东秦岭熊耳山地区骆驼山硫多金属矿床赋存规律及成因研究

Analysis on Causes and Occurrence Regularity of Luotuoshan Sulfide Polymetallic Deposit

总结归纳骆驼山硫多金属矿床的赋存规律和成因,主要是通过介绍矿床的控矿地质条件、赋存规律、矿床成因、成矿作用,以期为采用类比法寻找同类型的硫多金属矿床提供经验;矿床产于新元古界青白口系栾川群三川组大理岩所夹矽卡岩带中。矿体呈大的透镜状,产状与矽卡岩带展布规律一致;矿床矿种多,组份复杂,共生矿产主要有S、Cu、Wo_3、Zn、Ca F_2,伴生有益组分有Be、Cd、In、Ag等,以密集块状和浸染状矿石为主,矿床工业综合利用价值相对较高。

Summarize the occurrence regularity and causes of Luotuoshan sulfide polymetallic deposit,including introduce the ore-controlling geological conditions,regularity of occurrence,origin and mineralization,so as to seek the same type of sulfide polymetallic deposit by analogy; it was originated from Neoproterozoic erathem,in the marble skarn zone of Luanchuan-Sanchuan group,Qingbaikou system. The ore body was shaped in large lenticular,and the occurrence was no difference from skarn zone distribution; with many types of deposits and complex components,paragenetic minerals mainly are S,Cu,Wo_3,Zn,Ca F_2,associated with useful components such as Be,Cd,In,Ag,etc,which mainly were dense massive and disseminated ores,with a high industrial value.
