rocks and metamorphic rocks
Metamorphic Rocks
Sedimentary Rocks
chemical sedimentary rocks
chemical sedimentary rocks
100
an aggregate of 2 or more minerals
What is a rock?
100
1. Texture - foliated or non foliated 2. Chemical Comp.- foliation - any planner arrangement of fine mineral grains
What are metamorphic rocks based on (2 things)
100
1. Clastic 2. Chemical/Biochemical 3. Organic
What are the three groups of sedimentary rocks?
100
to turn to stone 1. compaction 2. cementation 3. precipitation of ions from a solution
What is lithification?
100
very impacted, soft black coal
What is Bituminous?
200
metamorphic- interlocking crystals igneous- melted rock magma or lava, interlocking crytals sedimentary sediment/ interlocking crystals
What are the three types of rocks and definition?
200
Schlistosity- muscovite and biotite that have been allogated Compositional- chemically segregated minerals
What are the two types of foliation and definition?
200
sediment of a particular size
What is a clastic?
200
1. Chemical to evaporation to salts (Halite Gypsum) 2. Biochemical to clam forming shell
What are the two ions that come out of a solution?
200
very impacted, hard black coal
What is Anthracite?
300
heat and pressure
What are the two agents of metamorphism
300
confined pressure all one mineral
What are characteristics of non foliated rocks
300
Gravel- greater than 2mm ex. Congomerite Sand 1/6mm -2mm ex. Sandstone Mud- less than 1/6mm ex. mudstone
What are the three common clasts and an example of each?
300
1. Halite/ Rock Salt 2. Gypsum/ Rock Gypsum 3. Calcite/ Limestone
What are the 3 common chemical minerals/ rocks?
300
1. peat 2. lignite 3.bituminous 4. anthrocite
What are the 4 stages of coal development?
400
contact- rocks in contact with magma or lava regional- mountain building hydrothermal
What are the three types of metamorphism?
400
1. Marble 2. Quartzile- quartz rich in sandstone
What are two types of non foliated rocks?
400
breaking pre existing rock material into smaller pieces. Can be physical or chemical
What is Weathering? What are the two types?
400
partially altered plant material
What is peat?
500
Heat: 1. magma source 2. Mt. Building Processes Pressure: 1. Mt. Building Processes 2. Pressure of overburden
What are the two ways of heat and pressure for each?
500
transportation of sediment through wind, water, and ice
What is erosion?
500
soft brown coal ( high sulfer content)
What is lignite?
