These heavy minerals are commonly resistant ...Figure 4.1.1 4.1. 1: Granite is a classic coarse-grained (phaneritic) intrusive igneous rock. The different colors are unique minerals. The black colors are likely two or three different minerals. If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. There are three basic components of sandstones: (1) detrital grains, mainly transported, sand-size minerals such as quartz and feldspar, (2) a detrital matrix of clay or mud, which is absent in “clean” sandstones, and (3) a cement that is chemically precipitated in crystalline form from solution and that serves to fill up original pore spaces. Sillimanite is a metamorphic mineral. It occurs mostly in schist and gneiss. It may be present in lesser amount in some granites as an accessory mineral. As a sand grain it usually is accompanied by other metamorphic minerals like kyanite, staurolite, mica, and garnet. It is usually colorless or light brown in color.

Phyllite is a foliated metamorphic rock that has been subjected to low levels of heat, pressure and chemical activity. It is composed mainly of flake-shaped mica minerals in parallel alignment. The strong parallel alignment of the mica grains allows the rock to be easily split into sheets or slabs. The alignment of the mica grains gives ... Tendency to chemical cement. Ash: unconsolidated fragments under. 4 mm. Tuff: consolidated ash. Volcanic Breccia: angular fragments over 4 mm. Agglomerate: large proportion (>25%) of bombs.
