Davies_2016_Hayes_F2_average			Davies, L. J.		4058 ± 148 14C; 10771; Age is approximate. Age based on radiocarbon age models reported in Davies and others (2016). Age reported as a range (3910-4205 cal BP) and for entry into the database, a value and error were calculated from the reported range.		-1800--	Davies and others (2016) report a Hayes F2 tephra average composition calculated from two samples (see sample description for sample numbers).	Composition is calculated average from analyses of multiple samples: UA2614 and AT-2561 (reported in Wallace and others, 2014). Reported in Davies and others (2016).
