Question

Matching: Match each of the descriptions of marine sediments to the correct sampling location. Note: A sample may be used more than once or not at all. You have been hired as a summer intern to work for Dr. Dave at his sand laboratory in Pasadena. He has collected samples from various parts of the world and its your job to catalog the sediments. But you mix up the samples and have to quickly place the proper label back on the right sediment sample, before Dr. Dave comes to inspect your work. Hurry, you have only minutes before he makes it into the lab.

A. Fine-grained sand deposit. Grains of sand are very-well-rounded and “frosted.” The composition of the sand is dominated by quartz and minor amounts of feldspars.

B. Medium to fine-grained sand deposit composed of angular sand grains of rock fragments, feldspars, quartz and some mafic minerals.

C. Very coarse (large grains) sand deposit mixed with gravel. Composed of rounded quartz and feldspar grains with some rock fragments.

D. Sand deposit composed of mostly dark, mafic minerals and basaltic rock fragments.

E. Sand-sized particles of carbonate shell fragments. 2.1 Beach deposit from coastal California (active margin setting).

2.2 Beach deposit from the southeastern coast of the Big Island of Hawaii.

2.3 Sand dune deposit (wind-blown sand) from the Saudi Peninsula.

2.4 Stream deposit collected high in the Sierra Nevada of California.

2.5 Beach deposit from the coast of Aruba in the Caribbean.
