Phaneritic: Coarse-grained texture due to slow cooling (typical of plutonic rocks). Granite is a common example of a phaneritic igneous rock. This rock has large, visible crystals of minerals such as quartz, feldspar, and mica. Aphanitic: Fine-grained texture due to rapid cooling (typical of volcanic rocks).

Diorite: Diorite has a coarse-grained texture with visible mineral grains, and it often has a speckled appearance due to the presence of hornblende. Gabbro: Gabbro also has a coarse-grained texture but lacks the distinctive mottled appearance of diorite. It is typically dark-colored and may contain larger crystals of pyroxene. Applications:

Backfill materials that are commonly used are described below with their engineering properties. 1. Coarse-grained soils. Coarse-grained soils include gravelly and sandy soils and range from clayey sands (SC) through the well-graded gravels of gravel-sand mixtures (GW) with little or no fines. They will exhibit slight to no plasticity.
