The presence of Mg, Fe, and Ca in surficial waters provokes carbonate mineral precipation, which is linked to atmospheric CO. content and climate thr

Because transport properties of rocks, including permeability and electrical resistivity, are directly determined by the pore structure (Walsh, 1965; Simmons and Richter, 1976; Gangi, 1979;

Minerals precipitated after deposition are referred to as authigenic, and they fill the primary pore space or replace detrital grains. The fluid phases may consist of liquid phases lik

Familiar examples include the relatively slow growth of faceted mineral crystals, the much more rapid growth of dendritic snow crystals, and the formation of irregular and even spongy mineral grains during weathering near the earth’s surface.

Crystal Growth and Morphology: A Multi-Faceted Approach,he driving forces for growth are rather low — do indeed grow with flat faces. This phenomenon holds for crystals with very simple structures such as the cubic and hexagonal close-packed crystals of the elements helium, argon and krypton, growing at extremely low temperatures from their melts, and cr
