AbstractOn the basis of the studies of field geology, strontium, hydrogen and oxygen isotopes and REE geochemistry, coupled with the dating of mineralization, the authors suggest a minerogenetic model of circulation and drawing of Late Cretaceous geothermal waters for the fluorite deposits in southeastern China. This model includes two types of mechanism: 1) the leaching‐out and drawing through deep circulation of the geothermal water, and 2) the leaching‐out and drawing through shallow circulation of the water. The fluorite mineralization of Mesozoic volcanic rock terrain is related mainly to the former mechanism, with the mineralizing material coming chiefly from the Precambrian metamorphic rocks of the basement underlying the host rocks; while that of Yanshanian granite terrain is associated with the latter mechanism, with the mineralizing material derived primarily from the host granites and sedimentary ro
