Gemstone in Iran - Pasargad Neshan Pars

Some of these minerals are called magmatic minerals. Such as feldspars, zircon, kurdite, tourmaline, topaz, etc., which occur during the metamorphism. 2. The other group is formed in the contact metamorphism of silicate and argillic stones (argillaceous schists and clay), and are produced the minerals of andalusite, silimanite, and the like.

Bazman - Wikipedia

Bazman (Persian: بزمان, also known as Kuh-e Bazman) is a dormant stratovolcano in a remote desert region of Sistan and Baluchestan Province in south-eastern Iran.A 500-m-wide crater caps the summit of the dominantly andesitic-dacitic volcano, the flanks of which are covered by monogenetic centres especially to the northwest. Bazman is a geologically young volcano which formed mainly in ...
