- W2385388619 abstract "In order to study the Permian paleoenvironment of the Jiaomuri area(Qiangtang Basin), geochemical analysis were takenfrom the dolomite samples of Lower Permian Zhanjin Formation and limestone samples of Middle Permian Longge Formation. Our datashow that the average of the Y/Ho ratio is 45.14 while element Gd shows light positive anomaly, suggesting normal marine carbonatecharacteristics. The contents of Si O2 and Al2O3are low indicating relatively limited terrestrial input. The low total REE contents(ΣREE) and the different LREE and HREE values of the samples indicate that REE were removed and LREE were fractionated moreeasily than HREE. The samples have obviously negative Ce and Eu anomalies showing an oxidizing paleoenvironment, which furthersupported by the analysis of V/Cr, V/(V + Ni), Sr/Ba and Sr/Ca ratios. Up-section, the Permian samples showed higher salinity andoxidbillity, which was supposed to be related to water depth shallowing related to a local compression tectonic trend." @default.
