“…In nearby Malaysia, Fauzi et al (2019) and Setiady and Aryanto (2009) identified REE prospects in placer deposits derived from granitic source rocks. Similar studies have been carried out on placer deposits in other areas, such as Kazakhstan (Suiekpayev et al, 2021), Sri Lanka (Batapola et al, 2020), China (Van Gosen et al, 2019), Turkey (Öztürk et al, 2019), Greece (Papadopoulos et al, 2019), the USA (Bern et al, 2016), and Europe (Goodenough et al, 2016). In the southwestern part of Indonesian Kalimantan, the granitoid igneous rocks as well as the metamorphic rocks of the Schwaner Mountains are believed to be the source of placer deposits in the Central Kalimantan Province (Herman, 2007).…”

Massive tailings have resulted from the extensive use of placer deposits in Central Kalimantan, Indonesia, by artisanal and small-scale gold mining (ASGM) activities. Recently, the placer deposits and their tailings have been exploited for heavy minerals. In this study, geochemical and magnetic analyses were carried out on these deposits to identify the prospect of REE (rare earth element) exploration in the materials already collected by ASGM activities. Samples were collected from ten different locations. For each location, two different fractions were prepared for analyses, i.e. the heavy mineral (HM) fraction and the panned (M60) fraction. All HM and M60 samples were subjected to magnetic susceptibility measurements, but only representative samples were subjected to x-ray fluorescence (XRF) measurements (for Si, Ti, Fe, Zr, and Al) and to inductively coupled plasma-emission spectroscopy (ICP-OES) measurements (for Eu, Tb, Dy, and Sc). The results showed that the concentrations of major elements (Ti, Fe, Zr, and Al) vary significantly from deposits along one river to another, while the concentration of Si is rather similar. Compared to M60 samples, the HM samples have higher concentrations of Ti, Fe, Zr, Al, and Sc, implying that the sluice-box separation enhances the concentration of valuable minerals. Magnetic susceptibility is found to be correlated with Fe and Sc concentrations, confirming the potential use of magnetic measurements as a complementary tool for Fe and Sc exploitation in placer deposits. It is believed that both the source rocks and the sedimentary settings of these deposits determine whether certain elements (Sc, Fe, and Zr) are present or absent in Central Kalimantan placer deposits. The prospect of exploring and exploiting Sc in these placer deposits might augment the ASGM activities in Central Kalimantan.

“…Synthesis and analysis of the geological and mineralization data from the Great Altai region open new perspectives on the evolution of major metallogenic structures as a basis for exploration criteria, especially in poorly investigated and buried areas. The mineralization processes, with formation of base, rare, and precious metals and other types of mineral deposits, developed in different tectonic settings in the course of its long history (Table 2) [27,30,[48][49][50]52,61,63,67,[72][73][74][75][76][77][78][79][80].

“…Mineralization developed in weathering profiles upon Paleozoic bedrocks that formed in a wet and warm subtropic climate. They are a nontronite profile of weathered seprenitnized serpentinites, which hosts Belogorsk gold deposits in the West Kalba belt [72,106]; kaolinitesericite weathering profiles in the West Kalba and Zharma-Saur areas, with Zhanan and Mukur gold deposits, respectively [22]; a kaolin profile and sand placers with Satpaev and Karaotkel Zr-Ti deposits in the West Kalba area [78,79].…”

The Great Altai region, located at the boundary of Russia, Mongolia, China, and Kazakhstan, belongs to the system of the Central Asian Orogenic Belt. It has undergone a long complex geological and metallogenic history. Extremely rich resources of base, precious, and rare metals (Fe, Cu, Pb, Zn, Ag, Au, Li, Cs, Ta, Nb, REE, etc.) maintain developed mining and metallurgical industry, especially in East Kazakhstan, which is the key metallogenic province. The East Kazakhstan province comprises the Rudny Altai, Kalba-Narym, West-Kalba, and Zharma-Saur metallogenic belts, each having its typical mineralization profiles and deposits. The reconstructed geodynamic and metallogenic history of the Great Altai province, along with the revealed relationships between tectonic settings and mineralization patterns, allowed us to formulate a number of geodynamic, structural, lithostratigraphic, magmatic, mineralogical, and geochemical criteria for exploration and appraisal of mineral potential in Eastern Kazakhstan. Geodynamic criteria are based on the origin of different mineralization types in certain geodynamic settings during the Late Paleozoic–Early Mesozoic orogenic cycle. Structural criteria mean that the location of base-metal deposits in Rudny Altai, gold deposits in the West Kalba belt, rare and base metals in the Kalba-Narym and Zharma-Saur zones is controlled by faults of different sizes. Lithostratigraphic criteria consist of the relation of orebodies with certain types of sedimentary or volcanic-sedimentary rocks. Magmatic criteria are due to the relation between mineralization types and igneous lithologies. Mineralogical and geochemical criteria include typical minerals and elements that can serve as tracers of mineralization. The joint use of all these criteria will open new avenues in prospecting and exploration at a more advanced level.
