GSA Bulletin (2015) 127 (3-4): 560–583.
... on the coast of this region. Thirty-five strath terraces at different sites were dated using in situ–produced cosmogenic 10 Be concentrations from surfaces and depth profiles. These new measurements reveal abandonment ages between ca. 15 and 380 ka. The age distribution allows determining the chronology...

... from these terraces that is used to elucidate the geomorphic, fluvial, active tectonic, and climatic processes that operate at Holocene spatial and temporal scales. Detailed field mapping reveals three prominent Holocene straths and their overlying terrace deposits. Terrace ages fall into three broad...

...Noah J. Finnegan; William E. Dietrich Abstract In order to explore mechanisms of bedrock terrace formation, we have developed a numerical model that couples vertical river incision and meandering. Model results illustrate that flights of unpaired strath terraces can form purely from the internal...

...Baotian Pan; Douglas Burbank; Yixiang Wang; Guangjian Wu; Jijun Li; Qingyu Guan Abstract The timing of the development of strath terraces with respect to climatic variability remains equivocal. Previous studies attribute strath-terrace formation to glacial or interglacial climates or to variations...
