Abstract:
The systematical division of tectonic facies can deepen the understanding of tectonic transformation between ocean and earth crust, and it is helpful to carry out mineralization prospects prediction and resource potential assessment. According to the basic characteristics of tectonic facies in Hebei Province, the tectonic facies are divided into 3 facies series, 5 macro-facies, 19 facies and several sub-facies. The authors in this paper discussed the relationship between tectonic facies and mineralization, and concluded that development and evaluation of mineralization was under a certain tectonic background, and different mineralization was constrained by tectonic environment. Tianshan-Ximeng orogenic system is mainly related to the variscan intrusive rocks, and the main ores are fluorite, with scattered beryllium, tungsten and lead-zinc. North China Craton is an important metallogenic facy, which contains iron deposits related to the banded iron formation of BIF, gold deposits related to the granite-greenstone belt, and the sedimentary metamorphic iron, talc, magnesite and graphite related to paleo-island arc subfacies. Themetallogenesis of orogenic-rift facies series in Eastern China is related to volcanic, sedimentary and intrusive lithofacies, and is dominated by contact metasomatic iron (copper), porphyry copper-molybdenum deposits and magmatic hydrothermal gold deposits, with lead-zinc mine, manganese silver mine, coal and so on. This research could provide background material of metallogenic geological environment and evaluation stage for tectonic setting and evaluation process in the study area, and geological formation and metallotectonics characteristics of different minerals in metallogeny and mineral prediction.
