Description
Summary:The rates of the chemical erosion for Paramushir Island, north Kuril Arc, were studied. The rates of the chemical erosion for Paramushir Island, north Kuril Arc, were studied. They were based on the results of the flow rate measurements and chemical analyses of 35 river’s water, sampled in July 2017. The silicate weathering fluxes caused by the subsurface thermal and two different types of surface waters (acid SO4 and near-neutral Na (Ca)-HCO3) of Paramushir have been estimated as 1095±200, 203 ±100 and 64 ± 20 t/km2/year, respectively. The total chemical weathering flux for Paramushir Island is estimated as 120± 40 t/km2/year.
