摘要:Abstract(#br)Eight pronival (protalus) ramparts from alpine southern Norway were dated using Schmidt-hammer exposure-age dating (SHD) based on local high-precision linear calibration equations. SHD ages were − 1355 ± 1240 to 815 ± 1000 years for three active ramparts and ...

摘要:... In contrast, the morphological and spectral characteristics of Bosumtwi crater exhibit striking similarities to those of martian rampart craters, especially double-layered ejecta craters. We therefore suggest that Bosumtwi crater was originally built as a Mars-like rampart cr...

摘要:Abstract(#br)Rock glaciers and protalus ramparts are characteristic landforms of the periglacial domain often used as markers for the occurrence of permafrost in mountain terrains. As such, relict rock glaciers can be used for paleoclimate reconstructions. We present here the f...

摘要:... The study suggests that at the site “Lungijn Durvulzhin” the oldest part of the ramparts was constructed at 60 ± 100 BC (OSL), confirming human occupation and settlement activities during the Xiongnu period (200 BC–150 AD) and indicating reconstructing during 950...

摘要:Abstract(#br)Pronival (protalus) ramparts at three sites in southern Norway—Smørbotn, Alnesreset and Nystølsnovi—are assessed in relation to evidence of snow-avalanche activity, and dated using Schmidt-hammer exposure-age dating (SHD). The position of each rampart sugg...

摘要:Abstract(#br)We present a regional inventory of rock glaciers ( n = 1514) and protalus ramparts (228) for the Lombardy region, central Italian Alps. To identify and classify the landforms we inspect three sequential air-orthophoto mosaics and a 2 m-DSM, and conduct confirmat...

摘要:... The subject of this research is the rampart wall (10th century) and the buildings directly connected to the wall, i.e. the Refectory and the Abbot’s Lodge. This research deals with the causes of deformation and the subsequent consequences—the leaning of the rampart wall...

摘要:... Instead, we interpret the ridge as a pronival (protalus) rampart formed by supranival debris supply–from the ca. 200 m‐high southeastern slopes of Dundas Ridge–across a snowbed. Re‐distribution of snow by prevailing westerlies from Mt Dundas Ridge into the basin w...

摘要:... This study evaluates possible cases of landform transitions from pronival (protalus) ramparts to moraine ridges, and from pronival ramparts to lobate rock glaciers (protalus lobes) at the foot of the headwall of Smørbotn cirque in southern Norway. The five landforms had bee...
