Gold is a placer mineral that historically sparked mass migrations of people to sites of newly discovered deposits, often changing the course of cultural and economic development. Panning for gold mimics stream actions to separate grains of gold from other mineral and rock grains. To accomplish this separation, the panner takes advantage of the difference in the specific gravity of gold ( grams per cubic centimeter) and common rocks and minerals (generally about 3 grams per cubic centimeter).
It is easy to understand now why hydrocarbons are absent to the east of the ophiolite mountain in Oman (no subduction), why oil reserves are modest in Oman, Syria, and Turkey (inadequate seepage of water), and why traps are found in formations of different ages (Upper Paleozoic to Miocene). Almost all the traps, north and south of the Gulf, are formed by and located over deep-seated horsts and/or over fractured or faulted Early Paleozoic salt domes along the gulf (North - 1985). These openings cut across the basement rocks and overlying beds, and provide access for oil and gas migration to their traps.
From the Oiled Wildlife Care Network: There are different effects on different classes of marine mammals. Heavily furred animals, such as sea otters and fur seals, are more severely affected by oiling because these species rely on their thick haircoat to maintain warmth and buoyancy. The fur traps a thin layer of air adjacent to the animal's skin (in a similar fashion to birds), and this air layer prevents the skin of the animal from coming into contact with the cold ocean water. When exposed to oil, the alignment of the hair is altered; the air layer is destroyed; and mammals rapidly become hypothermic.
