摘要
红舍克铝土矿由沉积型及风化堆积型二类。沉积型铝土矿由越北古陆中的岩浆岩、变质岩经长期剥蚀、风化后,经长距离搬运沉积而成,受基底、古岩溶地貌、沉积环境和沉积相的控制。堆积矿床属于表生第四纪岩溶堆积型,不但与岩性、气候、构造、地形地貌关系密切,亦与沉积型矿床有直接因果联系。
The Hongsheke boxites deposit can be divided into the boxites deposit of sedimentary type and weathering accumulation type.The former is formed by the long term denudation-weathering and long distance transportation of magmatic and metamorphic rocks on the North Vietnam Oldland,which is controlled by the basement,palaeokarst,sedimentary environment and facies.The latter belongs to the Quaternary epigenetic karst accumulation ore deposit,which is not only in close relation with the lithologic character,climate,tectonics,topography and geomorphology,but also in direct genesis relation to the sedimentary ore deposit.
