Submarine plateau volcanism and Cretaceous Ocean Anoxic Event 1a : geochemical evidence from Aptian sedimentary sections

Creator:

Walczak, Paul S.

Abstract:

Marine sediments exceptionally rich in organic carbon, known as black shales, occur globally but intermittently in well correlated Cretaceous successions. The presence of black shales indicates that sporadic, ocean-wide interruption of normal respiration of marine organic matter during oxygen-deficient conditions has occurred. Submarine volcanism on a massive scale, related to...
