Facies Analysis and Sedimentary Architecture of Hybrid Event Beds in Submarine Lobes: Insights from the Crocker Fan, NW Borneo, Malaysia

Hybrid event beds represent the combined effect of multiple geological processes, which result in complex depositional geometries and distinct facies distribution marine environments. Previous work on hybrid highlights classification, origin, types facies. However, present study, we discuss development submarine lobes with an emphasis analysis proximal to distal, frontal lateral relationships evolution during lobe progradation. Detailed fieldwork was carried out classical deep-marine Late Paleogene Crocker Fan understand relationship between character bed architecture. The results indicate that massive or structureless sandstone mud clasts, clean muddy sand, chaotic sand oversized patch alternations (H1–H3) are well developed medial lobes, while distal mainly contain parallel cross-laminated (H3–H5). Furthermore, have less vertical thickness than lobes. takes place lower part thickening upward sequence progradation, retrogradation contains intervals upper stratigraphy.
