Reconstruction of physical parameter distributions underlying the available geophysical data sets usually requires the use of tomographic reconstruction techniques. To improve the quality of the obtained models, the information content of all data sets should be considered during the model generation process, e.g., by employing joint or cooperative inversion approaches. Here, we extend the zonal cooperative inversion methodology based on fuzzy c-means cluster analysis and conventional single-input data set inversion algorithms for the cooperative inversion of data sets with partially co-located model areas. This is done by considering recent developments in fuzzy c-means cluster analysis. Additionally, we show how supplementary a priori information can be incorporated in an automated fashion into the zonal cooperative inversion approach to further constrain the inversion. The only requirement is that this a priori information can be expressed numerically; e.g., by physical parameters or indicator variables. We demonstrate the applicability of the modified zonal cooperative inversion approach using synthetic and field data examples. In these examples, we cooperatively invert S- and P-wave traveltime data sets with partially co-located model areas using water saturation information expressed by indicator variables as additional a priori information. The approach results in a zoned multi-parameter model, which is consistent with all available information given to the zonal cooperative inversion and outlines the major subsurface units. In our field example, we further compare the obtained zonal model to sparsely available borehole and direct-push logs. This comparison provides further confidence in our zonal cooperative inversion model because the borehole and direct-push logs indicate a similar zonation.}, language = {en} } @article{KroenerWildeZhaoetal.2006, author = {Kr{\"o}ner, Alfred and Wilde, Simon A. and Zhao, Guochun and O'Brien, Patrick J. and Sun, Min and Liu, Dun Yi and Wan, Yusheng and Liu, S.

SHRIMP ages for magmatic zircons from two dykes reflect the time of dyke emplacement at similar to 1915 Ma, whereas metamorphic zircons dated by both SHRIMP and evaporation techniques are consistently in the range 1848-1888 Ma. The Youngest granitoid gneiss yet dated in the Hengshan has an emplacement age of 18 2 17 Ma. These results complement recent geochronological studies from the neighbouring Wutai and Fuping Complexes, to the SE of the Hengshan, showing that a crustal extension event Occurred in the late Palaeoproterozoic. This preceded a major high-pressure collision- type metamorphic event in the central part of the North China Craton that occurred in the Palaeoproterozoic and not in the late Archaean as previously thought. Our data support recent suggestions that the North China Craton experienced a major, craton-wide orogenic event in the late Palaeoproterozoic after which it became cratonized and acted as a stable block.}, language = {en} } @article{KroenerAlexeievKovachetal.2017, author = {Kr{\"o}ner, A. and Alexeiev, D.

Early Precambrian rocks were previously reported from several metamorphic complexes in the Kyrgyz Tianshan orogenic belt, mainly based on multigrain conventional zircon dating, but the present study only confirmed such rocks at one site, namely in the Kuilyu Complex of eastern Kyrgyzstan. New single grain SHRIMP II zircon ages, geochemical data, and whole-rock Nd isotopic compositions for granitoid gneisses of the Kuilyu Complex elucidate the age, origin and tectonic settings of this oldest continental fragment in the Tianshan. The Kuilyu Complex is part of the basement in the Ishim - Middle Tianshan microcontinent. It consist of a strongly deformed and metamorphosed supracrustal assemblage of paragneisses and schists which are tectonically interlayered with amphibolites, migmatites and granitoid gneisses. Our zircon dating indicates that the Kuilyu Complex contains two suites of Palaeoproterozoic granitoid gneisses with magmatic protolith ages of ca. 2.32-2.33 Ga and 1.85 Ga. Granitoid magmatism at 1.85 Ga was almost immediately followed by amphibolite-facies metamorphism at ca 1.83 Ga, evidenced by growth of metamorphic zircon rims. The older, ca 2.3 Ga granitoid gneisses chemically correspond to calc-alkaline, metaluminous, I-type magnesian quartz diorite and granodiorite. The protolith of the younger, ca. 1.85 Ga granite-gneiss is an alkalic-calcic, metaluminous to peraluminous, ferroan medium-grained porphyric granite with chemical features resembling A-type granites. The 2.3 Ga and 1.85 Ga granitoid gneisses have slightly to distinctly negative initial epsilon(Nd) values of -1.2 and -6.6, and similar depleted mantle Nd model ages of 2.7-2.6 Ga, which imply melting of Neoarchaean continental crust. The zircon age patterns of the Kuilyu Complex resemble those of exposed rocks in the Tarim Craton, where episodes of granitoid magmatism at ca. 2.3-2.4 and 1.85 Ga, followed by amphibolite-facies metamorphism at ca 1.85 Ga, are also recorded. Similarities in the early Precambrian magmatic and metamorphic episodes as well as similar histories during the Neoproterozoic and early Palaeozoic suggest that the Ishim-Middle Tianshan microcontinent was rifted off the Tarim Craton. Similar age patterns also suggest possible tectonic links of the Kuilyu and Tarim continental blocks with the Baidrag Block of central Mongolia. In contrast, substantial differences in age and Precambrian evolution between the Anrakhai block of southern Kazakhstan and the Kuilyu Complex argue against a previous connection and suggest the former to represent an independent continental terrane. Current data show that early Precambrian rocks in the western CAOB outside Tarim only occur at two sites, namely in the Anrakhai Complex of southern Kazakhstan and in the Kuilyu Complex of eastern Kyrgyzstan.
