Question

1. the rock shown below has a foliated texture and contains the minerals amphibole, quartz, and feldspar arranged in coarse - grained bands. which type of rock is shown? a) gneiss b) quartzite c) slate d) dunite

Explanation:

Gneiss is a foliated metamorphic rock. It has a banded appearance with minerals arranged in coarse - grained bands. Quartzite is a non - foliated metamorphic rock (formed from quartz sandstone, mainly composed of quartz). Slate is a fine - grained foliated metamorphic rock (usually has very fine grains and a smooth surface). Dunite is an igneous rock (ultramafic, mainly composed of olivine). The rock described has a foliated texture with minerals in coarse - grained bands, which matches the characteristics of gneiss.

Answer:

A. gneiss
