No conflict just a factor I did not know about. Thee water in both areas would have erupted from underground and originally would not have been acidic. What cause the water to turn acidic would have been suffer from all the volcanism at the time. They clay minerals would have formed before the water became acidic. The sulfur dioxide, and hydrogen sulfide probably seeped in to the rock after it had formed. So rather there than a conflict it actually fits the catastrophic model better than I first thought. Thanks.
