A K-feldspar–liquid hygrometer specific to alkaline differentiated magmas [PDF]
Chemical Geology, 2015 We present a K-feldspar–liquid hygrometer specific to alkaline differentiated magmas that is calibrated through the regression analysis of sanidine and anorthoclase crystals coexisting with trachyte and phonolite melts. Partial-regression leverage plots were used to determine the minimum number of regression parameters that closely describe the ...

Nanoscopic feldspar islands on K-feldspar microcline (001) [PDF]
Physical Chemistry Chemical PhysicsHigh-resolution atomic force microscopy on microcline (001) reveals nanoscopic islands, which have the same atomic structure as the terrace and are stable in contact with water. The islands were identified as an intrinsic feature of the surface.

K-feldspar sand-grain provenance in the Triassic, west of Shetland : distinguishing first-cycle and recycled sediment sources? [PDF]
, 2009 Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales and pathways. However, these insights can be obscured by difficulties in geochemically distinguishing or adequately characterising ...
