山东诸城孟家庄子矿区瓷土（石）矿地质特征与成因分析

Geological Characteristics and Genetic Analysis of China Clay (stone) Deposit in Mengjiazhuangzi Mining Area in Zhucheng City of Shandong Province

摘要:

孟家庄子矿区瓷土（石）矿位于诸城市南10km处。矿区主要出露地层为中生代青山群，总体呈NEE向展布，石前庄组是赋矿层位；构造形式是单斜构造和断裂，节理不发育，局部断裂对矿层有一定的破坏作用；岩浆岩为中生代白垩纪青山期粗安斑岩潜火山岩，侵入于青山群方戈庄组中，对矿层没有影响。矿石自然类型为流纹质凝灰岩、流纹质含角砾凝灰岩，工业类型为瓷土（石）矿。成矿类型为陆相（火山）沉积水解蚀变型瓷土（石）矿。

Abstract:

Mengjiazhuangzi China clay (stone) ore mining area is located in 10km south to Zhucheng city. Main outcropping layers are Mesozoic Qingshan group with the trend of NEE. Shiqianzhuang group is orebearing layers. It was composed of monoclinal structures and faults with undeveloped joints.Regional faults will damage orebearing layers. Magmatic rocks are porphyry and subvolcanic rocks in Mesozoic Cretaceous Qingshan group. The rocks intruded into Fanggezhuang formation of Qingshan group, and had no effect to orebearing layers. Natural ore types are rhyolitic tuff and rhyolitic brecciabearing tuff. The industrial type is China clay ore (stone). Metallogenic types is continental hydrolysis (volcanic) deposit corrosion variant porcelain clay ore (stone).
