摘　　要：鲁东地区白垩纪早期火山沉积作用形成了一套火山－沉积岩系和膨润土、沸石岩、珍珠岩、明矾石、黄铁矿、玄武岩等非金属矿含矿火山－沉积建造。主要有含膨润土、佛石岩、珍珠岩酸性熔岩－火山碎屑岩建造，含明矾石中酸性凝灰岩建造，含黄铁矿中性火山碎屑岩建造等。鲁东地区白垩纪早期这些非金属矿的形成，明显受控于大地构造背景、火山活动旋回及岩石物理化学条件、温度压力条件及水介质条件等。Due to the volcanic-sedimentary process in the early cretaceous period in eastern Shandong, a set of volcanic-sedimentary rocks and nonmetallic mineral-bearing volcanicsedimentary formations, containing bentonite, zeolite, perlite, alunite, pyite and basalt wereformed. They are mainly acid lava-pyroclastic rock formation with bentonite,zeolite and Perlite, intermedtale-acid tuff formation with alunite and intermediate pyroclastic rockfomation with pyrite. The nonmetallic mineral deposits of early Cretaceous age in easternShandong are clearly controlled by geotectonic, volcanic activity cycle, rock's physical andchemical properties, P-T and aqueous medium conditiones.
