Mineralization Characteristics of Gems in Ailaoshan Structural Belt, Yunnan Province

摘要: 哀牢山构造带是云南重要的地质构造,也是云南宝玉石成矿集中区。已发现的宝玉石均产于深变质岩带中。主要的宝石矿床有变质—交代型(常说的大理岩型)的红宝石矿床和伟晶岩型的海蓝宝石、黄玉、红色绿柱石、水晶等矿床。变质—交代型矿床以元江小羊街红宝石矿床最典型,伟晶岩型的典型矿床有元阳县黑石头海蓝宝石、黄玉矿床及元阳告封碑红色绿柱石、黄玉、绿柱石矿床等。

Abstract: Ailaoshan structural belt is the important geologic structure and is also the gem concentrated mineralization area in Yunnan Province. All the gems that have been discovered occur in the hypometamorphic rock belts. The main gem deposits include metamorphic-matasomatic-type (commonly called marble type) ruby deposits and pegmatite-type deposits of aquamarine, topaz,red beryl,rock crystal and so on.For the metamorphic-matasomatic deposits, the Xiao-yangjie ruby deposit in Yuanjiang County is the most characteristic and, for the typical pegmatite deposits, it is the Heishitou aquamarine and topaz deposits in Yuanyang County and the Gaofengbei red beryl, topaz and beryl deposits also in Yuanyang County.
