Geochemistry of Major, Trace, and Rare Earth Elements in Biglar Permo-Triassic Bauxite Deposit, Northwest of Abgarm, Ghazvin Province, Iran
Biglar Permo-Triassic bauxite deposit is located in ~15 km northwest of Abgarm, southwest of Ghazvin province, west of central Iran. It consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of Ruteh (Permian) and Elika (Triassic) carbonate formations. Petrographically, the bauxite ores exhibit collomorphic-fluidal, pseudo-breccia, pseudo-porphyritic, panidio-morphic-...
متن کاملMineralogy and REE geochemistry of argillic alteration zone of the Asbkhan area in northwest of Heris, NW Iran
Intrusion of granodioritic and quartz-dioritic igneous bodies of the Oligocene age into andesitic rocks with the Eocene age resulted in occurrence of widespread argillic alteration zone in the Asbkhan area of Heris (East Azerbaijan Province, NW Iran). A significant portion of this system formed the argillic alteration zone. Based on mineralogical examinations, kaolinite, quartz, smectite, aluni...
متن کاملMineralogy and trace elements geochemistry of the RoudMajan kaolin deposit, northwest of Torbat-e Heydarieh, NE Iran
The RoudMajan kaolin deposit is located about 35 km northwest of Torbat-e- Heydarieh city, Khorasan Razavi Province, in the Great Kavir Block subzone. Field evidence and laboratories results indicate that this deposit is genetically associated with the alteration of basaltic andesite rocks (Lower Eocene). According to the microscopic evidence and various analytical techniques (XRD, SEM-EDS, FE-...
