The Shahewan rapakivi-textured granite-quartz monzonite pluton, Qinling orogen, central China: Mineral composition and petrogenetic significance [PDF]
Bulletin of the Geological Society of Finland, 2002 The Mesozoic Shahewan pluton consists of four texturally different types of biotite-hornblende quartz monzonite. In the porphyritic types alkali feldspar occurs as euhedral or ovoidal megacrysts that are often mantled by one or more plagioclase shells ...

Hybridization in the subvolcanic Jaala-Iitti complex and its petrogenetic relation to rapakivi granites and associated mafic rocks of southeastern Finland [PDF]
Bulletin of the Geological Society of Finland, 1995 The 1630 Ma Jaala-Iitti complex is an example of bimodal rapakivi granite magmatism in which the interaction of granite and diabase magmas have led locally to hybridization.

The Behavior of Water in Orthoclase Crystal and Its Implications for Feldspar Alteration
Crystals, 2022 The phenomenon of feldspar alteration that occurs in the interior of feldspar crystals remains poorly understood. We observed experimentally that water can go into orthoclase crystals under pressures of up to 600 MPa at room temperature.
