Q

Identify this metamorphic rock

A

Phyllite has a marked fissility (a tendency to split into sheets or slabs) due to the parallel alignment of platy minerals; it may have a sheen on its surfaces due to tiny plates of micas. Its grain size is larger than that of slate but smaller than that of schist.

31
Q

Identify this igneous rock

A

Dacite, porphrytic texture, grey ground mass with ampibole crystals, felsic and formed from low temp lava

32
Q

Identify this igneous rock

A

Obsidian, volcanic glass formed from extremly quick cooling of lava

33
Q

Identify this igneous rock

A

Granodiorite, contains quarts, coarse grained and flesic, granodiorite contains more plagioclase (calcium and sodium) feldspar than potassium feldspar and has more dark minerals in it. Formed from slow cooling at low tempreture

34
Q

Identify this igneous rock

A

Pumice, comprised of tiny shards of volcanic glass, it is light weight and rough to the touch

35
Q

Identify this sedimentary rock

A

Oolithic sandstone, Well sorted, reacts with acid, a type of sedimentary rock, usually limestone, made up of ooids cemented together. An ooid is a small spherical grain that forms when a particle of sand or other nucleus is coated with concentric layers of calcite or other minerals. Ooids most often form in shallow, wave-agitated marine water.

36
Q

Identify this sedimentary rock

A

Micrite, Dense, uniform, fine grained rock with conchoidal fracture. Reacts with acid and is made of calcite.

37
Q

Identify this mineral

A

Halite,its distinctive taste, combined with its perfect cubic cleavage, low hardness, and the ease with which small fragments dissolve in water should make it easy to identify. NaCl, Halide

38
Q

Identify this igneous rock

A

Basalt, Fine grained dark mineral, mafic, formed from fast cooling of high temp lava

39
Q

Identify this sedimentary rock

A

Coal, is blocky and appears shiny and smooth when you first see it, but look closer and you might see it has thin, alternating, shiny and dull layers

40
Q

Identify this igneous rock

A

Granite, Felsic, contains quartz,feldspar, and biotite, coarse grained, formed from slow cooling at a low temp
