MOST COMMON MINERALS Silicates: 96% Carbonates Oxides
ROCK Made up of 2 or more minerals
IGNEOUS ROCK http://mineral.galleries.com/rocks/igneous.htm
Which type of rock would have formed first on the original crust? • Igneous
Examples: sand silt clay Examples: sandstone Shale limestone SEDIMENTARY ROCK Lithification (compaction & cementation) Sediments High Temperature High Pressure Weathering Erosion METAMORPHIC ROCK IGNEOUS ROCK Melting Examples: granite basalt pumice Examples: slate marble gniess quartzite Magma Cooling Crystallization
ROCK CYCLE http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
In your own words, describe how each type of rock could turn into each of the other types of rock.
shells deposition calcite lithification limestone High heat & pressure marble
sand deposition silicate lithification sandstone High heat & pressure quartzite
clay silt deposition silicate lithification shale High heat & pressure slate
magma Cooling & Crystallization Mineral grains aligned in thick layers (foliation); less than 50% Granite High heat & pressure gneiss
EXTRUSIVE (cools quickly) magma Cooling & Crystallization heat & pressure basalt green stone Cooling & Crystallization More heat & pressure Green schist Granite INTRUSIVE (cools slowly) High heat & pressure schist Mineral grains aligned into thin layers (foliation); 50% or more
