广西新生代以来,处亚热带气候区,风化作用强烈,风化矿床甚为发育,具有重要的经济价值。在全国久负盛名的广西锰矿,风化矿床约占36.4%。广西重要的有色金属之一的铝土矿,风化矿床占87.9%。广西出口矿产品钛砂矿,风化矿床占81.9%。在广西矿产中占重要位置的稀土,稀有金属和高岭土矿,几乎全是风化矿床。这里仅介绍锰、铝、钛砂等的风化矿床以供研究。一、广西风化锰矿床(氧化锰矿床)广西沉积岩有13个含锰层位,主要产在台沟相和盆地相沉积物中。以晚古生界最盛。海
Since the Cenozoic in Guangxi, the subtropical climate zone has a strong weathering effect and the weathered deposit is quite developed with important economic value. In the country’s prestigious Guangxi manganese ore, weathered deposits account for about 36.4%. Guangxi is one of the important non-ferrous metal bauxite, weathering deposits accounted for 87.9%. Guangxi exports of titanium ore minerals, weathering deposits accounted for 81.9%. Rare earths, rare metals and kaolinite, which occupy an important place in Guangxi’s mineral resources, are almost all weathered deposits. Only the weathering deposits of manganese, aluminum and titanium sand are introduced for research. I. Guangxi Weathered Manganese Deposit (Manganese Oxide Deposit) There are 13 manganese-bearing beds in Guangxi sedimentary rock, which are mainly produced in the sediments of the Taiwan Dagou and the basin. To the late Paleozoic peak. sea
