Rocks, Rocks, and more Rocks
Sedimentary- Sedimentary Rocks are formed by sediments cementing together or evaporating from water. Sedimentary rocks are formed in water or within the earths crust. Sedimentary rocks consist of Crystalline, Clastic, and boiclastic, Crystalline is formed by evaporation of water, Clastic and boiclastic are formed by cementing and compacting minerals together, bioclastic are formed with organic life.
Metamorphic- Metamorphic Rocks are formed by heat and pressure. Metamorphic Rocks are formed within the earth. Metamorphic rocks are either Foliated or Non-Foliated. Foliation is formed by heat and pressure and Non-Foliation is formed be contact heat.
Formed in lava and cooled fast, Fine textured small. tiny crystals, non-vesicular. Its dark gray, dense and mafic.
Inorganic rock, large sediments cemented together. Mostly quartz, feldspar and clay minerals; may contain fragments of other rocks and minerals. Rounded fragments.
Foliated rock with fine grain, composed of Mica, quartz, feldspar, amphibole, garnet, pyroxene, Regional metamorphism, Low-grade metamorphism of shale.
