APPARENT STRATIGRAPHIC CONCORDANCE OF REFLUX DOLOMITE: NEW INSIGHT FROM HIGH-FREQUENCY CYCLE SCALE SYNSEDIMéNTARY REACTIVE TRANSPORT MODELS

摘要

Reflux dolomite and coincident high-frequency cycle caps are often interpreted, by association, to have been generated by equivalent time-space events. We investigate this hypothesis using a reactive transport model to (i) evaluate geological, hydrological, and chemical controls on reflux dolomitization of a high-frequency cycle and (ii) explore intra- and intercycle episodic brine reflux during consecutive deposition of high-frequency cycles.
