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.
Use of old mineral names is also discontinued, for example when a name is no longer considered valid. Therefore, a list of recognised mineral species is never complete. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.
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.

This list includes those recognised minerals beginning with the letter A.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
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.

Medical journals are published regularly to communicate new research to clinicians, medical scientists, and other healthcare workers. This article lists academic journals that focus on the practice of medicine or any medical specialty. Journals are listed alphabetically by journal name, and also grouped by the subfield of medicine they focus on.
