Distinguishing the sources of Asian dust based on electron spin resonance signal intensity and crystallinity of quartz

We report a newly developed provenance-tracing method by using a combination of electron spin resonance (ESR) signal intensity of the E 1′ center in quartz and crystallinity index (CI) of quartz, which reflect the formation age and crystallization conditions of quartz in their source rocks, respecti...

Description
Summary:We report a newly developed provenance-tracing method by using a combination of electron spin resonance (ESR) signal intensity of the E 1′ center in quartz and crystallinity index (CI) of quartz, which reflect the formation age and crystallization conditions of quartz in their source rocks, respectively. ESR signal intensity and CI were determined for quartz in fine silt plus clay fraction (
