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
A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as photomicroscopy.At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, thereby enabling the user to take photographs at reasonably high magnification.
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
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 ...
Most commonly, rock and mineral samples are prepared as thin sections or grain mounts for study in the laboratory with a petrographic microscope. Optical mineralogy is used to identify the mineralogical composition of geological materials in order to help reveal their origin and evolution.
Local minerals room – here you can find collections with more than 5,000 mineral specimens on display. It is one of the biggest and most diverse collections of minerals in the world. It includes important ore minerals, pegmatite, volcanic rocks, and others. Fluorescent minerals room – here you can explore the surreal display of fluorescent ...
In most cases, a hand specimen of the rock is accompanied by a thin section. The strengths of the collection reflect current and historical research interests, and include Cornish and Cumbrian minerals and specimens from the Binntal of Switzerland. Examples from this collection are on display in the Mineral Gallery [8]
