2.2 Thin Sections – Introduction to Petrology

Question 2.2.2 An electron microprobe determines the composition of a mineral in thin section by comparing X-rays generated from a beam of electrons hitting the atoms within the mineral to a set of compositional standards. What is the difference between a “microprobe” thin section and a standard thin section, and why do you think this difference is necessary?

Covellite - Wikipedia

Naturally occurring. Covellite is commonly found as a secondary copper mineral in deposits. Covellite is known to form in weathering environments in surficial deposits where copper is the primary sulfide. As a primary mineral, the formation of covellite is restricted to hydrothermal conditions, thus rarely found as such in copper ore deposits or as a volcanic sublimate.

Minerals are naturally occurring, inorganic, solids with a specific chemical formula and atomic arrangement. Minerals are classified based on characteristics such as hardness and crystal shape (e.g., hexagonal, cubic). An example is Quartz – Silicon dioxide (SiO 2).

Albite - NOVA Mineralogy

Albite is the sodic end member of both the plagioclase feldspar series and the alkali feldspar series.. If you have trouble remembering the name of the white feldspar and you’re at all familiar with Harry Potter, think of Albus Dumbledore, whose first name, Albus, is Latin for white.It’s helped a surprising number of people keep their feldspars straight.

Optical mineralogy - Wikipedia

Optical mineralogy is the study of minerals and rocks by measuring their optical properties. 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.

Fracture. Cleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage.
