山东峨山玻璃用石英砂岩矿地质特征及成因分析

摘要

峨山玻璃用石英砂岩矿床赋存于寒武纪长清群李官组地层中，呈层状产出，共1个矿层，由于区内褶皱构造发育和长期的风化剥蚀，被分割为5个矿体。矿石质量较好，无夹层；矿床平均组分SiO296．46％，Al2O30．84％， Fe2 O30．21％，矿石质量优良。矿床属层控的滨海陆源碎屑沉积矿床。%Glass used quartz sandstone in Ershan area occurred in Liguan group of Cambrian Changqing group with layer type. It has one layer. Due to the folding structure development and long term weathering and denudation, it has been divided into 5 ore bodies. Ore quality is good without interlayer. Its average components are as follows:SiO2 is 96.46%, Al2 O3 is 0.84% and Fe2 O3 is 0.21%. Ore quality is good. The deposit belongs to stratabound lit-toral terrigenous clastic sedimentary deposit.
