摘 要: | 大理岩型红宝石矿床是红蓝宝石矿床的最重要类型之一。对此类型矿床与找矿相关的若干问题,长期存在模糊认识。本文经过实际研究和相关文献资料的搜集整理,得出了以下重要结论:大理岩型红宝石矿床产于有深大断裂构造活动的深成造山变质带;矿床成因类型属区域热动力变质型;含矿岩石是钙质结晶大理岩,而非镁质大理岩或镁质矽卡岩;含矿岩石中的角门石为富铝贫硅含铬的钙质问石,而非绿色透闪石。

Abstract: | Ruby deposit of marble type is one of the most important types of ruby and sapphire deposits. For a long period, some problems concerned with prospecting direction of this kind of deposits have been misunderstood. By sutdy and gathering information, some important conclusions are presented: (1) Ruby deposits of marble type were located in the plutonic metamorphic zones of orogene where deep-seated fault structure is developed; (2) Genesis of the deposit belongs to the type of thermal-dynamic metamorphism; (3) Ruby-bearing rocks are calcic crystalline marbles, not magnesian marbles; (4) Amphiboles in ruby-bearing rocks arenot tremolites, but silica-poor alumina-rich and chrome-bearing calcic amphiboles. |
