名  称：银锡矿石

矿物成分：矿石矿物主要为辉银矿、方铅矿、闪锌矿、锡石，其次为黄铜矿、黄铁矿、银黝铜矿；脉石矿物主要为石英、绿泥石及绢云母，少量白云石、黑云母及高岭石。

成因类型：脉状热液型

成矿时代：早白垩世

主要用途：提取银、锡、铅、锌的主要矿石原料。银的用途较为广泛，传统上制造货币和首饰；在工业上银多用在电子和机械制造业。锡具有展性强、防锈、耐腐蚀等特性，锡能够同其他金属及类金属形成各种合金，易于镀在许多金属表面，特别是锡的表面耐蚀不锈，同有机酸及盐类反应的生成无毒。

采集地点：内蒙古西乌珠穆沁旗白音查干东山银锡多金属矿区

Name：Silver- Tin Ore

Mineralogy：Ore minerals dominated by argentite, galena, sphalerite and cassiterite, with minor chalcopyrite, pyrite and freibergite. Gangue minerals include mostly quartz, chlorite and sericite, with minor amount of muscovite, biotite and kaolinite.

Genesis：Hydrothermal veins.

Age：Early Cretaceous.

Usage：Major source for extracting silver, tin, lead and zinc. The usage of silver covers large area. Traditionally silver was used for making coins and jewelries, in industry silver is mostly used in electric and machinery manufacture. Tin is good at ductility and erosion resistant, therefor be able to combine with other metals to form alloys on the surface of metals. Tin is resistant to erosion, the resultant of the reaction with organic acid and salts is non-toxic.
