Course Description

Overview

Explore the complexities of reconstructing palaeogeographies in tropical climates through a comprehensive 58-minute lecture focusing on Southeast Asia. Delve into the challenges posed by poor exposure and heavily weathered outcrops in regions like Indonesia and Malaysia. Learn how combining light minerals, heavy minerals, and detrital grain age analyses can fill gaps in geological understanding. Examine the tectonic assembly of SE Asia, including continental blocks, arc volcanism, and plate convergence. Investigate sedimentation history, mountainous rivers, and estimated sediment yields, with a specific example from the Salin Sub-basin in Myanmar. Study various databases and methodologies, including light and heavy mineral analyses, Gazzi-Dickinson models, U-Pb zircon dating, and foraminiferal studies. Discover how these diverse data sets contribute to reconstructing Eocene palaeogeographies and resolving complex tectonic histories in tropical regions.
