“…This complies with other research of SE Asian heavy mineral assemblages, where xenotime and monazite are reported to have originated from Main Range Province granitoids in the Malay Peninsula (Sevastjanova et al 2012). Main Range-type granitoids are widely distributed on the Indonesian Tin Islands (Schwartz et al 1995).…”

“…The third triangle (triangle iii) using ilmenite, topaz and cassiterite as parameters, indicate the origin of minerals from the contact between granitic rocks and the metasediment [4]. Apart from the poor presence monazite, triangle iv shows the minerals originate from the granitic rocks within the metamorphic terrain contact.…”

“…Sevastjanova et al [4], concluded that the heavy mineral assemblage in Peninsular Malaysia and Sumatra is 'immature', although these places are located in the middle of the tropical humid country. As such maturity of the source is not as clearly seen in this tropical area.…”

“…Citing apatite as a common mineral in granite and volcanic rocks, apatite is rarely found in river sediments. This suggests that there is selective dissolution during weathering [4]. Fletcher [5] and Fletcher and Loh [6] stated that cassiterite is a common mineral in the granite of Main Tin Belt Peninsular, but very little found in therivers due to the nature of its high specific gravity (6.9 -7.1) and high deposition rate that resulted in it being deposited near (0.5-1 km) to the source [7][8].…”

Abstract. This paper aims to provide the overview of occurrence, distribution and origin of the heavy minerals in the study area. A total of 45 selected stream sediment heavy mineral concentrate samples were panned using standard dulangs, dried and separated from other light minerals using bromoform. The heavy minerals were separated into different fractions at different amperes using Frantz Isodynamic magnetic separator. Mineral identification was done using binocular microscope augmented by X-ray diffraction analyses. Mineral abundance data were analysed graphically using triangular diagrams to show their origin. Dominant minerals present in the heavy mineral samples collected are ilmenite, cassiterite, tourmaline, zircon, topaz, and magnetite. The less common minerals, present in trace amounts are hematite, xenotime, allanite, monazite, rutile, anatase, leucoxene, chromite, garnet and olivine. Examination of the heavy mineral assemblage shows that they originated from granite batholiths of the Main Range, Changkat Rembian as well as from the metasedimentary rock in the area. The gold flakes present are found together with cassiterite and topaz indicating that gold originates from the mineralized veins contact-metamorphosed metasedimentary rocks. Almost all samples collected contain cassiterite grains in various amounts. From the mineral assemblage, the source of cassiterite originates from the mineralized quartz veins that cut granitic rocks of Main Range, Changkat Rembian as well as the metasedimentary rock in the area. Greisenized veins containing quartz, mica and tourmaline with the presence of wolframite and arsenopyrite also contribute to the presence of cassiterite in this study area.

The Bengal Basin is a well‐known foreland basin that archives the tectonic evolution of the Himalayan and Indo‐Burman Ranges (IBR). The Dupi Tila Formation is the youngest among the stratigraphic successions of the Bengal Basin, which witnessed the last phase of the Himalayan uplift. However, there is still controversy regarding sediment provenances since the Himalayan and IBR are in the late Neogene exhumation stage. In this study, the petrographical and geochemical compositions of the Dupi Tila sandstones from the Lalmai Anticline of the Bengal Basin are examined to infer the source rocks, tectonic settings, palaeoclimate and weathering intensity in provenance areas. The detrital modes and geochemical discriminations, as well as Chondrite‐normalized rare earth elements patterns with enrichment in light rare earth elements and nearly flat heavy rare earth elements and negative Eu anomalies (average Eu/Eu* = 0.77) indicate dominantly felsic source rocks. The geochemical data also suggest that these source rocks in provenance areas were influenced by weak to moderate chemical weathering (chemical index of alteration: 65.64–75.62) and multiple recycling under warm and humid to semi‐humid climatic conditions. The detrital zircon ages show three dominant peaks at ca. 100, 500 and 1000 Ma with minor 1700 Ma. The amount of young zircon grains (<120 Ma) is noticeably higher (~18%) in this Lalmai outcrop compared to the Dupi Tila samples from the Sylhet Trough and Chittagong‐Tripura Fold Belt. Results from integrated zircon geochronology and geochemistry indicate that the detritus are likely derived from a recycled orogen provenance related mainly to active continental margin setting with subordinate influence from passive setting. Therefore, the regionally extensive Himalayan Orogen appears to be the primary sediment source, with additional mixing from the IBR and recycled sediments originating from the Gangdese batholith of the Trans‐Himalaya.
