【摘要】 河南登封大冶铝土矿床晚石炭世岩相古地理沉积环境为,古岛高地之间的奥陶纪中期大海退,在碳酸盐岩长达一亿六千万年风化剥蚀的侵蚀面上发育了钙红土铁、铝、硅风化壳。风化壳早期是远离海洋的堆积环境,到铝土矿成形的后期,沉积特征越来越明显,层状构造越来越发育,海侵越来越近,形成滨岸湖泊,甚至浅滩沼泽相沉积环境。这就是晚石炭世本溪期岩相规律,至太原期海侵、海退反复活动形成一系列海陆交互相的复理石沉积建造,由此将早期形成的铝土矿完整保存下来至今。实质上铝土矿的岩相分布规律就是地壳升降运动的间接产物。更多还原

【Abstract】 Late Carboniferous lithofacies paleogeography Sedimentary environment of Daye bauxite deposit in Henan Dengfeng is the mid - Ordovician sea retreat between the ancient island highlands.For more than one hundred and sixty million years has developed in carbonate rock weathering and denudation of the erosion of surface calcium clay iron,aluminum,silicon weathering crust.Early is in weathering crust the depositional environment far from the sea,To the late period of bauxite formation,the characteristics of sedimentary, became more and more obvious,layered structure developed,transgression became increasingly close,form the shore lake,or even shallow swamp facies sedimentary environment.This is lithofacies of Benxi stage in the Late Carboniferous period,to Taiyuan during transgressions and regressive repeated activities form a series of sea - land cross flysch sedimentary formation,the early formation of the bauxite preserved completely up to now.In essence,the facies distribution of bauxite is the indirect result of vertical crust movement.更多还原
