蒙古国中戈壁省某铁多金属矿床地质特征及找矿标志

Geolocal characteristics and prospecting indicators of an iron-polymetallic deposit in the central Gobi province of Mongolia

蒙古国中戈壁省某铁多金属矿床为一中型矽卡岩型矿床。矿区共圈出铁多金属矿体16个,其中主要矿体2个,矿体最大延长1000m,最大延伸350m,最大厚度150m。TFe平均品位32.52%。估算铁矿石资源量5000万t。在成矿地质背景及矿床地质特征讨论的基础上,提出该类型矿床的找矿标志,以期为类似条件下寻找铁矿提供参考。

An mine is a middle-sized skarn-type iron-polymetallic deposit in the Central Gobi Province of Mongolia .In this deposit ,1 6 iron-zinc-polymetallic ore bodies have been delineated ,of which 2 bodies are of major sizes .The maximum length is 1000m ,the maximum deep extention is 350m ,and the maximum thickness is 150m .Their average grades of TFe are 32 .52% .The resource amount of Fe is estimated to be 5000 × 104 ton .Based on the discussion on the ore-forming geological background and ore deposit geology characteristics ,the authors put forward the prospecting criteria for this type of ore deposits ,which is the reference for discovery iron deposit in areas with similar geological condition .
