A common problem in ecology is identifying the relationship between relief and site properties obtainable only by point measurements. The method of Multi-Scale Landscape Analysis (MSLA) identifies such correlations. MSLA combines frequency filtering of the digital elevation model (DEM) with an estimation of the optimum filter coefficients using an optimization procedure. Tested using point data of soil decarbonation from a German young moraine landscape, MSLA provided significant results. Implemented within open source software SAMT. MSLA is comfortable and flexible to use, offering applications for numerous other spatial analysis problems.
This study monitors regional changes in the crystallinity of carbonaceous matter (CM) by applying Micro-Raman spectroscopy to a total of 214 metasediment samples (largely so-called Bundnerschiefer) dominantly metamorphosed under blueschist- to amphibolite-facies conditions. They were collected within the northeastern margin of the Lepontine dome and easterly adjacent areas of the Swiss Central Alps. Three-dimensional mapping of isotemperature contours in map and profile views shows that the isotemperature contours associated with the Miocene Barrow-type Lepontine metamorphic event cut across refolded nappe contacts, both along and across strike within the northeastern margin of the Lepontine dome and adjacent areas. Further to the northeast, the isotemperature contours reflect temperatures reached during the Late Eocene subduction-related blueschist-facies event and/or during subsequent near-isothermal decompression; these contours appear folded by younger, large-scale post-nappe-stacking folds. A substantial jump in the recorded maximum temperatures across the tectonic contact between the frontal Adula nappe complex and surrounding metasediments indicates that this contact accommodated differential tectonic movement of the Adula nappe with respect to the enveloping Bundnerschiefer after maximum temperatures were reached within the northern Adula nappe, i.e. after Late Eocene time.
Wiedergelesen
(2011)
Seit 2008 ergänzt die sowohl kleine als auch feine Rubrik "Wiedergelesen" die Ausgaben des außenpolitischen Fachjournals WeltTrends. Berühmte Bücher der Politologie und schätzenswerte Raritäten werden für die Füllung dieser Rubrik aus Bücherregalen herausgefischt, abgestaubt und in aktuellem Interesse gelesen - wieder gelesen. Stets ist es das Anliegen, die Schriften sowohl aus ihrer Zeit zu verstehen als auch für unsere Zeit nutzbar zu machen - z. B. Huntingtons The Clash of Civilizations, Lipsets Political Man, Paines Die Rechte des Menschen oder An Authoritarian Regime: The Case of Spain von Linz.
