崇阳县大湖山岩体北缘多金属矿成矿规律

Metallogenic Regularity of Polymetallic Deposits in the Northern Margin of the Dahushan Rock Mass in Chongyang County

近年来在大湖山岩体北缘发现了一些新的找矿线索,岩体周围分布着斯门坳钨矿、梯冲锌矿、羊角埚金矿、周家坪金矿等矿床(点)。为探讨该区域多金属矿成矿规律,通过对4个矿床(点)的成矿地质特征进行简述,从矿床的空间分布特征、控矿因素以及矿床成因等3个方面总结了其成矿规律。认为大湖山岩体与成矿关系密切,为成矿提供了部分物质来源。区内矿床点的展布随着离岩体越远,表现出了从高温元素钨→中温元素锌→低温元素金的一个渐变的过程。

In recent years,some new prospecting clues have been discovered in the northern margin of the Dahushan rock mass,There are deposits such as the Simenao tungsten mine,the Tichong zinc mine,the Yangjiaoguo gold deposit,and the Zhoujiaping gold deposit around the rock mass(point).In order to explore the metallogenic regularity of polymetallic ore in this area,through the mineralization geological characteristics of four deposits(points),The metallogenic regularity is summarized from three aspects:the spatial distribution characteristics of the deposit,the ore-controlling factors and the genesis of the deposit.It is believed that the Dahushan rock mass is closely related to mineralization,providing some material sources for mineralization.The distribution of the deposit points in the area is far from the rock mass,showing a gradual process from high temperature elemental tungsten to medium temperature elemental zinc to low temperature elemental gold.
