SEDIMENTOLOGY AND PETROGRAPHIC STUDIES OF WEST CROCKER FORMATION IN SULAMAN AREA, KOTA KINABALU, SABAH.

In this paper, the author describes the sedimentology and petrography of West Crocker Formation in Sulaman area, Kota Kinabalu, Sabah. West Crocker Formation is part of the accretionary complex in NW Sabah. The beddings are almost vertical and the sediments are all clastic. The facies in West Crocker Formation could be divided into four main groups; i) massive sandstone, ii) silty sandstone, iii) laminated mudstone, ix) carbonaceous shale. The contact between facies shows two main current trends which are strong turbidity current and weak turbidity current.
