摘要
华北克拉通从1 800Ma形成的克拉通化到燕山板块造山带的形成,经历了复杂的构造演化历史。晚古生代期间,古中亚洋向华北板块俯冲消减,华北北缘在此期间有大量的岩体侵入。多年来,华北地缘丰宁上黄旗岩浆岩成矿作用一直是国内地质工作者研究的一个重要课题。本文试探针对河北上黄旗一带侵入岩岩体水系沉积物的数据综合分析,进而对该区侵入岩体型矿产成矿指示作用进行试探性预测。
The Huabei Craton from 1 800 Ma cratonization to Yanshan plate orogenic belt,has experienced complicated tectonic evolution history.During the late Paleozoic,the subduction of the Central Asian Ocean to the North China plate,during a large number of intrusions occurred.Over the years,Shanghuangqi Fengning North China magmatite mineralization has been an important topic in domestic geologists study.This paper tries to comprehensive analysis of the data on Shanghuangqi Hebei sediments along the intrusive rock,and tentatively indicate mineral metallogenic prediction.
