What TWO igneous rocks are: vesicular, extrusive, with a composition of potassium feldspar, quartz, plagioclase feldspar, biotite, amphibole.
Vesicular Rhyolite and Pumice
Identify the sedimentary rock: Bioclastic with a composition of calcite.
Limestone
Identify the metamorphic rock: foliated, mineral alignment, fine grain size, composed of mica
Slate
Describe how Schist could become Sandstone.
Weathering and Erosion -> sediments -> Deposition and burial -> compaction and cementation -> sedimentary rock
Melting -> Magma -> Solidifiction -> Igneous rock -> Weathering and erosion -> sediments -> Deposition and burial -> compaction and cementation -> sedimentary rock
