A remarkably little-deformed sandstone in a roadcut near Karasjok showssedimentary structures characteristic of a subaerially exposed tidalenvironment. The fining upward sequence displays flaser bedding, parallellamination, mudclasts, bimodal cross bedding, and mudstone layers withshrinkage cracks. The sandstone is stratigraphically in about the centerof the Karasjok Greenstone Belt, and indicates a shallow-marine environmentfor at least some of the deposits.
