鲁奎山铁矿成因探讨

摘要

Lukui Hill iron ore is a type of siderite deposits that located in central Yunnan Kunyang Early Proterozoic rift, situated at the southern section of Kangdian axis, and hosted in Dalongkou Formation of Kunyang Group. It deposited in the zebra limestone in the top of Dalongkou Formation, bedded distribution stratabound obvious. This type of ore is the largest iron ore group have proven in Kunyang Group now, accounting for more than 20% of proven iron ore in Yunnan Province. This paper analysed the regional structure, deposit geology and ore-controlling factors of Lukui Hill iron ore. It provides a basis for better exploitation of such iron ore.%鲁奎山铁矿为分布于滇中地区中元古代早期昆阳裂谷中，位于康滇地轴南段，赋存于昆阳群大龙组的菱铁矿床。铁矿产于大龙口组底部条带状灰岩中，呈似层状分布，层控明显。该类型铁矿为目前已探明的昆阳群中最大的铁矿，占云南省内已探明铁矿的20%以上。本文通过对鲁奎山铁矿的区域构造、矿床地质、控矿因素的分析，确定矿床成因，为更好的开发利用此类铁矿提供基础。
