Mineral accretion process

The exception is chemical reactions that form mineral rocks. These reactions have been explored by geochemists, and some interesting processes have been proposed to exploit them. A prominent example is the mineral accretion process, developed by W. H. Hilbertz, an architect, to build homes in the ocean [17]. Hilbertz proposes to use this process to...

Osteoid Etidronate suppresses bone turnover and may retard mineralization of osteoid laid down during the bone accretion process. In patients with fractures, especially of long bones, it may be advisable to delay or interrupt treatment until callus is evident. 

Mineralo cal diversity increased with the advent of asteroid melting and differentiation - processes that resulted in the large-scale separation of stony and metallic components. Differentiated meteorites include several classes of stony achondrites, as well as stony-iron and iron meteorites. Nevertheless, no more than -150 mineral species are known to occur in all types of meteorites. These minerals, dominated by magnesium silicates, provided raw materials for the accreting Earth. 

The nature of specific minerals found in meteorites, and their chemical compositions, as well as the cooling rates determined for irons and stony irons indicate that high hydrostatic pressures did not exist. The temperature profiles are consistent with those that asteroids (<1000 km diameter) would have had over the 4.57 Ga history of the Solar System (7). These minerals include those formed during primary nebular condensation and accretion into primitive parent bodies and those formed by secondary processes -thermal metamorphism and/or differentiation - during alteration of primitive bodies into evolved ones.
