甘肃省金塔县白石坝锡多金属矿地质特征及成因浅析

Geological characteristics and genesis of tin polymetallic deposit in Jinta County baishiba, Gansu Province

研究区位于甘肃北山造山带东部,哈萨克斯坦板块东缘,紧邻哈萨克斯坦板块、塔里木板块、华北板块的交汇部位,大地构造位置特殊,构造变形复杂,是金、铜、镍、钨、铁、锰等多金属矿产成矿的有利地段。研究区北侧已发现了白山堂铜铅矿、M-739铁矿、四道红山铁铜矿、大红山铁铜矿、玉山钨矿等。白石坝锡多金属矿的发现填补了该地区锡矿找矿发现的空白,对后期发现该类型矿产具有指导意义。

The study area is located in the eastern part of Beishan orogenic belt in Gansu Province and the eastern margin of Kazakhstan plate.It is close to the intersection of Kazakhstan plate,Tarim plate and North China plate.The tectonic position is special and the structural deformation is complex.It is a favorable area for gold,copper,nickel,tungsten,iron,manganese,etc.Baishantang copper lead deposit,m-739 iron ore,sidaohongshan iron copper mine,Dahongshan Iron Copper Mine and Yushan tungsten deposit have been found in the north of the study area.The discovery of baishiba tin polymetallic deposit fills in the blank of tin prospecting in this area and has guiding significance for later discovery of this type of mineral.
