GSM Technical talk (in collaboration with the Geology Dept. UM): “Basin physiographic controls on shoreline–shelf sedimentary processes and preservation: Integrating numerical tidal modelling and sedimentary facies analysis in the Oligo–Miocene, NW Borneo, South China Sea” - Daniel S. Collins, PhD (Geological Survey of Japan)

Event Code : GSMTT 09-12-2018 Venue Name : Geology Department, University of Malaya Host Name : Coordinator Name : Date From : 2018-09-12

This talk begins at 5pm. Refreshments will be provided in the Museum at 4:30pm.

Abstract:

Shoreline–shelf stratigraphy is an inherently fragmentary record of competing fluvial, tidal, wave and storm processes, and longer-term controls on accommodation space creation, burial and erosion. These controls are influenced by a multitude of regional- to local-scale factors fundamentally related to plate tectonics, principally climate and basin physiography (depth and geometry), which are encapsulated in time-averaged palaeogeographic reconstructions. This talk investigates the following:

• Utility of numerical palaeotidal modelling for assessing the impact of palaeogeographic changes and uncertainty on tidal processes in the Oligo–Miocene of Southeast Asia.
• Comparison of tidal model results to sedimentary facies and biostratigraphic data from Oligo–Miocene successions in and around the South China Sea
• Sedimentological and stratigraphic characteristics and preservation in mixed-process deltaic successions in the Middle Miocene Baram Delta Province, Northwest Borneo
• Potential impact of evolving tidal systems on mangrove-related carbon burial in the Oligo–Miocene of Southeast Asia.
