feldspar environmental impact

Feldspar

Feldspar. Feldspars are anhydrous three-dimensional aluminosilicates of linked SiO4 and AlO4 tetrahedra that contain cavities that can hold Ca2+, Na+, K+, or Ba2+ to maintain electroneutrality (Huang, 1989). From: Environmental Soil Chemistry (Second Edition), 2003. Download as PDF.

Impact of environmental noise on oscillatory pattern ...

Recently, a model for oscillatory zoning in a geochemical system (plagioclase feldspar) was proposed. In that model, oscillations in the composition are generated through a Hopf bifurcation. In this paper, the effects of fluctuations of the bulk composition are studied by means of computer simulations. It is shown that environmental noise can lead to pattern formation such as oscillatory ...
