The principal justification for the collision model has been the observation that continental rocks overlying the schists locally show transport to the northeast. Field and petrographic studies now confirm that the northeast movement occurred during exhumation of the schist, not during subduction. Combined with regional geologic relations, this evidence makes the collision model unlikely. This content is PDF only. Please click on the PDF icon to access.
