About Cida (Hongge) V-Ti-Fe Deposit
The Cida (红格) V-Ti-magnetite deposit in southern Sichuan is part of the Panxi (Panzhihua-Xichang) Fe-V-Ti metallogenic belt — together with Panzhihua and Baima, one of the world’s largest V-Ti-Fe resource concentrations.
Geology
The deposit is a magmatic Fe-Ti oxide segregation in the Permian Emeishan large igneous province (mafic-ultramafic layered intrusions). V-Ti-magnetite layers and disseminations form the bulk ore.
Notable Minerals
Vanadiferous magnetite, ilmenite (often coarse hexagonal plates), chromite, titanite, fluorapatite. Some pegmatitic late-stage zones produce well-formed crystals of these species.
Collector Notes
Cida is more an ore-deposit-of-record than a collector mecca, but coarse magnetite-ilmenite intergrowths from the deeper pits make instructive teaching specimens. Often grouped with Panzhihua in Chinese Fe-V-Ti collector references.
Minerals Produced Here
