Structure and tectonics of the Hudson Valley fold-thrust belt, eastern New York State ( USA).

Analysis of structural features displayed in Silurian and Devonian strata of the Hudson Valley region indicate that these rocks form the W edge of a now largely eroded, W-verging, fold-thrust belt (the Hudson Valley fold-thrust belt, or 'HVB'). W of the Hudson River, remnants of this fold-thrust belt define a miniature valley and ridge province. Faults of the HVB die out to the W as blind thrusts in the basal units of the Catskill clastic wedge. The age of deformation and the tectonic setting of the HVB is enigmatic; its spatial relation to the Catskill clastic wedge and to Acadian metamorphic terranes suggests that the belt represents foreland shortening developed during the Acadian Orogeny.-from Author
