Taking bauxite deposits in northern Guizhou as an example, this paper deals with the mechanism of bean-pebble texture of palaeokarst bauxite deposits. The existence of bean-pebble texture showed that the bean-pebble grains has undergone a period of soil-redding or that they were originated directly from red soil materials. When chemical weathering action occurred in the acid leaching period, a lot of organic aci...             铝土矿床中豆鲕粒结构的形成,直接与红土化作用有关.本文试以黔北铝土矿床为例,论述了古代喀斯特型铝土矿床中豆鲕结构的成因机理。其豆鲕粒结构存在的本身便标志着经历了红土化阶段或直接源出于红土物质。当化学风化作用进入到酸性淋溶阶段时,大量的有机酸胶、铝、硅、铁胶,经过复杂的分凝、软胶化、扩散、间歇反应、陈化等胶体化学作用,直接孕育成了豆鲕粒结构.豆鲕粒的形状、大小、密度、分布等特征,则取决于原始溶胶的数量、浓度,浓度梯度和相对稳定度。与豆鲕粒结构密切伴生的复胶状结构,其成因也是胶体作用所致.属风化作用或与风化作用密切有关的矿床类型. 文摘来源   << 更多相关文摘         相关查询: 淋溶酸性土 酸性 淋溶 酸性泥炭土 酸性溶剂 酸性磷酸化酶 酸性核糖核酸酶 酸性溶液 酸性腐殖化 酸性脱氧核糖核酸酶 酸性熔岩 酸性树脂  对查询结果不满意
