Shape of Particles Angular Sub-roundedWell-rounded
Angular clasts Rounded clasts Clastic rocks: Sedimentary Rocks
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 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 Chemical sedimentary rock
Sandstone # 13 Sandstone rocks are sedimentary rocks made from small grains of the minerals quartz and feldspar. 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. Clastic sedimentary rock
Limestone # 15 Limestone form organically from shells and corals. 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 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. Parent rock is the sedimentary rock shale.
Schist # 23 Schist is formed by regional metamorphism. Slightly Foliated rock.
Gneiss # 25 Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. 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.
Anthracite # 26 Metamorphic Rock Highest Quality of Coal Known as "Hard Coal“ s+Portfolio Non-Foliated rock.
Chapter 4 - Rocks What can be learned by studying rocks… We can learn mo better about earth. So what is a rock??? Its a mixture of 1 or more minerals.
