Petrology and Geochemistry Characteristics of Magmatic Rocks in Kongdian Formation in the Huanghua Depression
摘要
Abstract
Based on the Petrographic and geochemical study of the Lower Tertiary Kongdian formation basalt and diabase in Huanghua Depression,we suggest that basalt and diabase belong to alkaline series with LREE enrich-ment and no Eu anomality. The magma evolution was mainly controlled by the mantle partial melting with little crystallization differentiation and little crustal contamination. Tectonic environment discrimination results show that the magmatic rocks of the Kongdian formation formed in intraplate environment.关键词
