Using Laser Ablation ICP-MS to Constrain the Origin of the Rapakivi Texture of the Deer Isle Pluton, Maine [PDF]
, 2008 An Ovoid K-feldspar mantled by Na-feldspar is called rapakivi. Rapakivi may form either by (1) decompression during ascent of felsic magma through the crust to a shallow magma chamber or by (2) mixing of mafic- and felsic-magma within a magma chamber. We

Changes of Granite Rapakivi under the Biofouling Influence
, 2021 Interdisciplinary study of granite rapakivi biofouling in the natural and anthropogenic environment (St. Petersburg, Vyborg, Southern Finland) was carried out. The biodiversity of microorganisms (cyanobacteria, micromycetes, and organotrophic bacteria) and various types of biofilms are characterized.
