摘　　要：论述了不同类型基性层状侵入体的成因。根据母岩浆特征划分出玄武岩浆侵入体和拉斑玄武岩浆侵入体两大类。This paper deals with petrogenesis of different types of layered mafic intrusions wich, according to the characteristics of the parental magma, may be divided into two types: tholeiitic(i. g. Stillwater layered intrusion in U. S. A. and Skaergaard Lagered intrusion in east Greenland)and critical plane basaltic(i. g. Kiglapaid layered intrusion in Canada) layered intrusions.

关 键 词：层状岩体 拉斑玄武岩 临界面玄武岩 岩浆分离结晶作用
