Micromount specimen collecting has a number of advantages over collecting larger specimens. Micromount specimens take up less space and cost less than larger specimens. Small crystals are usually more perfect than larger ones. Micromount material can often be readily collected at locations that rarely if ever yield specimens with large crystals.
Creedite specimen, 11 x 7 x 3 cm, from Santa Eulalia, Chihuahua, Mexico; formerly in the Perkins D. Sams collection. Mineral collecting is the hobby of systematically collecting, identifying and displaying mineral specimens. Mineral collecting can also be a part of the profession of mineralogy and allied geologic specialties
Rich specimen from a 2009 gold discovery by a prospector in southeastern Yukon Territory. The gold, deposited along a fracture, appears rusty-orange in this photo. Prospecting is the first stage of the geological analysis (followed by exploration) of a territory. It is the search for minerals, fossils, precious
Mineral tests are simple physical and chemical methods of testing samples, which can help to identify the mineral type. [1] This approach is used widely in mineralogy , ore geology and general geological mapping.
The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis . Petrographic descriptions start with the field notes at the outcrop and include macroscopic description of hand-sized specimens.
In mineralogy, the type specimen, also known as type material, is a reference sample by which a mineral is defined. [1] Similar to the biology type methods, a mineral type specimen is a sample (or in some cases a group of samples) of a mineral to which the scientific name of that mineral is formally attached. In other words, a type specimen is ...
Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy [n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
Recognizing the habit can aid in mineral identification and description, as the crystal habit is an external representation of the internal ordered atomic arrangement. [1] Most natural crystals, however, do not display ideal habits and are commonly malformed. Hence, it is also important to describe the quality of the shape of a mineral specimen:
