摘　　要：层控型矿床主要包括非层状矿床以及层状矿床,矿化产在砂岩、页岩、砾岩、碳酸盐类岩层中,铜的硫化物交代岩石胶结物或在岩石空隙中分布,形成致密-浸染状矿石组成的层状矿体。层控型矿床的长度不等,既可以是数米长,也可以达到数千米的长度,层控型矿床的厚度不均,但通常都能达到数十米的厚度。主要矿物包括斑铜矿、黄铜矿、辉铜矿。矿石品位一般较高,在2%~3%之间。了解层控型矿床的特征是找矿的重要基础,只有结合层控型矿床的特征才能保证找矿的效率。基于此,本文介绍了新疆层控型矿床的特征,并就找矿方向进行探究,仅供大家参考。Stratabound deposits mainly include non bedded deposits and bedded deposits.Mineralization occurs in sandstone,shale,conglomerate and carbonate rocks.Copper sulfide metasomatizes rock cement or distributes in rock pores,forming a bedded ore body composed of dense disseminated ores.The length of stratabound deposits varies,ranging from several meters to thousands of meters.The thickness of stratabound deposits is uneven,but usually can reach tens of meters.The main minerals include bornite,chalcopyrite and chalcocite.The ore grade is generally high,between 2%and 3%.Understanding the characteristics of stratabound deposits is an important basis for prospecting.Only combining the characteristics of stratabound deposits can ensure the efficiency of prospecting.Based on this,this paper introduces the characteristics of stratabound deposits in Xinjiang,and explores the prospecting direction for your reference only.
