发布时间：2018-08-24 17:05
【摘要】：燕山期中国东部出现了大规模的岩浆活动和成矿事件,探明其发生的地球化学动力学背景以及矿床成因机制,对理解中国东部中生代以来构造格局转变和指导找矿都具有重要意义。本文将从以下5个方面入手,探索古太平洋构造域的岩浆作用与成矿机制:(1)下扬子和江南隆起区燕山期岩浆-成矿作用研究;(2)中国东部燕山期成矿与不成矿埃达克岩及中-新生代玄武岩研究;(3)东秦岭造山带中生代岩浆作用与成矿研究;(4)不同类型钼矿床的钼同位素研究;(5)中国中东部燕山期富碱侵入岩石/正长花岗岩研究。
[Abstract]:Large scale magmatic activities and metallogenic events occurred in eastern China during the Yanshanian period. The geochemical dynamic background and genetic mechanism of the deposits were proved. It is of great significance to understand the tectonic pattern change since Mesozoic in eastern China and to guide prospecting. This paper will start with the following five aspects: Study on magmatism and metallogenic mechanism of paleo-Pacific tectonic region: (1) Yanshanian magmatic and metallogenic study of Lower Yangtze and Jiangnan uplift; (2) study of Yanshanian metallogenic and non-metallogenic adakite and Meso-Cenozoic basalt in eastern China (3) Mesozoic magmatism and metallogeny in the eastern Qinling orogenic belt; (4) molybdenum isotopic studies of different types of molybdenum deposits; (5) study of alkali rich intrusive rocks / syenite in central and eastern China.
