Hydrothermal ore minerals, which typically form from high temperature aqueous solutions, trap tiny bubbles of liquids or gases when cooling and forming solid rock. The trapped fluid in an inclusion preserves a record of the composition, temperature and pressure of the mineralizing environment. [1] An inclusion often contains two or more phases ...
A calcium–aluminium-rich inclusion or Ca–Al-rich inclusion (CAI) is a submillimeter- to centimeter-sized light-colored calcium- and aluminium-rich inclusion found in carbonaceous chondrite meteorites. The four CAIs that have been dated using the Pb-Pb chronometer yield a weighted mean age of 4567.30 ± 0.16 Myr.
The reason for the inclusion of the salt is partially cosmetic: the increase in ionic strength prevents some of the temporary skin wrinkling (partial maceration) which would occur with plain water baths. Epsom salt baths have been claimed to also soothe and hasten recovery of muscle pain, soreness, or injury.
In mineralogy, an inclusion is any material trapped inside a mineral during its formation. In gemology , it is an object enclosed within a gemstone or reaching its surface from the interior. [ 1 ] According to James Hutton 's law of inclusions, fragments included in a host rock are older than the host rock itself.
Examples showing the imposition of the host diamond's morphology on the included mineral in syngenetic inclusions. (a) Inclusion of olivine in diamond with their faces imposed by octahedral (o) and cubic (c) shapes common in diamond. (b) Diamond with several olivine inclusions with faces parallel to the octahedral diamond face.
PubMed Central (PMC) is a free digital repository that archives open access full-text scholarly articles that have been published in biomedical and life sciences journals. As one of the major research databases developed by the National Center for Biotechnology Information (NCBI), PubMed Central is more than a document repository.
The Journal of Trace Elements in Medicine and Biology is a bimonthly peer-reviewed medical journal covering the roles played by trace elements in medical and biological systems. It was established in 1987 as the Journal of Trace Elements and Electrolytes in Health and Disease , obtaining its current title in 1995.
Finally, although mineral and elements are in many ways synonymous, minerals are only bioavailable to the extent that they can be absorbed. To be absorbed, minerals either must be soluble or readily extractable by the consuming organism. For example, molybdenum is an essential mineral, but metallic molybdenum has no nutritional benefit.
