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.

目前，对于与此类型矿床找矿相关的若干成因问题的认识，还相当模糊，主要表现在以下几方面：①对此类型矿床的产出构造背景认识不清；②认为含矿岩石为镁质大理岩或镁质夕卡岩；③认为含矿岩石中与红宝石共生的角闪石为透闪石；④认为此类矿床的成因类型为&气成一热液型&或&夕卡岩型&。本文在实际研究(王礼胜，1996)和文献资料整理的基础上，分别对这些问题给予了澄
