陕西小秦岭地区的环形构造及其控矿作用探讨

THE CIRCULAR STRUCTURE AND ITS MET ALLOTECT IN THE XIAOQINLING AREA OF SHAANXI PROVINCE

本文运用波浪镶嵌构造观点研究小秦岭地区发育着的许多大小不等的环形构造。它与区域北东向、东西向构造相互交织形成的网格构造相互套合,共同组成了该区的复杂构造形态。环形构造对矿产、尤其对同生金属矿产起着明显的控制作用,研究环形构造,将对矿产的普查勘探及成矿预测起到一定的作用,

According to the wavy-mosaic structure hypothesis,the writers discussed the circular structures with various sizes in the Xiaoqinling area. The mutual interweave of the regional structures in the NE and EW trends which formed the network structures and those circular ones jointly made up the complicated structural pattern in this area.The ore deposits, especially those synogenetic metallic resources occurring ia this area,are evidently controlled by the circular structures.So,the studies of the circular structures will have a certain usefulness for reconnaissance survey and metallogenetic prognosis.
