赣北东雷湾铜钨矿床地质特征及找矿前景分析

Geological Characteristics and Prospecting Prospect of Dongleiwan Copper-Tungsten Deposit in Northern Jiangxi Province

东雷湾铜钨矿是20世纪60年代发现的小型铜矿床,因矿床规模小,矿体控制程度低,多年来,一直未开发。本文在综合以往资料的基础上,结合近期开展的资源储量核实资料,通过对铜钨矿体特征论述,发现矿区钨矿品位较均匀,连续性好,矿床是以钨为主,共生铜的矽卡岩型矿床,是本区继通江岭矿区发现铜钨矿床之后的又一次新发现,通过对矿床成因及控矿因素的初步分析,认为沿东雷湾岩体接触带有较好的找矿前景,相关成果对矿区下步勘查及矿床开发具有重要的指导意义。

Dongleiwan copper-tungsten deposit is a small copper deposit discovered in 1960s.It has not been developed for many years because of its small scale and low degree of ore body control.On the basis of previous data,combined with the verification data of resource reserves recently carried out,through the discussion of the characteristics of copper tungsten ore body,it is found that the tungsten ore grade in the mining area is relatively uniform,and the continuity is good.The deposit is a skarn type deposit with tungsten as the main component and coexisting copper.It is another new discovery in this area after the discovery of copper tungsten deposit in tongjiangling mining area According to the analysis,it is considered that there is a good prospecting prospect along the contact zone of dongleiwan rock mass,and the relevant achievements have important practical significance for the next exploration and deposit development of the mining area.
