Age and development of active cryoplanation terraces in the alpine permafrost zone at Svartkampan, Jotunheimen, southern Norway (2019)
Journal Article
Matthews, J. A., Wilson, P., Winkler, S., Mourne, R. W., Hill, J. L., Owen, G., …Geary, A. P. (2019). Age and development of active cryoplanation terraces in the alpine permafrost zone at Svartkampan, Jotunheimen, southern Norway. Quaternary Research, 92(3), 641-664. https://doi.org/10.1017/qua.2019.41

Schmidt-hammer exposure-age dating (SHD) of boulders on cryoplanation terrace treads and associated bedrock cliff faces revealed Holocene ages ranging from 0 ± 825 to 8890 ± 1185 yr. The cliffs were significantly younger than the inner treads, which...

© 2018 Collegium Boreas. Published by John Wiley & Sons Ltd Rock-slope failures (RSFs) constitute significant natural hazards, but the geophysical processes that control their timing are poorly understood. However, robust chronologies can provide v...

Landform transitions from pronival ramparts to moraines and rock glaciers: A case study from the Smørbotn cirque, Romsdalsalpane, southern Norway (2016)
Journal Article
Matthews, J. A., Wilson, P., & Mourne, R. (2017). Landform transitions from pronival ramparts to moraines and rock glaciers: A case study from the Smørbotn cirque, Romsdalsalpane, southern Norway.

Landform transitions are defined as intermediate forms that represent transient developmental stages between conventional landform types. This study evaluates possible cases of landform transitions from pronival (protalus) ramparts to moraine ridges,...

Relict blockstreams at Insteheia, Valldalen-Tafjorden, southern Norway: Their nature and Schmidt-hammer exposure age (2016)
Journal Article
Wilson, P., Matthews, J., & Mourne, R. (2017). Relict blockstreams at Insteheia, Valldalen-Tafjorden, southern Norway: Their nature and Schmidt-hammer exposure age. Permafrost and Periglacial Processes, 28(1), 286-297. https://doi.org/10.1002/ppp.1915

Two small blockstreams, the first such landforms to be recorded in the mountains of Scandinavia, are described from Insteheia, a col at 910 m asl on the watershed between Valldalen and Tafjorden (Møre og Romsdal), southern Norway. Both blockstreams d... Read More about Relict blockstreams at Insteheia, Valldalen-Tafjorden, southern Norway: Their nature and Schmidt-hammer exposure age.

CATENA, 143, 35-44. https://doi.org/10.1016/j.catena.2016.03.018

An index of the degree of rock-surface microweathering based on Schmidt hammer R-values is developed for use in the field without laboratory testing. A series of indices - I2 to In, where n is the number of successive blows with the hammer - is first...
