The comminution behavior of different mineral species subjected to incessant impact is investigated using targets consisting of 2-4-mm crystals of albite, augite, forsterite, of quartz, which were impacted at least 25 times at 1.4 km/sec by 3.18-mm stainless-steel spheres. Sieve analyses were performed after every five shots. It was found that the behaviors of the …

Augite is common in igneous rocks which have a relatively low percentage of silica, and frequently occurs with olivine. No hydroxyl group (OH) is present in either augite or olivine and both can be described as 'dry' minerals. These minerals are rarely found in sediments since they alter easily when exposed to water and air (Section 2.1.5).
The mineral pyroxene is a name applied to a group of silicates that are similar in composition to the hornblende group, but not so often containing soda and potash.Cleavage pieces show angles of 93° and 87°, thus making nearly square edges, a clear distinction between them and the sharp and obtuse edges of cleavage pieces of hornblende.
