| 摘 要： | 牛泉铁矿位于鲁西地块莱芜铁矿集区内,是一个较为典型的“邯邢式”矽卡岩铁矿。前人对莱芜铁矿集区张家洼铁矿研究报道较多,但鲜有人对其西南5km处的牛泉铁矿进行研究。本文在前人勘查工作基础上介绍了牛泉铁矿成矿地质背景,从地层、岩浆岩、矿体特征、矿石特征、围岩蚀变等方面详细介绍了矿床地质特征、划分了成矿期次、初步探讨了成矿时代和矿床成因。牛泉铁矿形成于早白垩世,与中生代侵入岩矿山岩体关系密切,属于克拉通破坏的产物。

| Abstract: | Niuquan iron deposit is located in Laiwu iron ore concentration area in Luxi block. It is a typical "Hanxing type" skarn iron deposit. There are many reports about Zhangjiawa iron deposit in Laiwu iron ore concentration area, but few people have studied Niuquan iron deposit 5km southwest of it. Based on previous exploration work, metallogenic geological background of Niuquan iron deposit has been introduced. Geological characteristics of the deposit has been introduced in detail from the strata, magmatic rocks, ore body characteristics, ore characteristics, wall rock alteration and other aspects. Metallogenic stages have been divided, and metallogenic age and origin of the deposit have been discussed preliminarily. Niuquan iron deposit was formed in early Cretaceous, which is closely related to Mesozoic intrusive rock and mine rock mass, and belongs to the product of craton destruction. |
