Extract

Volker and Upton (VU) have provided an excellent contribution to the study of the Rhum complex, providing substantial amounts of descriptive material and new observationsto allow the discussion to rise above mere opinion. VU disagree with two of our (Bédard et al. 1988) principal conclusions about the genesis of the Eastern Layered Series. We argue in the following comment that, on the contrary, their data support and complement our conclusions.
