摘要
山东是我国非金属矿较多的省份,发育着多种非属周矿产.这些非金属矿产均产在一定的含矿建造中,而这些非金属矿含矿建造的形成和分布是存在着明显规律性的.第一,在鲁西地体、胶北地体和胶南地体的每个地体构造单元中.发育着各具特点的非金属矿含矿建造和非金属矿产,每一个地体均具有独特的非全属矿成矿专属性;第二,在山东地壳演化的陆核形成阶段、陆块发展阶段、陆缘发展阶段和滨太平洋发展阶段的每一个地质历史发展阶段中,形成了不同的非金属矿含矿建造,控制了山东各类非金属矿产的形成和时空分布,其为山东非金属矿产的四个大的成矿期。依据非金周矿合矿建造划分原则,据目前已有资料,在山东省内共划分出35种非金周矿含矿建造。
Shandong is a large province rich in a variety of nonmetallic minerals. They occur incertain specisl ore-bearing formations which have been formed and distributed regularly.First, unique nonmetallic minerals and ore-bearing formations are developed in eachtectonic units of the Luxi, Jiaobei and Jiaonan terrains. Second, different types ofnonmetallic mineral-bearing formations were developed during different stages in thegeological history, including the continental neucles'forming stage, the continental blockdevelopment stage,the continental margin development stage and the circum-Pacific zonedevelopment stage of the crustsl evolution of Shandong. These are four major ore-formingperiods and have controlled the formation of various nonmetallic minerals and their spatialand temporal distribution.According to the classifiottion criterta of nonmetailic mineral-bearing formations andsome materials at hand, 35 nonmetallic mineral-bearing formatiosn are classified inShandong Province.
