متن کاملRoutine characterization and interpretation of complex alkali feldspar intergrowths†k
Almost all alkali feldspar crystals contain a rich inventory of exsolution, twin, and domain microtextures that form subsequent to crystal growth and provide a record of the thermal history of the crystal and often of its involvement in replacement reactions, sometimes multiple. Microtextures strongly influence the subsequent behavior of feldspars at low temperatures during diagenesis and weath...
متن کاملFirst-principles investigation of the lattice vibrations in the alkali feldspar solid solution
The heat capacities of Al, Si ordered alkali feldspars of different Na, K compositions were calculated using the density functional theory. The effect of the Na, K distribution, if random, ordered or clustered, on the resulting heat capacity was investigated on different cells with Ab50Or50 composition. For all compositions and distributions studied, the excess heat capacity of mixing is positi...
متن کاملLattice strain across Na–K interdiffusion fronts in alkali feldspar: an electron back-scatter diffraction study
Cation exchange experiments between gem quality sanidine [Formula: see text] and KCl melt produced chemical alteration of alkali feldspar starting at the grain surface and propagating inwards by highly anisotropic Na-K interdiffusion on the alkali sublattice. Diffusion fronts developing in b-direction are very sharp, while diffusion fronts within the a-c-plane are comparatively broad. Due to th...
متن کاملMicrostructures in Two Alkali Feldspar Megacrysts from the Papuk Mt., Croatia
The Papuk Mt. belongs to the Slavonian Mountains in Croatia. It is situated in the southernmost part of the Tisza Megaunit (Fig. 1). Comprehensive reviews of the geological setting of this area are given by JAMIČIĆ & BRKIĆ (1987), JAMIČIĆ (1989) and KOROLIJA & JAMIČIĆ (1989). VRAGOVIĆ (1965) gave a detailed petrographic description of the gneisses, granitoids and the pegmatites of this region. ...
