Abstract

Some 48 dolomite, 37 granite, and 19 limestone machine-polished disks were buried at soil horizon boundaries in 16 soil pits to maximum depths of 0.5-0.6 m within Kärkevagge, a presently periglacial, glaciated trough in Arctic Sweden. The objective of the ongoing study is to determine near-surface potential weathering rates beneath birch forest, Dryas heath, heath, meadow, solifluction meadow, and willow vegetation cover types. Selected disks were excavated after 1 year, and all disks were excavated after 4 or 5 years. Poor drainage and decreasing pH were found to promote dolomite weathering rates
