6). N2 - Diese Dissertation befasst sich mit der politischen Dimension des Werks von Édouard Glissant (1928-2011), der zu den einflussreichsten aus der frankophonen Karibik stammenden postkolonialen Theoretiker*innen gezählt wird. Durch eine Kombination von literatur- und politikwissenschaftlichen Ansätzen wird Glissants Werk als Ganzes studiert und auf seine politischen Potenziale geprüft. Kennzeichnend für den verfolgten Rechercheansatz ist ein weites Verständnis des Politischen, das sich von gängigen Vorstellungen der Auseinandersetzung mit politischen Systemen und Machtkämpfen unterscheidet, in dem es literarischer und kultureller Arbeit dezidiert politische Bedeutung zuschreibt. Das Konzept der Politik der Relation aufgreifend, welches in Glissants späteren Schriften erscheint, befasst sich diese Arbeit mit den Fragen, was ist die Politik der Relation? Wie kann sie beschrieben werden? Und welche Verbindungen lassen sich zwischen ihr und verwandten politischen Praktiken nachzeichnen? Die Forschungsarbeit kommt dabei zu dem Ergebnis, dass mit der Politik der Relation sowohl die diversen politischen Praktiken beschrieben werden können, die das Werk Glissants durchziehen, als auch außerhalb dieses Bereichs postkoloniale politische Praktiken analysiert werden können. Im erstgenannten Kontext bezieht sich der Begriff auf eine ganzheitliche und vielschichtige Praxis eines Dichters und Intellektuellen, dessen politisches Engagement in erster Linie auf Veränderungen im Bereich des Imaginären und der Erschaffung alternativer Gemeinschaften abzielte, der jedoch darüber hinaus wiederholt diskursiv und organisatorisch in bestehende Institutionen und Gemeinschaften intervenierte, um Relationen herzustellen, die von bestehenden Diskursen und politischen Strukturen unterbunden wurden. Im zweiten Kontext, also außerhalb von Glissants eigenem politischen Denken und Handeln, wird die Politik der Relation zudem als ein Begriff vorgeschlagen, der die Praxis bestimmter postkolonialer Akteure beschreiben kann, deren Handeln jeweils ein ganzheitlicher Anspruch zugrunde liegt, bei dem Leben und Schreiben, Inhalt und Form, Mittel und Zwecke nicht voneinander getrennt werden können. Ihre politische Praxis orientiert sich an der radikalen Diversität und Vernetzung aller Kulturen der Welt, sie schöpft aus ihr Kraft und strebt an, sie zu beschützen. Indem die Dissertation Verbindungen zwischen diesen beiden Ebenen aufzeigt, ist sie methodisch ebenfalls relational angelegt.

The evolution of satellite gravimetry and altimetry techniques allows testing 3-D density models of the lithosphere, taking advantage of the high spatial resolution and homogeneous coverage of satellites. However, it is not trivial to discretise the source of the gravity field at different depths. Here, we propose a new method for inferring tectonic boundaries at the crustal level. As a novelty, instead of modeling the gravity anomalies and assuming a flat Earth approximation, we model the vertical gravity gradients (VGG) in spherical coordinates, which are especially sensitive to density contrasts in the upper layers of the Earth. To validate the methodology, the complex oceanic domain of the Caribbean region is studied, which includes different crustal domains with a tectonic history since Late Jurassic time. After defining a lithospheric starting model constrained by up-to-date geophysical data sets, we tested several a-priory density distributions and selected the model with the minimum misfits with respect to the VGG calculated from the EIGEN-6C4 data set. Additionally, the density of the crystalline crust was inferred by inverting the VGG field. Our methodology enabled us not only to refine, confirm, and/or propose tectonic boundaries in the study area but also to identify a new anomalous buoyant body, located in the South Lesser Antilles subduction zone, and high-density bodies along the Greater, Lesser, and Leeward Antilles forearcs.

The paper provides for an analysis of the facts behind the CARICOM claim and asks whether the law of state responsibility is able to provide for the demanded compensation. As the intertemporal principle generally prohibits retroactive application of today’s international rules, the paper argues that the complete claim must be based on the law of state responsibility governing in the time of the respective conduct. An inquiry into the history of primary (prohibition of slavery and genocide) as well as secondary rules of State responsibility reveals that both sets of rules were underdeveloped or non-existent at the times of slavery and alleged (native) genocides. Therefore, the author concludes that the CARICOM claim is legally flawed but nevertheless worth the attention as it once again exposes imperial and colonial injustices of the past and their legitimization by historical international law and international/natural lawyers.

Throughout their talk, Bala and Kerrigan engage with the legacy of Haitian anthropologist Michel-Rolph Trouillot. Specifically, they focus on his approach of looking from small units, such as small villages in Dominica, outwards to larger political structures such as global capitalism, social inequalities and the distribution of power. They also share insights from their own research on embodied practices in the Caribbean, Europe and India and answer questions such as: What can research on and through embodied practices tell us about systems of power and domination that move between the local and the global? How can performance practices which are informed by multiple locations and cultures be read and appreciated adequately? Sharing insights from his research into Guyanese prisons, Kerrigan outlines how he aims to connect everyday experiences and struggles of Caribbean people to trans-historical and transnational processes such as racial capitalism and post/coloniality. Furthermore, he elaborates on how he uses performance practices such as spoken word poetry and data verbalisation to connect with systematically excluded groups. Bala challenges naïve notions about the inherent transformative potential of performance in her research on performance and translation. She points to the way in which performance and its reception is always already inscribed in what she calls global or planetary asymmetries. At the conclusion of this conversation, they broach the question: are small places truly as small as they seem? N2 - “Embodied Practices – Looking From Small Places” ist das editierte Transkript eines Gesprächs zwischen der Theaterwissenschaftlerin Sruti Bala (Universität Amsterdam) und dem Soziologen und Kriminologen Dylan Kerrigan (University Leicester), welches als Online-Veranstaltung unter gleichem Titel im November 2020 stattfand. Zentraler Ausgangspunkt des Gesprächs ist die Auseinandersetzung mit dem Werk des haitianischen Anthropologen Michel-Rolph Trouillot und insbesondere seinem Ansatz ausgehend von kleinen Einheiten, wie etwa kleinen Dörfern auf Dominica, auf große politische Zusammenhänge zu schauen, wie die Weltwirtschaft oder aber auch die Verteilung von Macht und sozialen Ungleichheiten. Davon ausgehend, geben die beiden Wissenschaftler*innen Einblicke in ihre eigenen Forschungen zu verkörperten, performativen Praktiken in der Karibik, in Europa oder in Indien. Sie verhandeln Fragen wie etwa: Wie kann Forschung zu und mit performativen Praktiken unser Verständnis von Macht- und Herrschaftssystemen schärfen, die gleichzeitig lokal und global wirksam sind? Wie könnte eine angemessene und wertschätzende Auseinandersetzung mit performativen Praktiken aussehen, die sich aus unterschiedlichen geografischen und kulturellen Kontexten speisen? Kerrigan führt aus wie er in seiner Forschung zeigt, dass alltägliche Erfahrungen und Kämpfe in der Karibik nicht außerhalb von historischen und transnationalen Prozessen wie racial capitalism sowie Post/Kolonialität zu denken sind. Darüber hinaus berichtet er, wie er performative Praktiken wie spoken word oder data verbalisation einsetzt, um mit systematisch marginalisierten Personen in Kontakt zu treten. Bala legt dar, dass sie in ihrer Forschung, beispielsweise zu Performance und Übersetzung, darum bemüht ist, naive Vorstellungen von dem scheinbar inhärent transformativen Potential von Performance zu dekonstruieren. Aufführungen und deren Rezeption seien vielmehr immer schon eingeschrieben in das, was Bala globale oder planetarische Asymmetrien nennt. Schließlich verhandeln sie die Frage wie klein sogenannte “kleine Orte” tatsächlich sind.
