鲁东地区白垩纪早期非金属矿含矿火山－沉积建造

ORE-BEARING VOLCANIC-SEDIMENTARY FORMATION OF NONMETALLIC MINERALS IN THE EARLY CRETACEOUS PERIOD IN EASTERN SHANDONG

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。

Abstract:

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...
