浙江省上冯矿区成矿元素分布规律及地质意义
|
摘要
本文通过对上冯矿区微量元素的分布特征、元素比值的分带特征的研究,探讨了成矿流体的运移方向,并对矿床成因进行判别;认为铜矿勘查应侧重于在南西部花岗斑岩岩体浅部,钼矿勘查应针对岩体接触带,尤其是矿区南西深部花岗岩顶部的构造薄弱地带应为矿体有利赋存部位。
Based on the research of the distribution of trace elements and elements ratios zoning,the authors investigated the channel way and direction of ore fluid migration in this mine and judged the genetic type of ore deposit.According to this,we recognize the shallow part of granite-porphyry in the south-west may be favourale sections for prospecting copper deposits.The exploration of molybdenum ore should aim at the contacts,especially the areas of weakness in the top part of the granite,which may be the favorable sections of the molybdenum mineralization.
