综合东西伯利亚和远东高压岩石杂岩体分布地区地质资料表明 ,上述地区多为地动力高度活化地块区 ,并具专属性特点 .应用地质构造、物质组分 -矿物学特征 ,详细地划分了 7种类型高压变质岩石组合 ,并根据化学特性 ,划分了 3种岩石化学类型 ,即辉长 -玄武岩、橄长岩、橄榄岩 (二辉橄榄岩 )类型 .此外 ,论述了取决于原岩基质组成的变质反应特征 ,其规模直接与原岩基质的组成 ,特别是与 Al2 O3、Na2 O、Si O2 的组成密切相关 ,即当 Al2 O3、Na2 O、Si O2 过饱和时 ,形成辉长 -玄武岩质岩石化学类型 ;当上述组分严重不足时 ,则形成橄榄岩质 (或二辉橄榄岩质 )岩石化学类型 .在上述组分过剩的变质反应过程中 ,则形成金 (或铂 )矿化交代岩 ,并具有实际意义 .
According to the geological data of the distribution of the high-pressure rock complex in East Siberia and the Far East, the above areas are mostly geologically active and highly activated, and are characterized by their own characteristics.Using geological structure, material composition and mineralogy characteristics, Seven types of high-pressure metamorphic rocks, and according to their chemical characteristics, three types of petrochemistry, ie, gabbro-basalt, caffolinite and peridotite (lherzolite) types, are distinguished. In addition, Composition of the metamorphic reaction characteristics, the scale directly with the composition of the original rock matrix, especially with Al 2 O 3, Na 2 O, Si O 2 composition is closely related to that when Al 2 O 3, Na 2 O, Si O 2 supersaturation, the formation of glow- Basaltic rocks Petrochemical types; when the above components are severely deficient, they form a petrochemical type of peridotitic (or lherzolites) gold. During the excess metamorphic reaction of the above components, gold (or platinum) is formed To explain the rock, and has practical significance.
