Geology Test Review Questions Flashcards | Quizlet

Faults may be recognized in the field three ways. (1) First as an abrupt change in elevation when the surrounding area is not similarly uplifted. (2) Second when there are dipping sediments that show an offset on either side of a line or trace of a presumed fault. (3) Third when there is a repeat of the sedimentary layers vertically.

Limestone Sampling and Testing Cement and Lime Mines

In faulting, the area displaced can contain similar contamination. If the deposit is broken up in blocks, additional testing will need to be done to determine the boundaries of the good limestone. Sampling and testing in the mine will need to increase. Chip samples along with face samples will be used to locate the areas of good quality stone.

Limestone Gemstones and Minerals | Gem5

Dolomite: Dolomite is similar to calcite and sits along side it in limestone. It usually occurs as a secondary mineral, formed by the reaction of magnesium-bearing fluids seeping through the limestone. It may be colorless, or white to cream and even yellow brown, sometimes pale pink. It has a vitreous luster and is translucent.

In What Rock Formations Can Gold Be Found? | Sciencing

 · Alluvium is a deposit of eroded materials and sediment that is gathered into one area. As gold and other materials are eroded, the small pieces are pushed by water and other forces into creek and river beds and other depressions. Because gold is heavier than most other naturally occurring materials, it settles at the bottom of these deposits.

WEC189/UW208: Florida''s Geological History

Many carbonate rocks, such as limestone, are derived from skeletal material from marine organisms like corals, plankton, algae, gastropods, and sea urchins. Carbonate deposits are special geologic features because they typically only form in environments with warm, shallow, clear water of marine salinity.

They form because the limestone deposits located under the ground are chemically dissolved by moving ground water. The ground water contains minerals that make the water slightly acidic. When an acid comes into contact with a rock that is composed of calcium carbonate a chemical reaction takes place. The acid "eats" the limestone.
