Feldspars are mainly represented by microcline and albite, followed by orthoclase and sanidine
in some samples (Table 1).
2002, Heat transfer in quartz, orthoclase, and sanidine
at elevated temperature.
The XRD patterns indicate that the sanidine
is mixed with other K.
Syenite contained the minerals nepheline, sanidine
The flux monitors were the hornblende standard, MMhb-1, and the sanidine
standard, Fish Canyon tuff.
Typical minerals found in lamproite rocks include forsterite, leucite, phlogopite, and iron-rich sanidine
The hyalite-bearing layer is composed of 3-50 mm rhyolite rock fragments mixed with 1-4 mm dipyramidal fe-quartz and limpid sanidine
phenocrysts in a weakly welded, porous, siliceous, tuffaceous matrix.
Analyses were calibrated using albite (Na), sanidine
(Si, Al, and K), diopside (Ca and Mg), almandine (Fe), rutile (Ti), fluorapatite (P), and rhodonite (Mn) standards.

Oxley mineralization is an unconventional, hard-rock style of potash mineralization, hosted by a series of ultrapotassic microsyenite lavas, which typically contain more than 90% sanidine
