Chalcopyrite with minor malachite mineralization dominating the cement of a hydrothermal breccia with
K-feldspar altered megacrystic syenite clasts.
K-feldspar altered megacrystic syenite with chalcopyrite mineralization found in outcrop at "Rock Island II"; a new showing ~470 meters NE of Burgundy Ridge.
Alteration is mainly
K-feldspar and hydrothermal biotite with abundant sulphide mineralization.
For example, rocks containing nepheline are considered more effective in improving soil productivity than those containing
K-feldspar (Manning 2010).
The Bt horizon is characterized by relatively high contents of
K-feldspar and plagioclase.
Minerals include quartz,
K-feldspar, (microperthite, microcline), plagioclase, aegirine-augite, hornblende, titanite, epidote and magnetite.

K-feldspar(2013) who reported that
K-feldspar (where [K.sup.+] is a countercation to the negatively charged alumino-silicate framework), a component in Saharan Desert dust, is an exceptionally potent ice nucleator (IN), inducing crystallization in otherwise pure water at around -15[degrees]C, more than 20[degrees]C above the temperature of spontaneous crystallization of pure water.
The dominant minerals are plagioclase phenocrysts, quartz,
K-feldspar, and hornblende and accessory minerals such as biotite, pyroxene, apatite, sphene, and opaque minerals can be seen in some of these rocks.
Feldspars: This category included single crystals of
K-feldspar, microcline and plagioclase, as well as potassium feldspar and plagioclase included in intraclasts, phaneritic rock fragments, and sedimentary rock fragments (meta-arenites).
