“…D 1 involved north directed deformation that produced a pervasive foliation that is generally parallel to the lithologic layering along the transect. This event, which includes formation of most of the north directed fold‐thrust belt, probably spanned most of the Cretaceous and may have ended in the Aptian Vogl [2002]. The post‐D 1 structural history of the Brooks Range has been more highly debated.…”

“…The post‐D 1 structural history of the Brooks Range has been more highly debated. Recent structural mapping by Vogl [2002] has shed light on this history and is summarized as follows. Porphyroblasts overgrow the D 1 foliation in the deepest levels of the NGS zone (kyanite, chloritoid, or albite) and in the NEA zone (garnet, biotite, or chloritoid), indicating post‐D 1 heating.…”

“…Till and others (2008a) report that gneissic textures are particularly common where the unit is closest to metaplutonic rocks of the Arrigetch Peaks and Mount Igikpak orthogneiss (unit Dogn). Mafic rocks within the unit contain assemblages of the albite-epidote-amphibolite facies (Dusel- Bacon and others, 1989;Vogl, 2002); exposures west of the major orthogneiss bodies appear to be lower in grade (Nelson and Grybeck, 1980;Toro, 1998). Unit may, in part, represent a higher metamorphic grade equivalent of a number of units of the Brooks Range, including S_bs, Dbf, Degh, D_cs, and |<aqm.…”

“…Mull, oral commun., 2007). Large-magnitude Early to mid-Cretaceous extension of the overthickened orogen along shallow dipping, top-to-south normal faults has been documented in the southern Brooks Range (for example, Miller and Hudson, 1991;Blythe and others, 1996;Vogl, 2002;Vogl and others, 2002), but younger, top-to-north extensional collapse that could account for normal displacement of the Gilead succession on the north edge of the range has never been recognized. Alternatively, the missing Lower Cretaceous units could be absent due to local non-deposition or may have been removed by erosion (Schenk and Bird, 1993) or mass wasting before deposition of the Gilead sandstone.…”
