DISCUSSIONS The Highland Border controversy: a discussion of “New evidence that the Lower Cambrian Leny Limestone at Callander, Perthshire, belongs to the Dalradian Supergroup, and a reassessment of the ‘exotic’ status of the Highland Border Complex”

Abstract

B. J. Bluck & J. K. Ingham comment: The status of the fossiliferous rocks at the Highland Border (the Highland Border Complex) has been a matter of speculation for over a century. The question has been whether the Highland Border Complex has affinities with the Dalradian block or constitutes a separate block, a sliver or slivers of which have been caught up along the Highland Boundary Fault.
