“…Huangyangling is located in the western part of the Qin-Qi-Kun central orogenic belt and belongs to the Tethys-Himalayan mineralization domain (level I), the Cocosilia-Songpan-Ganzi tectonic mineralization belt (level II), the Lazhulong-Dongyinshan antimony-mercury mineralization belt (level III), and the Lazhulong-Huangyangling antimony mineralization belt (level IV) (Zheng et al, 2015;He et al, 2017;Dong et al, 2023;Li et al, 2023). This region has a long geological history, well-developed fault structures, long-lasting hydrothermal activity, a superior geological background for mineralization (Zheng et al, 2022), and 16 known deposits (occurrences), such as Panshuihe, Wolonggang and Huangyangling.…”

Introduction: China has the world’s largest amount of antimony resources and plays a vital role in the global antimony industry. The Huangyangling area in Xinjiang belongs to the Lazhulong-Huangyangling antimony mineralization belt; this area is rich in antimony ore resources, with potential for discovery of additional ore. This high-elevation mountainous area is located in the northwestern region of the northern Tibetan Plateau, with a harsh natural environment and poor transportation access; thus, the use of traditional geological exploration methods is limited, and remote sensing technology provides unique advantages.Methods: Using Landsat 8 OLI and Gaofen-6 (GF-6) data, we extracted stratigraphic, lithologic and fault information from the study area through information enhancement processing of the images. Based on Landsat 8 OLI, Sentinel-2 and ASTER images and the use of remote sensing image preprocessing and interference information masking, the spectral characteristics of limonite, as well as hydroxyl, carbonate, and silicified alteration minerals were utilized; the characteristics included reflection or absorption in specific spectral bands. The spectral characteristics were then combined with principal component analysis (PCA) and the band ratio method to extract the alteration information for the study area.Results: The stratigraphy and boundaries between stratigraphic and lithologic units extracted in this study were defined, and numerous small faults were identified based on a comparison with 1:250,000 geologic maps. And the overall distribution trends of the indicators of alteration extracted in this study were located along fault zones; additionally, the hydroxyl and carbonate alteration anomalies matched well with known deposits (occurrences). Thus, the alteration information is a good indication of antimony ore bodies. Based on the geological interpretation, alteration information extraction and geochemical exploration data, four prospecting areas were identified.Discussion: The method of extracting geological and hydrothermal alteration information by remote sensing has practical significance because it provides the possibility for geological work and mineral exploration in difficult high-elevation environments.

The Sino–Zambian Cooperation Project has filled the gap in Zambia national‐scale geochemical mapping, providing basic geochemical guarantees for Zambia's basic geology, mineral development, environmental protection, agricultural production and other aspects. This article aims to reveal the distribution characteristics of its rare elements (Li, Be, Nb, Rb, Sr). The median value of Li, Be, Nb, Rb and Sr is 4.94 × 10−6, 0.65 × 10−6, 7.50 × 10−6, 33.00 × 10−6 and 21.90 × 10−6, respectively. The median and average values of the Irumide Belt, Zambezi Belt, Choma‐Kalomo Block and Hook Granite Complex are higher than other tectonic belts, showing that rare elements are enriched in those areas. The distribution of element anomaly areas is mainly related to the distribution characteristics of granite type rare metal mineralization occurrences, and a small number of anomaly areas are controlled by salt lake brine‐type mineralization occurrences. A total of five rare metal geochemical anomalies have been delineated respectively based on the 85% cumulative percentage of rare elements (Li, Be, Nb, Rb, Sr). The metallogenic prospective area delineated based on the comprehensive anomaly area of rare elements will provide an important reference for searching for rare metal deposits in this area.
