Sediment properties, charcoal counts, and radiocarbon dates from the Frazier Mountain paleoseismic site, California

This data release provides geochemical, sedimentological, and geochronological data from interbedded mudflow and marsh deposits from the Frazier Mountain paleoseismic site, California (34.81232°, -118.9034°). The samples were collected to support paleoenvironmental reconstruction of the site and refine several previous investigations of paleoearthquakes along the San Andreas Fault (Lindvall et al., 2002; Scharer et al., 2014; Scharer et al., 2017). Geochemical and sedimentological data include grain size, magnetic susceptibility, dry bulk density, percent total organic matter, and percent total carbonate at contiguous ~1 cm spacing and charcoal counts at least every 4 cm for the 6.2 m section. The data release also compiles new and previously published radiocarbon datasets and associated depths to facilitate inter-study comparison. Finally, the macrofossil assemblage from nine units and the pollen assemblage from six units are provided within the depth context of the sedimentological samples. This report should be used as the supplementary materials for any publication(s) that uses the sedimentologic and geochemical data or taxa identification or radiocarbon dates and depths reported herein.
