赣北彭山地区老屋舒矽卡岩型锡矿床地质特征及找矿前景
Geological characteristics and prospecting prospects of the Laowushu skarn-type tin deposit in the Pengshan area,northern Jiangxi
摘要
Abstract
[Objective]The Laowushu tin deposit is located in the northwest of the Pengshan tin polymetallic ore cluster in northern Jiangxi Province.It is a newly discovered skarn-type tin deposit in recent exploration.The existing exploration project single hole revealed a skarn-type ore body with a thickness of 15.77 m and an average Sn grade of 1.2%.It is produced along the outer contact zone of the rock body.It is the tin ore body with the highest grade and the largest thickness found in the Pengshan tin polymetallic ore cluster.However,its mineralization conditions and mineralization potential are still unclear.[Methods]Based on the summary of previous research results and new discoveries in exploration work,this paper conducts a comprehensive study on the ore body characteristics and ore characteristics of the Laowushu deposit.[Results]It is proposed that,unlike other mining areas in the Pengshan tin polymetallic ore cluster,the skarn-type tin ore bodies in the Laowushu mining area are mainly distributed in the outer contact zone of carbonaceous shale interbedded with dolomite limestone and granite at the bottom of the Hetang Formation.The mineralization process is divided into three mineralization stages:skarn mineralization stage,oxide mineralization stage,and quartz-sulfide mineralization stage.[Conclusions]A comprehensive analysis of the mineralization conditions of the mining area was conducted based on the characteristics of magmatic rocks,surrounding rocks and structural geology,and it is believed that the Laowushu skarn-type tin mining area in Pengshan area has good prospecting prospects.关键词
