Record #187458:

Weathering processes and Quaternary origin of an alpine blockfield in Arctic Sweden / Bradley W. Goodfellow, and 3 others.

Title: Weathering processes and Quaternary origin of an alpine blockfield in Arctic Sweden / Bradley W. Goodfellow, and 3 others.
Author(s): Goodfellow, Bradley W.
Date: 2009.
In: Boreas. (2009.), Vol. 38(2) (2009)
Abstract: Investigates weathering and origin of autochthonous blockfield in northern Swedish mountains through examination of fine matrix and clasts from two pits excavated across ridge-top sorted circles (one on summit and one in saddle). At summit, fine matrix chemical weathering is limited to production of poorly crystallised Al- and Fe-oxyhydroxides, whereas some additional vermiculitisation and gibbsite crystallisation occurs in saddle. In both locations volumes of clay-sized matrix are low, mass balance calculations indicate only minor elemental losses and no chemically etched grains are visible under scanning electron microscope.
