INFLUENCE OF MINERALOGY AND GRAIN SIZE ON THE ELECTRON SPIN RESONANCE SIGNAL OF LOESS. David N. Lumsden and Aaron Broughton, The University of Memphis, Memphis, Tennessee. Electron spin resonance (ESR) can be used to determine absolute age. The ESR signal of loess is composite from quartz, feldspar, dolomite, and clay. The latter two are easily removed. Samples of quartz, microcline, and albite in five silt-size ranges were annealed at 250[degrees]C and then dosed with 2, 4, 8, 16,...
