Routine characterization and interpretation of complex alkali feldspar

It is important to consider the effect of both An content and structural state on the T at which exsolution begins. In an An-free feldspar Ab 30 Or 70, coherent exsolution would begin at ~600 °C in a fully ordered framework and at ~440 °C if fully disordered (Sipling and Yund 1976) (see also Parsons et al. 2010, Fig. 1).

Identification of Ice Nucleation Active Sites on Feldspar Dust

Mineral dusts originating from Earth's crust are known to be important atmospheric ice nuclei.
