摘要:In its 26 years of existence, the journal of Natural Resources Research (NRR) has published and continues to publish papers on geochemical anomaly and mineral potential mapping. This is consistent with its aims and scope to publish quantitative studies of natural (mainly but...

摘要:According to previous studies, the use of enrichment factors in environmental studies is inconsistent with its original concept and that such indiscriminate use of enrichment factors should be stopped. In this contribution, it is shown through spatial correlation analysis that us...

摘要:In this study, stream sediment geochemical data have been subjected to robust principal components analysis (RPCA) and singularity mapping (SM) to enhance and map significant multivariate geochemical anomalies (i.e., mineralization-related) in Ahar area, NW Iran. The RPCA wa...

摘要:Abstract Whereas the mechanism of fluid flow, and thus structural control, linked with mineral deposit formation is quite understood, the specific structures that likely provided controls on mineralization at certain geographic scales are not readily known for a given region...

摘要:Abstract(#br)The genesis of mesothermal Au-quartz vein deposits, which are among the more economically important type of Au deposits, is still under debate. There are two main theories, proposed in the literature, for the subsequent formation of these deposits in suitable structu...

摘要:Abstract(#br)The East Kunlun Orogenic Belt (EKOB) played an important role in plate tectonics, magma generation, and crustal evolution. Late Triassic granodiorites and their mafic micro-granular enclaves (MMEs) from Xiao-Nuomuhong in the EKOB were studied for geochemistry an...

摘要:Abstract(#br)The subduction and collision tectonics in the Sanjiang region provide important insights into the evolution of the Paleo-Tethyan Orogen. Here we present LA-ICP-MS zircon U–Pb ages, Sm–Nd and Lu–Hf isotopic data, whole-rock major and trace element compositio...

摘要:Abstract(#br)Recent investigations have revealed several large Au and Mo deposits in the Xiong’ershan region, Central China. Most quartz porphyries associated with the mineralization occur as dikes and apophyses, or as rubbles cemented in mineralized breccia pipes. Three typ...

摘要:Abstract(#br)The Shuangwang gold deposit (with a gold resource of approximately 70 t Au), hosted in a NW-trending breccia belt, is located in the Fenxian-Taibai fore-arc basin in the West Qinling Orogen of central China. Four stages of ore paragenesis are identified, demonst...
