A comparison of particle shape characteristics of crushed ...

The samples both granite and basalt rocks, taken from different deposits, were crushed in the same way. The rocks to be crushed were characterized by structure of mineral composition and some physical properties. Particles produced by crushing were characterized by three shape coefficients. These characteristics were analysed comparatively in the context of rock properties and particle diameter. From the analysis there is no evident relation between shape of particles

Roundness (geology) - Wikipedia

Rounding, roundness or angularity are terms used to describe the shape of the Gypsumers on a particle (or clast) of sediment. Such a particle may be a grain of sand, a pebble, cobble or boulder.Although roundness can be numerically quantified, for practical reasons geologists typically use a simple visual chart with up to six categories of roundness:

Granite - Wikipedia

Granite (/ ˈ ɡ r æ n. ɪ t /) is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in various kinds of igneous intrusions.
