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.

Copper Mineral | Uses and Properties

Actinolite-Tremolite Series. Note: Tremolite is defined as having an Mg/(Mg+Fe 2+) ratio ≥ 0.9; actinolite has a ratio of 0.5–0.9 and ferro-actinolite has a ratio of less than 0.5. The name actinolite was retained for petrological reasons in the nomenclature (Leake et al., 1997; Hawthorne et al. 2012), since it is entrenched in the literature.

Plagioclase, Hornblende, Quartz and Biotite in a Gneiss from near Flin Flon, Manitoba The clear minerals (PP) in this thin section are plagioclase (twinned) and quartz (not twinned). The green mineral (PP) is hornblende and the brown mineral is biotite (PP). The biotite is pleochroic, and some grains have a color similar to that of the hornblende.

Chromite is dark-brown to opaque at full thin section thickness. Chromite is a spinel-type mineral, like magnetite, and has an extensive solid solution in the magnetite composition direction. Cr-Mg-Al-rich chromites are realtively transparent, and can be dark-brown at full thin section thickness.

Sphalerite - NOVA Mineralogy

Bornite is a copper iron sulfide mineral with a chemical composition of Cu 5 FeS 4. It occurs in igneous, metamorphic, and sedimentary rocks. Minable concentrations of bornite occur in hydrothermal veins, contact metamorphic zones, and in the enriched zone of many sulfide mineral deposits.

ORE MINERALS UNDER THE MICROSCOPE

minerals when seen on the polished section results from the deO'ree of polish which is needed in the study of opaque'" minerals. Because most of the ore minerals are essentially opaque in any thickness that can be con­ veniently handled, it is impossible to study them in the familiar thin section used for;,th,e study of rock speci­ mens.
