The diverse mesoscopic structures in rapakivi granites of Southeastern Finland : episyenites and related processes [PDF]

, 2020
Peralkaline syenites and granites form a small yet significant group of rocks within the A-type granite association worldwide. Although the Mid-Proterozoic Finnish rapakivi (A-type) granite complexes are voluminous in southern Finland, they only host ...

Formation of Rapakivi Textures in Granite of the Deer Isle Pluton, Maine

, 2007
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.

Contrasting Sr and Nd isotopic behaviour during magma mingling; new insights from the Mannum A-type granite

, 2011
The Mannum granite in South Australia is a classic A-type granite which displays good evidence for magma mingling, such as numerous syn-plutonic mafic enclaves, and rapakivi feldspars in both the granite and enclave.

Sulphides in gabbroid rocks of the anorthosite-rapakivi granite complexes

, 2010
Наведено дані щодо хімічного складу і форм виділення сульфідних мінералів у мафітових породах коростенського та корсунь-новомиргородського комплексів. Найпоширенішими є пірит і піротин, що зазвичай містять помітну домішку міді, цинку та кобальту.
