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 ...
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
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.
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.
The drip tank allows the user to choose a drip rate via spigot and to position the spigot over the lap, nearer or farther from the arbor. 2) The dust produced from grinding minerals can cause pulmonary disease if inhaled. The flow of water captures the particles in a slurry, which drains into a rubber container around and below the lap.
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.
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.
Opened in 1997, the museum's collections date to the 1930s with the museum housed in a home built to display the rock and mineral collections of the museum founders. The ranch-style home is listed on the National Register of Historic Places, the first of its kind listed in Oregon. In 2015 the museum became a Smithsonian Affiliate museum.
