摘要
本文在收集整理与"磐龙玉"矿床相关的地质资料基础上,对该矿床的一般地质特征和成因进行归纳总结。"磐龙玉"玉矿体赋存于下二叠统大河深组地层中,受控于Ⅰ号和Ⅱ号两条矿化带内,分布有10条矿体。矿石属石英质玉,玉石质量好,矿石自然类型为硅化岩型,玉矿床的成因属于与火山碎屑岩类及变质岩类(板岩)有关的低温热液矿床,南北向压扭性构造是玉矿体的重要找矿标志。
On the basis of collecting and sorting out the geological data related to the"panlongyu"deposit,this paper summarizes the general geological characteristics and genesis of the deposit:"panlongyu"jade ore body occurs in the lower Permian daheshen formation,controlled by No.I and No.II mineralization belt,with 10 ore bodies distributed;the ore belongs to quartz jade,with good quality,and the natural type of ore is silicification The genesis of the jade deposit belongs to the low temperature hydrothermal deposit related to pyroclastic rocks and metamorphic rocks(slate),and the North-South compression torsion structure is an important prospecting indicator of the jade ore body.
