ALEX STREKEISEN-Baryte-
Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore. It is often associated with the minerals anglesite and celestine. This is a thin section of radial growths of Barite (or Heavy Spar). Collected from a mineral vein in the Hope Valley, near Castleton, Derbyshire.

Baryte - Wikipedia
Baryte, barite or barytes (UK: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / [citation needed]) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of the element barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid ...

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.

Thin section petrography
Thin section petrography We offer three options, depending on the degree of information required: Quicklook petrography: involves a brief description of the major detrital minerals and diagenetic phases. This is the least detailed option but facilitates rapid scanning of a number of thin sections to assess trends and variations.

BARITE. Barite occurs as an equigranular aggregate, the grade-size varying from one band to another, 0.1-0.5 mm. This banding lies parallel to the walls of the vein, and in occasional sections the barite grains are slightly elongated in that direction.

Jan 01, 2003 Because barite and celestite form a solid solution series, they are extremely difficult to tell apart in thin section. Generally, other chemical techniques must be used to be confirm identifications. Like gypsum, barite also forms crystal rosettes. Halite is difficult to see in thin section, because it is isotropic and highly soluble.
