Abstract

The trend of the post-Taconic Appalachian fold-thrust belt changes at the city of Kingston in the New York recess. To the south-west of Kingston, fold-thrust structures trend northeast-southwest, whereas to the north of Kingston, fold-thrust structures trend due north to north-northeast. This paper discusses the structural geometry and origin of this change in trend. We suggest that the bend at Kingston is an intersection orocline created when northeast-southwest-trending structures of the Kittatiny-Shawanguk segment of the Appalachian fold-thrust belt overprinted and reoriented older north-south-trending structures of the Hudson Valley fold-thrust belt. Calcite twin strain-gauge measurements indicate that there was less than 2% penetrative tangential stretching accompanying the development of this orocline. -from Authors
