“…Borneo is associated with tectonic subduction coupled with obduction of ophiolites and closure of palaeo‐basins (Hall, 2013; Mathew et al, 2014; Ramkumar et al, 2021; Siddiqui et al, 2019; Usman et al, 2021; Usman, Siddiqui, Mathew, et al, 2020). The northern part of Borneo is comprised of the Sabah Basin (Figure 1a), which was filled by the Late Cretaceous to Tertiary sediments (Jamil, Siddiqui, Ahmed, et al, 2021; Siddiqui et al, 2020). Tectonically, the Sabah Basin lies at a complex geological junction between the Sunda Sea, Celebes Sea, Sulu Sea, and the South China Sea, the closure of which resulted in the Sabah orogenic belt (Figure 1) (Hall, 2013; Murtaza et al, 2018; Ramkumar et al, 2018; Suggate & Hall, 2014; Usman, Siddiqui, Mathew, et al, 2020).…”
