GEOLOGICAL CHARACTERISTICS OF THE SHALLOW OREBODY IN THE WACHANGPING BAUXITE DEPOSIT IN GUIZHOU PROVINCE

The Wachangping bauxite deposit is located in the Wuchuan-Zhengan-Daozhen bauxite metallogenic belt in Northern Guizhou Province, which belongs to middle mountain landform with intense dissection. The shallow orebody is on the eastern wing of the Luchi syncline between No. 7 and No. 17 exploration lines, with a length of 1000 m along the strike and 110-187 m in the direction of dip. The ore occurs in the Middle Permian Liangshan Formation, overlaid by the carbonate rock mountain body. The orebody is in bed form, in consistent occurrence with the wallrocks, with 2.55 m in average vertical thickness, 0-187 m in buried depth and 11-26° in dipping angle. The faults F1 and F2 enter and evanesce in the orebody.
