  1. Identifying Rocks Sire Kassama 2014

  2. Conchoidal Fracture: arrowhead or inside of seashell Rhombohedral Cleavage: Deformed cube without right angles

  3. A. SLATE: shale is its parent rock B. SCHIST C. PHYLLITE What would be the correct order of metamorphic sequence, from low grade to high grade metamorphism? slate, phyllite, schist

  4. The Fall line is a Geological boundary about 20 miles wide, running from Columbus to Augusta that represents an ancient shoreline of the Atlantic Ocean of the Mesozoic separating major rock types . State the major rock type, Sedimentary or Igneous/Metamorphic for each of the 4 major geological regions of Georgia. 1. Valley and Ridge SEDIMENTARY 2. Blue Ridge METAMORPHIC 3. Piedmont METAMORPHIC/IGNEOUS 4. Coastal Plain SEDIMENTARY

  5. Need To Know on Rocks ROCK NAME TYPE ( Igneous, Sedimentary, metamorphic) FORMATION Igneous (Extrusive, Intrusive) (volcanic, plutonic) (felsic or mafic) Sedimentary ( Clastic, chemical, biochemical, organic) Metamorphic (Regional, Contact Metamorphism) (low grade-high grade) ENVIRONMENT TEXTURE Igneous (phaneritic, aphanitic, porphyritic) Sedimentary (grain size) Metamorphic Foliated or non-foliated HARDNESS RANGE MINERALS PHYSICAL DESCRIPTION (Color) USES OTHER PROPERTIES

  6. Need To Know On Quartz MINERAL FAMILY CHEMICAL FORMULA PHYSICAL PROPERTIES OF QUARTZ MINERALS: HARDNESS COLOR STREAK LUSTER SPECIFIC GRAVITY CRYSTAL STRUCTURE/HABITS CLEAVAGE/FRACTURE OTHER PROPERTIES (Unique characteristics) ENVIRONMENT ECONOMIC IMPORTANCE (USES)

  7. Other Resources The following questions and answers are from the New York State Regents Website: http://www.regentsprep.org/Regents/core/questions/topics.cfm?Course=ESCI Geology.com
