Automated mapping of K-feldspar by electron backscatter diffraction and application to 40Ar/39Ar dating

McLaren, Sandra; Reddy, Steven M.

Description

The ability to quantify feldspar microstructure using the electron backscatter diffraction (EBSD) method has direct application in the study of rock deformation and strain kinematics. However, automated EBSD analysis of low symmetry phases, such as feldspar, has previously proven difficult. Here, we successfully apply the EBSD method to a number of granitic feldspars and develop automated phase and orientation mapping to discriminate K-feldspar and plagioclase, and quantify orientation...[Show more]
