近年来在苏联各地区发现并研究了花岗岩及外貌上与正长岩相似的长石交代岩,与其有关的矿化有铍、钽—铌、锆、稀土以及萤石或冰晶石等。 它们形成一种独特的矿床成因类型(或成因组),其主要特征在有关的文献中已有描述。 长石交代岩的矿床,有的产于地台基底长期活动作用带内,少数是在有中间岩块的褶皱区。它们大部份都是分布在前寒武记的深大断裂带中,而有时则产于这种断裂带与次生共轭断裂的交叉处。成矿交代岩
In recent years, granite and feldspar metamorphic feldspar metamorphic rocks have been discovered and studied in various regions of the Soviet Union. Beryllium, tantalum, niobium, zirconium, rare earth, and fluorite or cryolite have been associated with mineralization. They form a unique type of genesis (or causality) of the deposit, the main features of which have been described in the relevant literature. Feldspar metamorphic rocks deposit, and some produced in the platform basement long-term activity within the band, a few are in the middle of the rock fold area. Most of them are distributed in the deep Cambrian Precambrian fault zone, and sometimes produced in the fault zone and the secondary conjugate fracture intersection. Metallogenic rock
