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[5] and perraultite.[4] It is chemically related to bafertisite, cámaraite[2] and emmerichite.[5] 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.[5] 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.[6][7] References1. ^{{Cite journal|authors= Sokolova E, Camara F, Hawthorne F C, Abdu Y|title= From structure topology to chemical composition.
