登封市密腊山玻璃用石英岩矿地质特征及成因浅析

Geological Characteristics and Genesis Analysis of Glass Quartz Rock Deposit in Milashan Dengfeng City

登封市密腊山玻璃用石英岩矿属中朝准地台南缘嵩箕台隆区,区内构造较为复杂,具双层结构,矿体赋存于嵩山群罗汉洞组二段地层中,矿体厚度呈有规律变化,矿石质量较好、较稳定,为一较优质玻璃用石英岩矿床。本区石英岩矿床受地层、构造双重控制,即受下元古界嵩山群罗汉洞组二段的石英岩控制,又受密腊山向斜控制,矿床成因类型是沉积变质型石英岩矿床。矿区深部及南北方向外围有较好的玻璃用石英岩矿成矿远景,有较大找矿潜力。

The glass quartzite mine in Milashan,Dengfeng city,belongs to Songjitai uplift area on the southern edge of the Sino Korean paraplatform.The structure in the area is relatively complex,with a double-layer structure.The ore body occurs in the second member of the Luohantong formation of the Songshan group.The thickness of the ore body changes regularly,and the ore quality is good and stable.It is a high-quality glass quartzite deposit.The quartzite deposit in this area is controlled by both stratum and structure,that is,by the quartzite of the second member of Luohandong formation of Songshan group in the Lower Proterozoic,and by the Mila mountain syncline.The genetic type of the deposit is sedimentary metamorphic quartzite deposit.The deep and northsouth periphery of the mining area have good prospects for the mineralization of glassy quartzite deposits,with great potential for mineral exploration.
