【摘要】：燕山期中國東部出現(xiàn)了大規(guī)模的巖漿活動(dòng)和成礦事件,探明其發(fā)生的地球化學(xué)動(dòng)力學(xué)背景以及礦床成因機(jī)制,對(duì)理解中國東部中生代以來構(gòu)造格局轉(zhuǎn)變和指導(dǎo)找礦都具有重要意義。本文將從以下5個(gè)方面入手,探索古太平洋構(gòu)造域的巖漿作用與成礦機(jī)制:(1)下?lián)P子和江南隆起區(qū)燕山期巖漿-成礦作用研究;(2)中國東部燕山期成礦與不成礦埃達(dá)克巖及中-新生代玄武巖研究;(3)東秦嶺造山帶中生代巖漿作用與成礦研究;(4)不同類型鉬礦床的鉬同位素研究;(5)中國中東部燕山期富堿侵入巖石/正長花崗巖研究。
[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.
