Sedimentology and stratigraphic architecture of syn-rift alluvial fan conglomerates in Nam-phrae, Chiang Mai basin
Main Article Content
Abstract
This study focuses on an exposed outcrop of an alluvial fan. It is comprised of footwall conglomerates in Nam Phrae syn-rift within the larger intracratonic Chiang Mai basin. Its lithofacies architecture and stratigraphy is a product of the interactions of deBris flow, over bank deposits, sheetflood flows and braided channel depositional mechanism in conjunction with allocyclic and autocyclic controls changing with time. By using a lithofacies correlation model, the complex stratigraphy is revealed to show its three dimensional geometry and its relation to the overall basin in terms of its hydrocarbon reservoir potential.
