摘要
通过近几年的地质找矿工作,莱州市土山—东宋地区发现了中型变质沉积铁矿床。矿床产于古元古代粉子山群小宋组二段底部的含铁岩系。矿石工业类型为需选弱磁性铁矿石,主要成因类型为磁铁黑云片岩型、磁铁变粒岩型。矿床范围内共划分了5个矿段40个矿体。该文以此为基础,对矿区地质特征进行分析研究,以期促进山东省铁矿地质勘查工作的开展。
in recent years,through geological prospecting work,medium sedimentary metamorphic iron deposit has been found in Tushan-Dongsong area in Laizhou city.The deposit occurred in the strata of Fenzishan group,and controlled by iron-bearing rock at the bottom of second section of Xiaosong formation.Its industrial types of ore bodies are weak magnetic type which should be chosen.Its ore-forming types are magnetic biotite schist and magnetic granulite type.Five ore sections and 40 ore bodies have been circled within the scope of the deposit.On these basis,geological characteristics of this mine area are analyzed which will promote geological exploration and iron ore prospecting work.
