Document Summary

Carbonate rocks-why study: 10 % of exposed sedimentary sequence (30% to total column, > 2. 7 b. y. old, 20% of all oil and gas in carbonates, good aquifers, ores found in carbonates. Another way to look at the equations equilibrium. If mix equal amounts of a and b in one container and y and z in another, when the reaction reaches equilibrium the same of all four is found in each container. If can not add any more-then solution is saturated.

Less co2 in warm water, get precip (equation to left) upwelling. Carbonate compensation depth-ball experiment in ocean: shallow water favors precipitation because of photosynthesis and higher temperature, evaporation removes h2o, get precip (equation to left, decay-adds co2, get dissolution (equation to right) (cid:862)ca(cid:396)(cid:271)o(cid:374)ate fa(cid:272)to(cid:396)(cid:455)(cid:863)
