Abstract
Woodson County in southeastern Kansas has been the scene of post-Douglas (Upper Pennsylvanian) intrusive igneous activity. Evidence of this is the presence of (1) an outcropping granite dike, (2) basic dikes or sills which were encountered by at least three drilled wells, and (3) hydrothermally metamorphosed rock in four separate bodies, one of which outcrops. The dikes and metamorphic rocks occur where the strata are folded into domes which are exceptionally sharp for Kansas. The writers suggest that the domal structure is due to the force of intrusion of magma into the deeper sedimentary rocks and that consequently these domes may properly be termed laccoliths.
