Formation of Sandstone and Amphibolite

Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand. Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Amphiboles

Amphiboles are elongated and generally dark-colored silicate minerals. Amphiboles are both structurally and compositionally similar to pyroxenes (other large group of silicate minerals). Both amphiboles and pyroxenes are very important rock forming minerals. However, their presence in sand is generally much smaller than one would assume.
