IV.—On Soda-Microcline from Kilimandscharo [PDF]
Geological Magazine, 1889 The material, in which this felspar occurs, was collected by Dr Hans Meyer during his visit in 1887 to the East-African “snowmountain,” the Kilimandscharo, and kindly entrusted to me for description by Prof. F. Zirkel of Leipzig, to whom I desire to express my indebtedness for assistance and advice supplied me whilst working in his laboratory.The rocks

K-metasomatism of plagioclase to produce microcline megacrysts in the Cathedral Peak granodiorite, Sierra Nevada, California, USA [PDF]
, 2001 Higgins (1999) proposed that microcline megacrysts in the Cathedral Peak granodiorite resulted from Ostwald ripening in which textural coarsening of earlier formed small K-feldspar crystals were sacrificed to feed the growth of a select few larger ...

Rietveld structure refinement of microcline
European Journal of Mineralogy, 2015 Compared with single-crystal X-ray diffraction, extracting structural data from X-ray powder diffraction (XRPD) seems meaningless for minerals with an available single crystal, such as alkali feldspar. However, alkali feldspar is highly abundant on Earth, and the feldspar structure is important in geology.
