A family of asymmetric, northwest-verging back folds and crenulations occur on a regional scale in the Caledonian decollement zone in southwestern Norway. They are the result of reversal of the emplacement movement of the Jotun and other nappes in Ea

New 40Ar/39Ar thermochronologic data from the internal zone of the Penokean orogen in east-central Minnesota indicate rapid cooling from mid-crustal temperatures. Early Proterozoic metamorphosed cover rocks yield concordant hornblende and biotite pla

Archean metasedimentary rocks of the South Snowy Block of the Beartooth Mountains, in the vicinity of Jardine, Montana, consist predominantly of schistose rocks (interpreted as metamorphosed turbidities) with rare iron formation. These rocks are intr

Strain has been measured from clasts within a deformed conglomerate layer at 17 localities around an asymmetric fold in the Rundemanen Formation in the Bergen Arc System, West Norwegian Caledonides. Strain is very high and a marked gradient in strain

A bedding-parallel foliation exists in an area of multiple deformation in the Early Proterozoic Thomson Formation of Minnesota. Comparison of strain measurements in a region where the bedding-parallel foliation occurs with those from an area where it

The Penokean orogeny was a major early Proterozoic (1875-1825 Ma) tectonic event in the Great Lakes region. In east-central Minnesota, it is marked by multiply deformed and highly metamorphosed supracrustal rocks of the early Proterozoic Denham and T

The orientations of joints were measured at 142 locations across the northern Michigan Basin in rocks of Cambrian to Devonian age. Four major vertical joint sets were found throughout the area. The average trends of the four sets are 052°, 134°, 09

Two major phases of early Proterozoic Penokean folding are now recognized in the Thomson Formation of east-central Minnesota. Effects of the first deformation are found only in the southern two-thirds of the exposed Thomson Formation; the second defo
