Geological Survey Professional Paper
If one were given a number of feldspar crystals as unknowns (when in reality they
were all samples of oligo- clase, andesine, labradorite and bytownite), one could
determine analytically that they were composed principally of four oxides: Si02, ...

Metasomatic Metamorphism in Western Clearwater County, Idaho
Layers and lenticles rich in bytownite were found along the contacts of the
northernmost and the middle anorthosite bodies. In the upper parts of these two
bodies, schist inclusions are common and some inclusions consisting of
amphibolite, ...

Gems: Their Sources, Descriptions and Identification
Notable localities include Canada (Ottawa); USA (small to medium-sized pieces
of light brown bytownite from Arizona and New Mexico can be faceted into 0.5–2
ct, eye-clean stones; RI 1.57; SG 2.73) (Oregon); Mexico (large stones (yellow) ...
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Bytownite is a calcium rich member of the plagioclase solid solution series of feldspar minerals.

United States Geological Survey professional paper
The basalt and basaltic andesite generally contain one-third phenocrysts, as
much as 2 mm in diameter, of bytownite or labradorite feldspar, diopsidic to
augitic pyroxene, olivine, and magnetite in a fine-grained to dense intergranular

U.S. Geological Survey Bulletin
The possibility of an igneous origin of the bytownite anorthosite was discussed
earlier (Hietanen, 1963a, p. 69). The long thin bodies of garnet amphibolite and
hornblende-plagioclase gneiss in the southern part of the northernmost large ...

Plagioclase is granoblastic, nonzoned bytownite (Anw) with patchy alteration to
labradorite (An65). Andesine (An 35) rims and replaces composite bytownite-
labradorite grains. Minor sericite alteration has occurred. Biotite is minor as a ...
