GEOMORPHOLOGY AND KARSTIFICATION OF CARBONATE BUILD-UP IN CENTRAL LUCONIA PROVINCE, OFFSHORE SARAWAK

The advances in karsts have revolved on the studies of onshore outcrops, high-resolution multi-beam survey, and seismic. The research project aims to study the karstic morphology from a seismic viewpoint. The seismic data was provided by PETRONAS acquired over the Luconia shoals, offshore Sarawak. T...

The research project aims to study the karstic morphology from a seismic viewpoint. The seismic data was provided by PETRONAS acquired over the Luconia shoals, offshore Sarawak. The carbonate platforms located over the shoals were developed over a rather tectonically active setting over a pre-rifted continental crust.
