Question

e The weathering of a granitic rock will result in stable, mechanically weathered grains that are composed of what minerals? I. Name 4 transportation media 2. 12. Hjulstrom's Diagram relates particle size to current velocity. What would be the range of velocity in a stream when sediments of FINE SAND SIZE (2mm) are being: Eroded 13. Sedimentary Structures are formed by h Currents, . Tides, A, B. & C B only 14, Any clastic rock containing 30% feldspars is: a Well sorted Litharenite, e Arkosic a Pitted e None of the above s Well rounded grains are Chemically weathered b Poorly sorted, Likely to have been transported a long distance a Always composed of olivine. 16. True or False: All beds that are >1-thick are referred to as THICK bedded 7True or False: Pyroxene and Amphibole have low chemical stability at STP and are easily destroyed by Chemical Weathering. The geologist, when looking at any new reservoir Will look at depositional environments b Diagenetic overprint. e Should always the Boss. a Only looks at data collected during the past 5 ycars e A& B
