Optical dating of earthquake related sediments were investigated including one modern.sample and three samples from a trench excavated across the 1985 Ms7.4 Wuqia Earthquake.surface rupture. The results indicated that equivalent dose (De) values vary with grain size and the.method used for De determination. The residual dose of the modern sample is 0.1 ka.(0.2–+0.2 0.1 Gy) for the quartz single grain measurements. Only 1.5–3.6% of the grains have a detectable.OSL signal. Single grain quartz ages are similar to the expected ages. Fine grain quartz results overestimate the De values and are much older than single grain quartz and coarse grain quartz small aliquot standardized growth curve (SA-SGC) ages. Single grain quartz OSL dating may be optimal for.dating earthquake related deposits, but SA-SGC can save measurement time and has potential for dating some poorly bleaching samples.
