Petrology and geochemistry of Late Triassic rapakivi-type granites in the Dupangling area, South China: Role of fluid-rock interaction in the origin of rapakivi texture

open access: yesLithos, 2023
Rapakivi-type granites not only document magmatic processes but also archive subsolidus interactions between granitic rock and fluid, and thereby provide crucial information about fluid infiltration in the Earth's crust.

Rapakivi Texture in Rhyolite

Nature, 1969
RAPAKIVI texture has rarely been reported in volcanic rocks1. A notable example of a volcanic body with rapakivi texture is a Miocene rhyolite2 that has an exposure area of about 1/16 square mile near California State Highway 178 on the east flank of Rhodes Hill 1/4 mile west of the eastern boundary of Death Valley National Monument.

Bacterial weathering of rapakivi granite

Geomicrobiology Journal, 1981
Rapakivi granite samples were incubated with Pseudomonas aeruginosa culture solutions in order to elucidate the possible role of bacteria in rapakivi (crumbling stone) disintegration. SEM micrographs showed micromorphological alterations on the incubated rapakivi surface at 21 to 23°C for 20 days.

The Jaala-Iitti rapakivi complex. An example of bimodal magmatism and hybridization in the Wiborg rapakivi batholith, southeastern Finland

Mineralogy and Petrology, 1994
The dyke-like 1.63 Ga Jaala-Iitti rapakivi complex forms a 25 km long and up to 2 km wide intrusive body at the northwestern margin of the Wiborg rapakivi batholith cutting both the granites of the batholith and the surrounding 1.9 Ga Svecofennian crust.

Chapter 12 Rapakivi Granites

2005
Publisher Summary The Paleoproterozoic Svecofennian bedrock of southern Finland formed during a multiphase convergence and collision of lithospheric plates ∼ 1900 Ma ago. The next event to strongly reshape the Finnish bedrock was the emplacement of the rapakivi granites-∼1600 Ma ago, when the Svecofennian mountain chain had already been eroded down ...

Biotite from rapakivi

Mineralogy and Petrology, 1994
This paper deals with the chemical composition of biotites from rapakivi granites. For this purpose, 61 chemical analyses of biotites from composite anorthosite-rapakivi plutons in the Fennoscandian and Ukranian shields were used. Figurative points of the biotite composition were plotted on diagrams designed for biotites byFoster (1960),Winchell (1949)

Rapakivi granite, anorthosite and charnockitic plutonism

Nature, 1978
THE close association of massive anorthosite and charnockitic granitic rocks is well documented1. Rare earth element (REE) investigations2–4 have indicated that the massive charnockite (mangerite) associated with anorthosite is not comagmatic with it but represents a distinct magma fraction.

Metallogeny of the Rapakivi granites

Mineralogy and Petrology, 1995
Two major types of ore deposits occur with Proterozoic rapakivi granite plutons: (1) greisen-, vein-, und skarn-type Sn(-W-Be-Zn-Cu-Pb) deposits associated with specialized late-stage granites, and (2) Fe oxide-Cu (-U-Au-Ag) deposits.
