Peninsular Malaysia is divided into three belts with the Kinta Valley situated in the center of the Western Belt. The Kinta Valley limestone, which is presumed to be Silurian to Permian in age (Peng, 2009), has been undergoing karstification ever since it was exposed to the surface. Since the valley is bounded by granite ranges, i.e. the Main Range in the east and Kledang Range in the west, the rivers descending from the non-soluble rock profoundly impacted on the development of karst in the area. The extant karst landscape, which constitutes about 2.5 of the Valley area (figure1), clearly illustrates the long term and immense dissolution process.
