浅析湖南九嶷山矿田锡矿类型及找矿方向

THE SHALLOW ANALYSIS OF TIN MINE AND LOOK FOR THE MINE DIRECTIONOF JIUYISHAN MINE AREA IN HUNAN

湖南九嶷山矿田是南岭地区重要的锡矿成矿远景区之一,具有优越的成矿地质条件。锡矿类型较多,主要以云英岩体型、蚀变花岗岩型为主,具有矿体厚度大,蚀变强,品位中等,矿石利用性能好的特点。为了日后在本区找矿有更大的突破,通过研究区内控矿地质条件、主要矿床类型及时其特征,初步分析了区内矿床的找矿方向。认为燕山早期第一阶段晚期次及燕山早期第二阶段早期次侵入体与近南北向或北东向断裂带接触的部位,是寻找钨锡多属矿床的最有利的区段。

The Hunan jiuyishan mine area are one of important tin ore one-tenth mine distant view areas of Nan Ling district , and possess the superior one-tenth mine geology condition . The tin ore type is many , and it is major with Yun Yingyan＇ s type of figure and losing to become the ganite mould to give first place to , possessing mineral thickness greatly , losing becoming strong , the grade is medium , the good characteristic of ore utilization capability . Looking for the mine to have the bigger breakthrough in this area for , by way of accuse mine geology condition inside studying the area and major mineral deposit type his characteristic promptly , the mine direction is looked for in the initial analysis mineral deposit inside the area in the future . Thinking that Yanshan early stage stage 1 late period degree reaches Yanshan early stage stage in early stage more inferior incursion body easternly with closely northern and southern direction or east and north direction faces splitting taking the position of contact is seeks the tungsten tin much the most advantageous area of category mineral deposits section.
