Abstract:Spanning three geological tectonic units, Shanxi Province has experienced three tectonic evolution stages, including proplate tectonic, plate tectonic and intracontinental orogeny, eight tectonic cycles, and eight major metallogenic geological events, that led to the formation of more than 2,000 mineral deposits, 135 kinds of minerals, four categories of resources that include energy, metal, nonmetal and water vapor. Based on the classification scheme of solid and non solid mineral deposits in Shanxi, this paper summarizes the spatiotemporal distribution of mineral deposits. It concludes that temporally the mineral resources can be divided into 8 distinct early to late metallogenic stages. Spatially, Shaanxi can be divided into 12 ore rich areas from north to south that are closely related to the major metallogenic events in the geological history. Based on spatiotemporal relationships, the ore deposits are divided into four types: single type, coupling type, superposition type and compound type. The types and sizes of mineral resources in the ore rich areas are generally related to the nature and frequency of metallogenic geological events. The superposed ore deposits have higher prospecting potential than the single ore deposits. This study offormation mechanism and distribution of ore rich areas has significant implications for guiding future geological prospecting.
