摘　　要：在一定程度上我国辽宁省矿产资源较为丰富,伴随着辽宁省社会经济的不断发展,现已经有相当多的矿产资源被得以开发利用。辽北地区菱镁矿床是位于新元古代凡河裂谷东南边缘-清原克拉通北部边缘,主要是有多个矿体所构成。菱镁矿矿床所赋予在中元古界长城系高于桩组四段的白云岩当中。通过对成矿的地址背景和矿体地质遗迹古地理位置和古气候进行研究,提出了变质重结晶和热液改变为辅的矿床成因模式进行详细分析。To a certain extent, Liaoning Province is rich in mineral resources. With the continuous development of social economy in Liaoning Province, a considerable number of mineral resources have been exploited and utilized. Magnesium deposits in northern Liaoning are located in the southeastern margin of the Fanhe rift in Neoproterozoic and the northern margin of the Qingyuan craton, mainly composed of multiple ore bodies. The magnesite deposit is endowed with dolomite in the fourth member of the Great Wall System higher than the Zhuanghe Formation in the Mesoproterozoic. Based on the study of metallogenic site background, ore body geological relics, palaeogeographic location and palaeoclimate, the genetic model of ore deposits with metamorphic recrystallization and hydrothermal alteration as supplementary factors is proposed for detailed analysis.
