Mineralogical and Geochemical Characteristics of the Zhuopan Alkaline Complex in Yunnan Province and Their Geological Significance

Abstract

Abstract:

The Zhuopan alkaline complex is located in the western Lanping basin and is an important part of the Jinshajiang-Ailaoshan alkali-rich intrusion belt. The Zhuopan alkaline complex is mainly composed of gabbro, pyroxenolite and syenite,and their K₂O contents of the whole rock vary from 1.98% to 8.97%; the Na₂O contents are from 0.52% to 6.62%, the Na₂O+K₂O contents are from 1.98% to 8.97% and the K₂O/Na₂O ratios change between 0.35 and 11.15, indicating that they belong to the high K, alkali-rich shoshonite series.Electron microprobe analysis(EMPA)indicates that the pyroxene is dominated by the diopside; the feldspar is mainly albite (An<5) and orthoclase feldspar; and biotite is Mg-biotite in the complex rock.Pyroxene thermometer calculation shows that the crystallization temperature was from 1,070 to 1,490 ℃.According to the geochemical characteristics of the different rocks and minerals,we deduce that the Zhuopan alkaline complex was sourced from a magmatic system with high oxygen fugacity and iron content and formed in a transition tectonic setting changing from post collisional compression to extensional environment.

Key words: Zhuopan alkaline complex, EMPA, pyroxene, biotite, feldspar, Yunnan Province
