On the basis of detailed studies of the sections of the bauxitedeposits, the genetic types of minerals, the hydrogen and oxygen stable isotopic composition of diaspore andcompositions of parent materials, the writer has revealed that Early Carboniferous laterization was the mainmineralizing stage of the bauxite, and the various mineralizing processes dominated by desilication andiron-separation created an excellent time-space environment for the formation of the bauxite.展开更多
文摘The bauxite in northern Guizhou is shown by its unique palaeokarst forms and weathering textures andstructures to be of palaeokarst-weathering origin. On the basis of detailed studies of the sections of the bauxitedeposits, the genetic types of minerals, the hydrogen and oxygen stable isotopic composition of diaspore andcompositions of parent materials, the writer has revealed that Early Carboniferous laterization was the mainmineralizing stage of the bauxite, and the various mineralizing processes dominated by desilication andiron-separation created an excellent time-space environment for the formation of the bauxite.
