Mineralogical and geochemical constraints on high-sulfidation epithermal alteration in the Zamharir kaolin deposit, northwestern Iran

The Zamharir kaolin deposit in northwestern Iran represents hydrothermal alteration of the Oligocene andesitic rocks within a high-sulfidation epithermal system. Mineralogical assemblages display conspicuous spatial zonation, with kaolinite, alunite, pyrite, and rutile concentrat...
