Upper Cretaceous-Upper Eocene mud-dominated turbidites of the Belaga Formation, Sarawak (Malaysia): 30Ma of paleogeographic, paleoclimate and tectonic stability in Sundaland

Subduction history of the Proto-South China Sea: Evidence from the Cretaceous - Miocene strata records of Borneo

“…5). The results are roughly consistent with the calculated results of deposition and denudation of Zhu et al (2021). Geochemical data from Late Cretaceous -Miocene sedimentary strata in Borneo were collected to examine their provenance.…”

Geochemistry and paleogeography of the Rajang Group, Northwest Borneo, Malaysia

“…While Hutchison (1996) suggested that the whole of the Rajang Group represents the accretionary prism formed by subduction of ancient oceanic crust. Two recent studies have mapped the tectonic background based on major and trace elements of the Rajang Group: The tectonic background discriminant diagrams based on major elements show passive continental margin signals, while trace elements show the opposite (Ahmed et al, 2020;Baioumy et al, 2021). The chemical index of alteration (CIA) (Nesbitt and Young, 1982;Fedo et al, 1995) plot indicates the sampled rocks are in the advanced stages of weathering, with K enrichment by diagenesis during burial (Nesbitt and Young, 1982) (Fig.…”
