赣东刘源与闽西天井坪斜长角闪岩成因对比

A CORRELATION OF THE GENESIS BETWEEN LIUYUAN AMPHIBOLITE,EAST JIANGXI AND TIANJI-NGPING AMPHIBOLITE,WEST FUJIAN

该文将赣东刘源斜长角闪岩与相邻的闽西天井坪斜长角闪岩进行了岩石学和变质作用方面的对比．作者认为两地的斜长角闪具有相同的原岩，又处在同样的大地构造环境中，经过了相近的变质作用，属同一时代产物，因此，将两地的同类变质岩组合归入早－中元古界．

A correlation of petrography and metamorphism has been made onthe Liuyuan amphibo ite,East Jiangxi and the neighbouring Tianjingpingamphibolite,West FuJian.The author holds that both of them havethe same protolith and the same geotectonic.And the same time,theyunderwent similar metamorphism and belong to the products of the samegeological age.Therefore, the metamorphic rock assemblages of thesame type in the two places can be classified into Early-Middle Pro-terozoic Era.
