引言七十年代以来,许多研究者对马坑铁矿进行过深入的研究。关于该矿床的形成机制,特别是含矿建造中一套中一基性岩石和矿体底板岩石的成因,以及矿石的形成方式等问题,曾引起研究者们的特别关注,并开展了热烈讨论。笔者曾对该矿床的地质一地球化学特征进行了较为详细的研究,并指出它是与石炭纪海底火山活动有关的喷气-热液沉积矿床,成矿流体来源于地热对流海水与玄武岩的反应。本文是上述研究的继续和深入,目的在于为
Introduction Since the 1970s, many researchers have conducted an in-depth study of the Makeng iron mine. The formation mechanism of this deposit, especially the formation of a set of medium-basic rock and ore body floor rock in ore-bearing construction and the formation of ore have drawn special attention of researchers and have been heatedly discussed . The author has conducted a more detailed study on the geochemical-geochemical characteristics of this deposit and pointed out that it is a jet-hydrothermal sedimentary deposit related to the Carboniferous submarine volcanic activity. The ore-forming fluid is derived from the reaction of geothermal convective seawater and basalts. This article is the continuation and deepening of the above research, aimed at
