摘要：Graphite deposit is important ore in Huili County, Sichuan Province. It is located in the middle part of the Kangdian axis and the middle part of the Kangdian basement fault uplift zone. The graphite deposit is located in the strata of the Dayingshan Formation of the Lower Proterozoic Hekou Group. The deposit belongs to sedimentary metamorphic graphite deposit formed under the dual factors of regional and thermal contact metamorphism. The ore body is strictly controlled by horizons. Graphite is composed of migmatized graphite quartz schist ore and migmatized graphite schist ore. The former is of the main type and the latter to the second type. Through comparative analysis of metallogenic geological and geophysical characteristics, it is considered that the gold rain graphite deposit is influenced by strata, structure, magmatic rocks, metamorphism, migmatization and other factors.
