The Gua Musang Group: A newly proposed stratigraphic unit for the Permo-Triassic sequence of Northern Central Belt, Peninsular Malaysi

Abstract

The close association between the Gua Musang formation, Telong formation, Aring Formation, and Nilam marble reflect the lateral facies changes among these formations. Poorly delineated boundaries between each formation calls for a reassessment on the genetic and stratigraphic correlation of these formations. The newly proposed Gua Musang Group is defined as argillite-carbonate-volcanic deposited within the same Gua Musang platform during Permo-Triassic period, which includes all four formations under study. High resolution stratigraphy is needed for each formation for better stratigraphic correlation between the various lithostratigraphic units of the Gua Musang Group and other chronologically related rock formations in the region.The new division of formations within this Group is proposed based on lithologies and stratigraphic correlation that could provide better understanding on the geology of northern section of Central Belt of Peninsular Malaysia.

Impact of Paleosalinity, Paleoredox, Paleoproductivity/Preservation on the Organic Matter Enrichment in Black Shales from Triassic Turbidites of Semanggol Basin, Peninsular Malaysia

“…The perturbation in the redox condition was associated with the depositional condition of Triassic turbidites, which was tectonically controlled. During the Middle Triassic times, due to basin segmentation, thermally driven uplift and subsidence linked to Sukhothai Arc likely played a vital role in the sea level fluctuation during deposition [75,76]. This volcanic (tectonic)-controlled agitation observed throughout the deposition of Semanggol turbidite deposits greatly influenced the relative sea level in the Semanggol Basin, which triggered sporadic shallowing and deepening events.…”

“…During the Late Triassic, due to segmentation and intensified subsidence of the Gua Kodiang-Semanggol Basin, a gradual deepening of the sea level occurred towards the western side, and the depositional environment shifted from oxic to anoxic in the deeper parts of the basin, establishing favorable conditions for organic matter accumulation (Figure 11). The eastern side of the Semanggol Basin was dominated by shallow water facies like conglomerate-sandstone, which were deposited under high-energy conditions due to progressive regression during the last stage of the Indosinian Orogeny, and deposition took place in the oxic water column [20,75]. On the contrary, a negative correlation (Figure 10E) is observed between both elements as increased Mo concentrations were accompanied by constant low Cd concentrations, indicating a strong upwelling environment (Figure 10D).…”

Weight of Evidence Spatial Quantification of Gold Mineral Systems Components in Southern Part of Kelantan

“…The sedimentary Formation has been identified and referred to as Gua Musang Formation which is considered part of the central gold belt of Malaysia. Mohamed et al [10] recently described Gua Musang Formation as a Middle Permian-Upper Triassic age sedimentary Formation. The Gua Musang Formation is comprising of mainly three members; (i) argillaceous facies, mudstone, and pelitic hornfel, (ii) slate and phyllite, (iii) sandstone and metasandstone rocks.…”

Geological heritage as a basis for geoscience development: A case study of Bentong-Raub Suture in Lojing District, Gua Musang District, Kelantan, Malaysia

“…Peninsular Malaysia is one of the essential parts of the Southeast Asian continental core that makes up Sundaland. Sivmastelane and Sukhothai Arc, which make up its two structural components, can be separated into three North-South belts in the west, center, and east [6], [7], [8].…”
