| 摘 要： | 沈坝金矿位于秦岭褶皱系南缘,为化探异常发现的金矿床。矿体赋存在志留系下统的梅子垭组第二岩性段中亚段的岩层内。炭质黑云母变斑晶绢云石英片岩夹含炭变质砂岩为含矿主岩。矿床内综合利用元素低,为单一的金矿床。矿石中的As含量甚微,表明该矿床不同于展布滇黔桂接壤区和西秦岭地区的微细浸染型(卡林型)金矿床。

| Abstract: | Shenba gold deposit locates at south rim of Qingling fold system and it is a gold deposit which is found by geochemical prospecting anomalies.The ore bodies occur in rock stratum of sub-section of second lithological section of Meiziya formation of lower silurian system.The ore-bearing host rock is carbon biotite metacrystal sericitized quartz schist which contains carbon metasandstone.Other elements in the deposit are low and the deposit is a monometallic gold deposit.The content of As in ores is little,which suggests that the deposit is different from superfine impregnated （Carlin-type）gold deposits which distribute in contiguous area of Yunnan,Guizhou and Guangxi and west Qingling area. |
