Abstract: Sulfur is an important non-metallic mineral and one of the dominant minerals in North China. North China is an important production area of pyrite and natural sulfur with abundant and concentrated sulfur resources. Based on the summary of resource endowment, deposit type, spatial and temporal characteristics, main ore controlling factors and metallogenic evolution, this paper comprehensively analyzes the main characteristics and metallogeny of sulfur deposits in North China. From the perspective of ore genesis, sulfur deposits are classified into five types, including sedimento-metamorphic type, sedimentary type, magmatic hydrothermal type, skarn type and natural sulfur type. There are 18 mineral prediction types based on mineral prediction factors, of which sedimento-metamorphic type, sedimentary type and magmatic hydrothermal type pyrite are the most developed. Sulfur deposits are mainly distributed in rift zone, uplift zone, arc-basin system, active continental margin, etc. The metallogenic age, type and scale of the deposits formed in different tectonic environments are different. According to their regularity, they can be divided into five metallogenic stages: Including Archean, Mesoproterozoic, Late Paleozoic, Mesozoic and Cenozoic. The sulfur mineralization has undergone multiple phases of tectonic evolutionary cycles. which are divided into volcanic eruption-sedimentation events during Neoarchean-Paleoproterozoic accretion and amalgamation of continental crust, exhalaive hydrothermal-sedimentary events during Neoproterozoic-Mesoproterozoic extensional rifting of North China craton, volcanic eruption-intrusion events during uplift of North China block and deposition of epicontinental basin in Late Paleozoic, tectono magmatic events during the superposition and transformation of the Paleo-Pacific tectoinc domain in Mesozoic, salt lake deposition during extension and thinning of intracontinental basin in Cenozoic. On the basis of the evaluation of mineral resource potential, 22 important sulfur prospecting areas are divided in North China, showing good metallogenic conditions and prospects.
