RELATIONSHIP BETWEEN KARST DEVELOPMENT, COLLAPSE SINKHOLES, & FAULT TRENDS TO DEVELOP THE FIRST CENTRAL LUCONIA'S CARBONATE KARST ISLAND MODEL

Summary he paper focuses on the relationship among the karst collapse sinkholes, extensional fault trends, and associated offset talus debris observed on several Miocene carbonate platforms of Central Luconia, Sarawak. The Central Luconia province is divided into several tectonic highs i.e. Mega Platform, G Fields High, Bunga Pelaga High, and Southern Field High. The carbonate platforms studied for the analysis are carbonate platforms located on the Bunga Pelaga High. As of now, there have been no in-depth studies concentrating on establishing the first Central Luconia’s Carbonate Karst Island Model. Each of these carbonate platforms actually creates the ideal background platform to further analyse the aforesaid carbonate island karst model. Sea-level changes are a critical factor that influences the distribution and the density of the karst formation. The type of karst features formed on a carbonate platform is also influenced by the rise and fall of the sea-level because these changes of sea-level will influence the period of exposure which in turn, will determine the duration of Stillstands that is needed to create the karst features. Therefore, to further analyse these carbonate platforms, results of this analysis will help construct the carbonate karst island model for the Bunga Pelaga High carbonate platforms.
