Through coring in the lacuster of Angulinao Lake, testing the eight kinds of ions( K +、Na +、Ca 2+ 、Mg 2+ 、 CO 3 2- 、 HCO 3 -、Cl - and SO 4 2- ) and other related geochemical features, and analyzing the correlation among the ions, the curves of soluble salt distribution and soluble salt indictors have been drawn.
The contents of rare earth elements are high with ∑REE of 135.67×10-6～407.71×10-6,light REE enriched slightly with(La/Yb)N of 2.55～3.73,Eu has an obvious anomaly with δEu of 0.34～0.54.The geochemical characteristic of rhyolitic rocks is also similar to that of rhyolite in the bimodal volcanics of the typical back-arc basin.
Geochemical characteristics and zircon U-Pb isotopic ages of island-arc basic igneous complexes from the Tianshui area in West Q
The geochemical characteristics of intermediate-basic igneous rocks indicate that they belong to a tholeiite suite.
Geochemical characteristics of sediment pore water from Site XS-01 in the Xisha trough of South China Sea and their significance
This paper introduces the geological background, mineral association, and lithology of the exhalative rock, and discusses its REE geochemical characteristics and connection with hydrothermal environment.
Geochemical Characteristics of Organic Matter from Maikop Rocks of Eastern Azerbaijan
Sedimentary geochemistry of chert from the Middle-Upper Ordovician in Shihuigou area, North Qilian orogenic belt and its tectoni
The geochemistry of chert from the Zhongpu Group reveals that all cherts coexisting with island-arc volcanic rocks formed in a continental margin basin environment.
Sr, Nd and O isotope geochemistry of the mafic-ultramafic complexes in the southern margin of the Altay orogenic belt and discus
Elemental and Sm-Nd isotopic geochemistry on detrital sedimentary rocks in the Ganzi-Songpan block and Longmen Mountains
Systematic results of major and trace element geochemistry and Sm-Nd isotopic geochemistry on detrital sedimentary rocks of Precambrian to Triassic in the Ganzi-Songpan block and Longmen Mountains are presented.
This paper shows a typical Chihsian depositional rhythm composed of the massive and the laminated limestones with ecological and geochemical features.
Massive bioclastic limestone from the rhythm was aerobic in paleoxygenation condition indicated by both the ecological and geochemical features.
Facies and Geochemical Features of the Iron Ore Complex of the Kerch Peninsula
Isotope-geochemical features of the formation of carbon and oxygen isotopic compositions in sedimentary and diagenetic carbonates are considered.
These correlations probably testify to the formation of different phases of mud-volcanic emanations in a single geochemical system and suggest the crucial role of temperature in the development of isotope-geochemical features.
