摘要
我国铝土矿已知有本溪组、龙潭组、大塘组、全新统、太原组等11个含矿层位,华北成矿区、黔鄂成矿区、滇桂成矿区等11个成矿区带,其形成机理与红土化及铝土矿化有关,直接受古湿热气候、构造长期稳定、准平原化、排水条件好、沉积间断时间长及沉积环境、古地形地貌、地质构造、次生改造等影响.
China's bauxite Ores are known to cccur in 11 ore-bearing horizons (including Benxi, Longtan, Datang, Taiyuan Formations, Holocene series, etc.) and 11 metalloginic provinces (belts)as the NorthChina. Qian-E. Dian-Gui, etc. Their ore-forming mechanism isrelated to laterization and bauxitization.They were formed in a favourable condition represented by humid palaeoclimate, long-termed stable tertonic environment, peneplainization, well-developed drainage system and long sedimentary interval,and controlled by sedimentary environment, palaeotopography-palaeogeomorphology, geological structureand secondary modification.
