The Transition from Shelf Deposition to Deepening Associated with the Onset

The transition from shelf deposition to deepening associated with the onset of continental collision is marked by a change from

A) cross-bedded orthoquartzites and quartz pebblestones to stromatolitic shaly and cherty dolomites.
B) silty mudstone and turbidites to laminated and concretionary shale.
C) stromatolitic shaly and cherty dolomites to silty mudstone and turbidites.
D) laminated and concretionary shale to laminated shaly limestone with turbidites.
