Combination of cathodoluminescence analysis and quantitative determination of titanium concentration in quartz, giving crystallization process of quartz : An example of the Tono plutonic complex, the Kitakami Mountains.

Abstract

This study reveals the crystallization processes of magmatic-origin quartz crystals, based on cathodoluminescence (CL) analyses and quantitative determinations of titanium concentration in quartz. The CL patterns are classified into 6 groups. Quantitative determinations of titanium concentration in quartz are analyzed by EPMA housed at Nagoya University, giving the value ranging from 40 to 200 ppm.
