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。
The large-scale magmatism and metallogenesis occurred in eastern China during the Yanshan Period, and its geochemical kinetic background and the genesis mechanism of the orebodies are proven. This is of great significance for understanding the tectonic transformation and guiding ore prospecting since the Mesozoic in eastern China. This paper will explore the magmatism and mineralization mechanism of the Paleo Pacific tectonics from the following five aspects: (1) the Yanshanian magmatic-mineralization in the Lower Yangtze and Jiangnan Uplift; (2) (3) the study of Mesozoic magmatism and mineralization in the East Qinling orogenic belt; (4) the study of molybdenum isotopes in different types of molybdenum deposits; (5) the enrichment of Yanshanian rich in central and eastern China INVESTIGATION OF ALKALINE INVASIONAL ROCK / FELLOW GRANITE.
