浙江省青田县石平川钼矿床新发现及找矿前景

长期以来,石平川钼矿床一直被认为是典型的石英脉型矿床,矿体分布于石平川岩体内外接触带上下100m以内。经过近年的地质工作发现,距石平川岩体外接触带400m~500m的侏罗系西山头组第二岩性段地层中存在细脉型辉钼矿体,从而形成下部大脉型石英辉钼矿体、上部细脉型辉钼矿体的二元结构。这一发现为开展深部及外围找矿,扩大资源储量规模提供了新的前景。

New discovery and ore-search prospect in the Shipingchuan molybdenum deposit of Qingtian county, Zhejiang Province

For a long time, the Shi Pingchuan molybdenum deposit in Qingtian county, Zhejiang Province has been considered a typical quartz-vein like, where ore bodies are distributed within 100m above and below the inner and outer contact zones of the Shipingchuan rock mass. While geological work in recent years found that a stringer vein type of molybdenum ores is present in the second lithologic section of the Jurassic Xishan Formation 400-500m to the outer contact zone, which is a dualstructure of the large quartz vein type in lower part and the fine vein type molybdenite ore in upper part. This discovery provides a new prospect for deep and peripheral prospecting and to expand the scale of resource reserves.
