Geology of Titanium-mineral Deposits
Andesine versus labradorite anorthosite association. Massif anorthosites show a
spectrum from bodies of labradorite composition to bodies of andesine
composition (Anderson and Morin, 1969). Andesine in the latter commonly is
antiperthitic ...

Geological Survey Professional Paper
As is typical for other plutons in the Antarctic Peninsula, plagioclase in the west
Wegener Range batholith is normally zoned; most crystals are calcic oligoclase
to sodic andesine, but rims may be as sodic as sodic oligoclase. K-feldspar lacks

Gemstones: Properties, Identification and Use
Andesine Andesine feldspar is composed of 50-70 per cent albite and 30-50 per
cent anorthite. The first discovery of andesine feldspar with gem potential was
made in 1967 when a US laboratory identified a massive green jade-like
cabochon ...

The identification of detrital feldspars
Feldspars showing lower indices of refraction than the index of Canada balsam,
therefore, are alkali feldspars. If all the visible indices are greater than that of the
balsam, the plagioclase is frequently as calcic as an acid andesine.

Geology and ore deposits of the Montezuma Quadrangle, Colorado
Rocks of this group are characterized by abundant plagioclase, generally
ranging in composition from calcic andesine to labradorite, but in some places
bytownite occurs. Ortho- clase is rarely found, augite is common, hornblende and
biotite ...

The mineral grains, which average about 3 millimeters in diameter, are
