TLDR
Apatite dissolution and solubility in the peraluminous haplogranite system were investigated in three sets of experiments at 750°C and 200 MPa (PH2o), as functions of Ap grain size, abundance (melt: Ap ratio), and melt ASI [alumina saturation index: mol. as mentioned in this paper.About:

Aluminium saturation in I- and S-type granites and the characterization of fractionated haplogranites
TL;DR: In an unfractionated state, there are some overlaps in the degree of Al saturation in these mafic granites produced by partial melting as mentioned in this paper, but when extended fractional crystallization of these felsic partial melts took place, an almost complete separation in Al-saturation developed between I-type and more peraluminous S-type melts.

U-Pb zircon, geochemical and Sr-Nd-Hf isotopic constraints on age and origin of Jurassic I- and A-type granites from central Guangdong, SE China: A major igneous event in response to foundering of a subducted flat-slab?
TL;DR: In this paper, the ages of the Nankunshan alkaline granite and the Fogang granitic batholith are reported. But the authors do not identify the type of granites.

Apatite, Monazite, and Xenotime in Metamorphic Rocks
Frank S. Spear,Joseph M. Pyle +1 more
TL;DR: A quick survey of phosphate mineral descriptions at a commercial mineral web-site revealed over 500 phosphate mineral names and only three are common in metamorphic rocks: apatite, monazite, and xenotime as discussed by the authors.

Trace element partitioning between apatite and silicate melts
Stefan Prowatke,Stephan Klemme +1 more
TL;DR: In this paper, the apatite/melt trace element partition coefficients for a large number of trace elements (Cs, Rb, Ba, La, Ce, Pr, Sm, Gd, Lu, Y, Sr, Zr, Hf, Nb, Ta, U, Pb, and Th) were presented.
Journal ArticleDOI
Apatite in Igneous Systems
TL;DR: Pan and Fleet as discussed by the authors discuss some aspects of the occurrence, texture, composition, physical chemistry and petrogenetic significance of apatite in felsic rocks (i.e., andesite to rhyolite, and their plutonic analogs), in mafic (e.g., basalts and related rocks, and PLutonic analogues), and ultramafic rocks of the Earth's crust and mantle.

Experimental determination of the fluid-absent melting relations in the pelitic system
Daniel Vielzeuf,John R. Holloway +1 more
TL;DR: In this article, the melting of a natural metapelite under fluid-absent conditions was studied experimentally and a series of P-T, T-XH2O, and liquidus diagrams were proposed.

Phase equilibria and melt productivity in the pelitic system: implications for the origin of peraluminous granitoids and aluminous granulites
TL;DR: In this paper, the authors have studied experimentally the vapour-absent melting behavior of a natural metapelitic rock and their results differ greatly from those of previous experimental and theoretical investigations of melt productivity from metamorphic rocks.

The behavior of apatite during crustal anatexis: Equilibrium and kinetic considerations
T. Mark Harrison,E. Bruce Watson +1 more
TL;DR: In this paper, the authors examined the solubility and dissolution kinetics of apatite in felsic melts at 850°-1500°C and showed that at 6 wt% H2O, the diffusion energy of P reaches an activation energy (E) of 143.6 ± 2.8 kcal-mol−1 and frequency factor (D0) of 2.23+2.88−1.

Fluid-absent (dehydration) melting of biotite in metapelites in the early stages of crustal anatexis
TL;DR: Experimental investigation of the fluid absent melting reaction has shown that the reaction has a positive dP/dT at least up to 10 kbar, compared to a calculated backbending in a simplified system.
