Abstract :

The widespread outcrops of listweanite (carbonatized serpentinites) can be seen in south of Fariman which located near the Jarge village along the major faults inclusive Darone fault and between ophiolitic mélange complex. On the basis of petrography study , listweanites, are cryptocrystalline silicic and are type of silisic-carbonatic listweanite and on the basis of mineralogy, formed of cryptocrystalline quartz ( opal, jasper), crystalline quartz, calcite, magnesite, siderite, serpentine and opac mineral such as choromite and magnetite and relict of pyroxene.These listweanites are ortholistweanite, means effective of metasomatic alterasion of mafic and ultramafic igneous rocks and this rocks located like to cliffs, that between mafic and ultramafic rocks. Suitable factors of formation listwanite is tectonic and host rock.
