大冶铁山矿床,产于铁山侵入体南缘中部与三叠系大冶群大理岩的接触带附近。过去认为是典型的接触交代型矽卡岩铁（铜）矿床,通称为“大冶式铁矿”。近年来我们配合鄂东铁矿科研组,在野外观察基础上,对大冶铁山矿床的岩浆岩、矿体、主要近矿围岩分别进行了系统的包裹体镜下鉴定和均一法测温,并对部分典型矿石作了爆裂法测温和包裹体成份分析。本文将着重从包裹体研究出发来探讨大冶铁山矿床的某些成因问题。
The Daye-Tieshan deposit is produced near the contact zone between the middle margin of the southern margin of the Tieshan intrusion and the marble of the Daye Group in the Triassic. In the past, it was considered as a typical contact contact type skarn iron (copper) deposit, commonly known as “Daye iron ore.” In recent years, we cooperate with the research group of East Hubei Iron Ore, on the basis of field observation, we systematically identified and homogenized the magmatic rocks, ore bodies and main ore rocks in the Daye-Tieshan deposit , And some typical ore blasting temperature and inclusion analysis. This article will focus on the study of inclusions to explore some of the genetic causes of Daye Tieshan deposit.
