Topic 11: Sed. Rocks

pgs (223-226)

QuestionAnswer
Contrast a mono versus poly-mineralic rock. Mono = one mineral; poly = made up of more than one mineral.
Describe most sedimentary rocks. Clastic: Rocks that form from an accumulation of sediments derived from preexisting rocks, or organic matter.
Where do sedimentary rocks form? At or near the surface under cool conditions.
How do most clastic sedimentary rocks form? Burial, compaction, and cementation.
Why do sedimentary rocks possess most of the fossils? They form under cool conditions at or near Earth's surface.
Explain crystalline sedimentary rocks such as rock salt. Sedimentary Rocks formed from inter connecting mineral crystals formed by precipitation or evaporation of an ancient, shallow, warm water lake.
Describe the orientation of most undisturbed clastic sedimentary rocks. These beds are found at the bottom of lakes or large bodies of water in a horizontal manner, one on top of another.
State how clastic sedimentary rocks are differentiated. Classification is based upon grain size. (See ESRT pg. 7)
Compare a clastic with a bioclastic rock. Clastic are inorganic. Bioclastic such as coal are organic in origin.
Define fossil: Any evidence of former life on Earth.
Please turn to page 225 and study figure 11-7. Can you differentiate between conglomerate, coquina, and rock salt?
How might one identify bioclastic fossil limestone? Apply dilute hydrochloric acid and the calcium carbonate will bubble and fizz.
