Introduction: Understanding the impact process of ice-silicate mixtures is of importance, because water ices exist mostly in a variety of forms of mixtures with silicate or some other components (e.g. ammonia) in the solar system. Decrease of crater volume with increasing silicate content was observed in our previous impact cratering experiments of ice-silicate mixture targets performed using a...
Major rock units of Robat Sefid ophiolitic complex are Late Cretaceous in age. The abundance of rock units in this area in ascending order are: dunit, harzburgite and pyroxenite), gabbro and diabasic dikes (mostly rudenginized). Chromite lenses are generally covered by a few centimeters to several meters of ultramafic rocks mainly of dunite. Primary disseminated and massive textures are abundan...
