Jinshajiangite is a rare silicate mineral named after the Jinshajiang river in China.Hong, W., and Fu, P., 1982. Jinshajiangite - a new Ba-Mn-Fe-Ti-bearing silicate mineral. Geochemistry 1, 458-464 Its currently accepted formula is BaNaFe4Ti2(Si2O7)2O2(OH)2F. It gives a name of the jinshajiangite group. The mineral is associated with alkaline rocks. In jinshajiangite, there is a potassium-to-barium, calcium-to-sodium, manganese-to-iron and iron-to-titanium diadochy substitution. Jinshajiangite is the iron-analogue of surkhobite and perraultite.Mindat, Perraultite It is chemically related to bafertisite, cámaraite and emmerichite.Mindat, Emmerichite Its structure is related to that of bafertisite. Jinshajiangite is a titanosilicate with heteropolyhedral HOH layers, where the H-layer is a mixed tetrahedral-octahedral layer, and the O-layer is simply octahedral.
The mineral has only two known places of natural occurrences; a dyke near Jinshajiang River, Sichuan Province and the intrusion of Norra Kärr in Sweden.
