Geology 1200 Study Guide 2 1 Identify the metamorphic rock being described V Calcite rich and nonfoliated V Loosely coherent and composed of broken fragments formed along a fault zone V Represents a grade of metamorphism between slate and schist V Composted of tiny chlorite and mica grains and displays excellent rock cleavage V Hard and nonfoliated often produced by contact metamorphism 2 How is conglomerate different from metaconglomerate a Conglomerate rocks can become metaconglomerate they differ in formation and physical characteristics Conglomerate is a mix of large and small grains and contains silicon Metaconglomerate is made of the same components but has undergone one or more types of metamorphism deforming and elongating the rocks 3 Label each area with the appropriate environment listed A Contact Metamorphism Subduction Metamorphism Regional Metamorphism Burial Metamorphism Hydrothermal Metamorphism monw From left to right DACBE 4 What type of fault has little or no vertical movements of the two blocks a StrikeSlip 5 What feature in distorted layered sedimentary rocks are evidence for horizontal compression and shortening a Tight Folds 6 Which of the following best describes the Great Rift Valley of East Africa a Mainly normal faulting as East Africa begins to fragment 7 What fault in California is the boundary between the North American and Pacific plates a San Andreas strike slip fault 8 Which one of the following situations results in folding of flatlying sedimentary strata a Horizontally directed compressive stress 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 What type of faults are the products of horizontally directed extensional stresses a Normal faults What types of movement are characteristic in normal and reverse faults a Dip slip Which one of the following would not be a characteristic of the San Andreas fault zone a Steep near vertical dipslip faults scarps What is a transform fault a a strikeslip fault that forms the boundary between tectonic plates What are factors for strength of a rock a Temp b Stress c Time d Confining Pressure Compressional force creates a Reverse thrust faults What is a monocline a A large steplike fold in otherwise horizontal sedimentary strata What is an example of a strikeslip fault a San Andreas Fault What is an accretionary wedge a An accumulation of sediments and ocean crust scraps Two crustal fragments welded together are called a Sutures Plate boundaries that are associated with mountain chains a Compressional plates thrust faults What type of fault has little or no vertical movements of two blocks a StrikeSlip What results from thrust faulting a Earths crust is shortened and thickened Which of the following situations would promote brittle instead of plastic deformation a Cool temperatures What is a horst a Uplifted block bounded by two normal faults What results from jointing in rocks a Roughly parallel fractures separating blocks that show no displacement What is consistent with deformation by folding a Horizontal distance is shortened perpendicular to the folding axes What is a syncline a A fold in which the strata dip towards the axis What feature in distorted layered sedimentary rocks are evidence for horizontal compressions and shortening a Tight folds What is a reverse fault a Where the hanging wall block moves up relative to the footwall block along an inclined fault 29 Regarding rock deformation a Rupture and plastic deformation occur when stresses exceed the elastic limit of a material 30 What is a thrust fault a Low angle reverse fault 31 What is a normal fault a Hanging wall blocks above an inclined fault and plane moves downward relative to the other block 32 What is a graben a Hanging wall block moved down between two normal faults
