About The Product

Published via the yankee Geophysical Union as a part of the Field journey Guidebooks Series.

Fold-thrust belts have many attributes in universal, yet a few of the vital attributes differ vastly. the aim of this box journey is to envision the diversity of version of numerous vital attributes of fold-thrust belts, together with (1) the tectonic surroundings of deposition of the allochthonous sedimentary rocks, (2) the presence or absence of crystalline basement rocks within the allochthon, (3) the stratigraphic point of the basal decollement, (4) the geometry and inner constitution of thrust sheets, and (5) the consequences of basement constructions underneath the allochthon at the geometry and kinematics of the fold-thrust belt. 4 areas in North American fold-thrust belts (Fig. 1-1) are visited in this box journey to check the variety of edition within the indexed attributes. The 4 areas are (1) the Alabama Appalachians (the southernmost exposures of the Appalachian orogen), (2) the Ouachitas (exposures within the Ouachita Mountains in Arkansas and Oklahoma), (3) the Idaho-Wyoming Rockies (exposures of the Cordilleran fold-thrust belt), and (4) the Montana Rockies (exposures of the frontal a part of the Cordilleran fold-thrust belt and basement constructions of the Rocky Mountain foreland).
