原始语种摘要: Abstract(#br)The relative importance of climatic and tectonic factors in driving rates of denudation in mountain ranges has long been debated, with both precipitation and rates of crustal uplift cited as first order controls in a variety of different mountainous settings. Few studies, however, have explicitly considered the influence of climatic and tectonic processes on denudation rates during the early stages of orogenesis. Using basin-wide denudation rates derived from in-situ cosmogenic 10 Be, and published modern precipitation rate data, the significance of rainfall and snowfall on rates of denudation is evaluated for the San Bernardino Mountains, California. Denudation rates vary between 52mmka −1 in the arid northern regions...
