Identifying the link between lineament and cave passage trends to comprehend fractures continuity and influence on the Kinta Valley karst system, Peninsular Malaysia

The Kinta Valley karst landscape is characterised by residual limestone hills scattered all over the valley. The aim of this study is to ascertain the link between lineament and cave passage orientations, and to identify the main fracture controlling the karst features. To achieve that, standard c...
