摘要
河南省岩浆活动显示多期活动的特征,侵入岩较发育,占全省基岩出露面积的23.5%以上,岩石类型齐全,与其有成生联系的矿产资源丰富。文章参考潜力评价全国构造侵入岩带的总体划分方案,结合河南省岩浆岩分布特征、岩石类型、岩石组合及岩浆岩的演化规律,划分出2个构造侵入岩省、5个构造侵入岩带、12个构造侵入岩亚带、进一步划分出22个构造侵入岩段,并对其基本特征及与成矿关系进行总结。
In Henan province,the magmatic activity shows its feature of multi-stage,while the intrusive rocks are widely distributed and accounts for more than 23.5% of the total bedrock outcrop area.The multiple rock types result in abundant genetic correlative mineral resources.Based on the division of national tectonic intrusive zone,and according to the distribution of igneous rocks,rock types,rock assemblages and evolu-tion of igneous rocks in Henan,the author creates 2 tectonic intrusive rock provinces,5 structure intrusive rock belts,12 structure intrusive rock sub-belts,and 22 tectonic intrusive rock segments.The basic charac-teristics and mineralization relationship are concluded in this paper.
