Which type of rock?
Organic limestone: Sedimentary, organic sediment, from the accumulation of shell and coral debris
Which type of rock?
Granite: Igneous, intrusive, felsic, light coloured, consists of feldspar, quartz and mica
Which type of rock?
Gabbro: igneous, intrusive, mafic, dark, little or no quartz
Which type of rock?
Rhyolite: igneous, extrusive, felsic, fine grained
Which type of rock?
Basalt: igneous, extrusive, mafic, fine grained, dense
Which type of rock?
Obsidian: igneous, extrusive, very rapid cooling, black (dark), glassy surface
Which type of rock?
Pumice: igneous, extrusive, felsic, holes, very light
Which type of rock?
Tuff: igneous, extrusive, materials that were ejected by a volcano fell to earth and than lithified into a rock, volcanic ash and sometimes larger particles
Which type of rock?
Conglomerate: sedimentary, clastic sediments, large round particles, space is filled with small particles, chemical cement
Which type of rock?
Breccia: sedimentary, clastic sediments, large angular fragments, space is filled with small particles/chemical cement
Which type of rock?
Sandstone: sedimentary, clastic sediments, sand-size weathering debris, rough surface
Which type of rock?
Shale: sedimentary, clastic sediments, clay-size debbris, smells earthy
Which type of rock?
Marl: sedimentary, clastic sediment, fine grained, consisting of clay and calcium carbonate, reacts with acids, smells
Which type of rock?
Limestone: sedimentary, chemical sediment, calcium carbonate, reacts with acid, formed from precipitation of CaCO3 from lake or ocean water
Which type of rock?
Rock salt: sedimentary, chemical sediment, evaporation of saline water, dissolved material become oversaturated and precipitated, smells satly, greasy feel
Which type of rock?
Gypsum: sedimentary, chemical sediment, found in layered sedimentary deposits, in association with rock salt, white to gray or salmon coloured
Which type of rock?
Chert: sedimentary, chemical sediment, microcrystalline rock of SiO2 (silicon dioxide), breaks with a conchoidal fracture, very sharp edges
Which type of rock?
Radiolarite: sedimentary, organic sediment, siliceous, fine grained, composed of microscopic remains of radiolarians
Which type of rock?
Coal: sedimentary, organic sediments, formed from plant debris, low density
Which type of rock?
Gneiss: metamorphic, high grade metamorphism, same minerals as granite, shows layers/bands
Which type of rock?
Schist: metamorphic, fine, layers, mica -> shiny, intermediate metamorphism
Which type of rock?
Slate: metamorphic, folliated, very fine, shale or mudstone
Which type of rock?
Marble: metamorphic, non-folliated, compact mass, formed from crystals, reacts with acids, limestone or dolomite
