| Abstract: | Houcao bauxite mine is located at the central part of Zunyi bauxite ore belt in the central Guizhou province.The mining area is controlled by a karst basin.Here are developed various morphological karst features,such as medium-small karst depression,pit and gully.In the depressions is deposited the Al-bearing rock sequence of Jiujialu formation of Lower Carboniferous Series.354 drill holes were operated in Houcao area to control thickness of the Al-bearing sequence.Statistics of of the thickness and chemical composition of the rock were made to study the paleo-karst morphology control on the bauxite ore.Based on the control prospecting targets are predicted.The Al-bearing sequence is strictly controlled by paleo-erosion surface and occurrence and thickness of the Al-bearing sequence directly by the paleo-karst morphology.In the paleo-karst depression the Al-bearing sequence is relatively thick and w(Al2O3) higher.At the convex the sequence gets thinner and no bauxite ore occur.At the gentle relief without paleo-karst erosion the sequence is stable in thickness and single occurrences.The bauxite ore looks layered or layeroid.In areas in south of Saba and Houcao village distinct paleo-karst morphology occur and the Al-bearing sequence thicker thus worth prospecting. |
