520 | _aMarginal moraines on the northern side of Grovabreen, a plateau glacier in inner Sunnfjord, Western Norway, have been mapped and morphostratigraphically correlated with the Erdalen Event and possibly the Finse Event and the ‘Little Ice Age’. Schmidt-hammer exposure-age dating was used to evaluate the age of the most distinct marginal moraines by measuring the degree of surface weathering on boulders. The lithostratigraphy of lake sediments was analysed in a core from Dalevatnet in order to correlate this stratigraphy with the marginal moraines in the catchment area of the lake and reconstruct the early-Holocene history of Grovabreen. The lake catchment was deglaciated at 10,750 cal. yr BP. Two readvances of an outlet glacier in Fagredalen were dated to between 10,340 and 9960 cal. yr BP, correlated with the two-peaked Erdalen Event. A readvance shortly after 8450 cal. yr BP can most probably be correlated with the 8200 cal. yr BP Finse Event. | ||
