Source and origin of Late Paleozoic dropstones from Peninsular Malaysia: First record of Mississippian glaciogenic deposits of Gondwana in Southeast Asia
This study reports several Late Paleozoic dropstone‐bearing formations in Peninsular Malaysia which were not previously investigated. Additionally, the source, formation mechanisms, and correlation to the global Late Paleozoic Ice Age (LPIA) of these dropstones are discussed. Dropstones occur as sub...

This study reports several Late Paleozoic dropstone‐bearing formations in Peninsular Malaysia which were not previously investigated. Additionally, the source, formation mechanisms, and correlation to the global Late Paleozoic Ice Age (LPIA) of these dropstones are discussed. Dropstones occur as subrounded to rounded single clasts ranging in size from 0.5 to 20 cm, scattered in red mudstone, black shales, sandstones and shales, and are composed of granite, quartzite, and sandstone. Occurrence of dropstones as rounded, single clasts, and soft‐sediment deformation of the host rock with striations in the dropstones suggest a glaciomarine origin. Precambrian basement rocks and Cambrian–Ordovician quartzite and sandstones are the main sources of the dropstones. Dropstones hosted by shallow‐marine sediments are formed by dropping of clasts from icebergs, while, dropstones present in deep‐marine sediments are formed by dropping of clasts from an ice sheet. The oldest glaciomarine rocks of the Rebak and Chepor members (Singa Formation) can be correlated to the Early Carboniferous global glaciation of the LPIA episode of Gondwana.
