Systematics of Trace Elements in Sediments from the North-Western Caucasus Mud Volcanoes

A study of trace elements in sediments from the North-Western Caucasus mud volcanoes reveals significant geochemical heterogeneity, indicating a diverse composition of their sources. Unlike other regions such as the Junggar Basin and Andaman Islands, these sediments show a wide range of compositions, mixing 'felsic' and 'mafic' components in varying proportions (~100:1 to 50:50). This suggests a complex geological history, with contributions from both felsic (granitic) and mafic (basaltic) rocks. The research compares trace element distributions with global standards like PAAS (average Australian post-Archean shale) and local clays, highlighting unique patterns in elements such as Mo, Sr, Y, Nb, and Ba. Geochemical diagrams further support the presence of both immature and mature components, offering insights into the region's geological evolution.
