甘肃省矿床成矿系列研究

通过对省内矿床的形成时代、成矿环境、地质成矿作用及矿床"自然组合"的研究认识,认为矿床是地质环境中的组成部分,成矿作用是形成地质环境的地质作用中的一个组成部分;在各个地质历史阶段的地质构造环境(单元)中的矿床与一定的地质成矿作用有关。利用在一定的地质历史时期或构造运动阶段,在一定的地质构造单元及构造部位,与一定的地质成矿作用有关,形成一组具有成因联系的矿床的自然组合这一成矿系列概念,基本确定了甘肃省内成矿系列序次,重点是对成矿系列进行了划分和鉴别,提出全省有11个成矿系列类型、39个成矿系列的新认识。论证了成矿系列的产出特征,确定出各系列的矿床式。

STUDY ON MINEROGENETIC SERIES OF DEPOSITS IN GANSU PROVINCE

By studying the ore forming time,environments,geological mineralization and natural ore forming assemblage of deposits in Gansu Province,it is supposed that deposit is a part of geological environment,mineralization is the a part of geological process which is composed of geological environment;deposits in geological structural unit during various period of geological history has the relation to a certain geological mineralization.By means of the concept of minerogenetic series,that in the certain geological structural unit and location,a period of geological history or structural movements has relations to a geological mineralization which formed a series of deposits,the sequences of minerogenetic series in Gansu Province are decided primarily,minerogenetic series are classified and identified as 11 types of minerogenetic series and 39 series.
