| 摘 要： | 下古生界呼兰群变质岩系位於吉林褶皱带南端,其中泥质岩变质片岩段具有明显的递进变质作用,并可划分为:铁铝石榴石带、十字石带、蓝晶石带、硅线石带四个矿物带,呈中压中温巴洛式变质带特征。本文对该变质带矿物组合、原岩建造、变质作用演化、成因机理及其地质意义进行了探讨。

| Abstract: | The lower Paleozoic Hulan metamorphic series is located in the folded belt, southern margin of Jilin, in which the argillaceous rock and metamorphous schist have obviously progressive metamorphism which can be derided into four mineral belts, i.e.almandine, staurolite, kyanite and sillimanite, showing the characteristics of intermediate temperature-pressure Barlor type metamorphic belt. In this paper, mineral assemblage, protolith formation, metamorphic evolution, genetic mechanism as well as geological significance are discussed. |
