Mineralogy and the lanthanide elements geochemistry of the Baharieh kaolin deposit, east Kashmar, NE Iran
The Baharieh kaolin deposit (east Kashmar, Khorasan Razavi Province) is the product of alteration of dacitic rocks (Eocene) and is located in the Khaf-Kashmar-Bardaskan metallogenic belt. Field observations show that the development of this deposit was controlled by the tectonic system of the area and the presence of silica cap is the most important geological feature of this deposit. Mineralog...
