山东省陶瓷土（瓷石）矿资源特征及成矿规律

Characteristics and Mineralization Regularity of Ceramic Soil（Chinastone） Resources in Shandong Province

摘要:

山东省陶瓷土（瓷石）矿区共27个，查明资源储量49316.80万t，占全国总量的25.54%，排名第二。山东省岩浆型陶瓷土（瓷石）矿床原岩主要为燕山期浅成花岗斑岩、石英斑岩、细晶岩及霏细岩岩脉、岩盖。火山沉积型陶瓷土（瓷石）矿床原岩主要为早白垩世青山群石前庄组陆相火山岩系中的酸性-中酸性流纹质玻璃质火山碎屑岩和玻璃质熔岩。瓷石矿体与酸性花岗（斑）岩脉紧密相关，蚀变花岗（斑）岩是寻找瓷石的直接标志。

Abstract:

There are 27 ceramic clay (chinastone) mining areas in Shandong province. The reserves of resources are 49316.8 ten thousand tons，accounting for 25.54% of the identified reserves and ranking the second in China. The protolith of magmatic ceramic earth (porcelain stone) deposit in Shandong province are mainly rock veins and rock caps of Yanshanian shallow granite porphyry, quartz porphyry, fine-grained rock and feldspar. The protoliths of the volcanic-sedimentary ceramics clay (porcelain stone) deposit are mainly acid-intermediate acid rhyolitic vitreoclastic rocks and vitreous lavas in the continental volcanic rock series of Shiqianzhuang formation of Early Cretaceous Qingshan group. Porcelain ore bodies are closely related to acid granite (porphyry) dikes, and altered granite (porphyry) rocks are the direct indicators of looking for porphyry.
