|
Rhyolite #2: extrusive, felsic, viscous lava cools into obsidian, glassy, grey to white
decorative stone, jewelry, asphalt
oceanic islands and rifted continental crusts |
|
|
Granite #3: intrusive, felsic, coarse-grained mountain belts and continental shield
light-colored with pink, white, grey grains large
counter tops, floor tiles, paving stone, building veneer and cemetery monuments |
|
|
Gabbro #5: dark, greenish, white coarse-grained, intrusive, mafic
mountainous area that emerged from shifts in tectonic plate
provides a dense, hard building material with many uses
|
|
|
Basalt #8: dark-colored, fine-grained, extrusive rock, such as a lava flow
shield volcanoes, mafic - bad surface not stable
road base, concrete aggregate, asphalt pavement aggregate, railroad ballast |
|
|
Andesite #11: extrusive, color=variable, but typically bluish-grey or grey (lighter than basalt), intermediate
convergent plate margins
tiles, bricks, or stones that are suitable for water or landscape gardens - high silica = bad slope, slip resistant |
|
|
Diorite #12: coarse grained, intrusive, intermediate
volcanic arcs
building facings, foyers |
|
|
Pumice #4: release of gas, vesicular, felsic, extrusive
composite volcanoes
lightweight concrete or insulative low-density cinder blocks |
|
|
Obsidian #9: extrusive, felsic, glassy (rapid cooling)
obsidian flows
cutting tools, jewelry |
|
|
Kaolinite #31: mineral: clay, chalky
used for pottery/ china |
|
|
Sandstone #13: sedimentary, impermeable, can be good or bad slope, prone to landslides, white/reddish
glass making, building if compacted |
|
|
Shale #19: sedimentary, impermeable, black and not glassy, foliated, landslides
used for OIL |
|
|
Limestone #20: sedimentary, grey and glassy, impermeable aquitard
neutralise excess acidity, used to make glass and cement |
|
|
Conglomerate #23: sedimentary, impermeable, many rocks combined
decoration of walls and floors; if hard can be used as aggregate, fill etc. in the construction and roading industries. |
|
|
Slate #29: metamorphic, fine-grained, foliated, grey-er than shale, like hard mudstone
created by shale and convergent plate boundaries
roofing, flooring and flagging because of its durability and attractive appearance |
|
|
Schist #36: medium grained, foliated, lighter and darker bands, often shiny
decorative rock for gardens |
