Non-clastic Sedimentary Rocks Fine particles Layered
Conglomerates have rounded clasts Breccias have angular clasts Clast refers to the fragments of rocks. Angular clasts did not erode far from where the rock formed.
Arkose # 11 http://geology.about.com/od/rocks/ig/sedrockindex/rocpicarkose.htm Arkose is a raw, coarse-grained sandstone, sandstone Clastic sedimentary rock
Gypsum # 12 Rock gypsum is an evaporite rock that forms as shallow sea basins or salt lakes http://geology.about.com/od/rocks/ig/sedrockindex/rocpicarkose.htm Chemical sedimentary rock
Sandstone # 13 Sandstone rocks are sedimentary rocks made from small grains of the minerals quartz and feldspar. http://www.fi.edu/fellows/fellow1/oct98/expert/sandstone.htm Clastic sedimentary rock
Shale # 14 Shale forms from the compaction of silt and clay that we commonly call "mud". Shale is best for fossil collection. http://geology.com/rocks/shale.shtml Clastic sedimentary rock
Limestone # 15 Limestone form organically from shells and corals. http://geology.com/rocks/sedimentary-rocks.shtml Biologic sedimentary rock
Conglomerate # 16 A conglomerate is a rock consisting of individual clasts within a finer-grained matrix that have become cemented together.clastsmatrix http://en.wikipedia.org/wiki/Conglomerate_(geology) Clastic sedimentary rock
Clastic sedimentary rock Foliated metamorphic rock Layered due to compaction Foliation Due to heat and pressure 10. What is the difference between layer and foliate or band?
Slate # 24 Slate is the lowest grade of metamorphic rock. http://geology.about.com/od/rocks/ig/metrockindex/rocpicslate.htm Parent rock is the sedimentary rock shale.
Schist # 23 Schist is formed by regional metamorphism. http://geology.about.com/od/rocks/ig/metrockindex/rocpicschist.htm Slightly Foliated rock.
Gneiss # 25 Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. http://geology.about.com/od/rocks/ig/metrockindex/rocpi cgneiss.htm Forms deep beneath the ground or regional metamorphism. Foliated rock.
Amphibolite # 21 is a non-foliated metamorphic rock that forms through recrystallization under conditions of high viscosity and directed pressure. Contact metamorphism
Marble #22 Marble is a non-foliated metamorphic rock that is produced from the metamorphism of limestone. It is composed primarily of calcium carbonate. http://geology.about.com/od/rocks/ig/metrockindex/rocpicmarble.htm
Anthracite # 26 Metamorphic Rock Highest Quality of Coal Known as "Hard Coal“ http://earthchanges.swsd.wikispaces.net/MatthewED21%27 s+Portfolio Non-Foliated rock.
