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
