| 摘 要： | 大理岩型红宝石矿床是红蓝宝石矿床的重要类型。对此类型矿床与找矿相关的成因问题，长期存在模糊认识。本文在实际研究和文献资料整理的基础上，得出以下结论：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；含矿岩石是钙质结晶大理岩，而非鲜质大理岩或镁质夕卡岩；含矿岩石中的角闪石为富铝贫硅含铬的钙质闪石，如含铬的镁砂川闪石，而非绿色透闪石；矿床成因类型属区域热动力变质型，而不是“气成－热认型”或“夕卡岩型”。

| Abstract: | Ruby deposits in marbles are the most important source of ruby. For a long period, some problems concerning the prospecting of this type of deposit have been misunderstood. On the basis of a study and elaboration of data, some important conclusions are presented: (1) ruby deposits in marbles occur in the plutonic metamorphic zones of orogens where deep fault structure is developed; (2) ruby-bearing rocks are calcic crystalline marbles, rather than magnesian marbles; (3) amphiboles in ruby-bearing rocks are not tremolites, but silica-poor, alumina-rich and chrome-bearing calcic amphiboles, such as chrome-bearing magnesio-sadanagaites; and (4) the deposits are genetically of thermodynamical metamorphism type, rather than of pneumatolito-hydrothermal type or skarn type. |
