WEMINDJI GEOTOURISTIC MAP GEOLOGICAL HISTORY The Wemindji land, is part of the Canadian Shield and lies within the Archean Superior geological Province. The Superior Province comprises four geological subprovinces, from North to South: La Grande, Opinaca, Némiscau and Opa- ABOUT WEMINDJI... tica. These subprovinces are mainly composed by volcano-plutonic or metase- dimentary groups. Wemindji mean «red ochre mountain» in Cree. Wemindji Community The Wemindji land comprised the La Grande and the Opinaca subprovince. Wemindji is formerly known as Old Factory, an Island of Paakumshumwashtikw, 25 kilometres south of the current location. The name change from The La Grande subprovince is composed by volcano-plutonic rocks and the Opinaca subprovince, younger than the previous, is mainly composed by sedi- Nouveau-Comptoir followed by Paint Hills (http://www.toponymie.gouv.qc.ca). Wemindji has been relocated since 1958 and sits at the mouth of the mentary rocks thus as paragneiss. Maquatua River on the east coast of James Bay, in northern Quebec, Canada. Wemindji is located approximately 1,400 kilometres north of Mon- Montréal tréal. The Archean La Grande sequence is mainly composed by tonalite and volca- no-sedimentary rocks. Several ultramafic to felsic intrusions and some Protero- zoic gabbroic dikes and quartz-arenite basin are also present. Around 1686, the Compagnie du Nord and French Knight Pierre de Troyes deployed soldiers in the area and managed to dislodge the English from the HBC and take control of the bay for a short time. In 1935, the HBC opened a new trading post. In 1959, the village was moved toward the coast In the area, mineralization can be classified roughly into eleven types.
