Question

Stop 6: Putting it all together. How does the transition in sediment composition seen from the lower to upper Martinsburg formation compare to the sediment transition change between the Massanutten formation and overlying Helderberg Group? What does this tell us about the changes taking place in tectonic activity? Put the events in order that tell this story.

Answer 1

The order in which the changes taking place in tectonic activity in the Martinsburg and Massanutten formation is:

1. Erosion of the taconian mountains providing abundant carbonate sediment of the Massanutten formation.
2. Taconian mountain building and the influx of siliciclastic sediment of the upper Martinsburg formation.
3. Tectonic quiescence and the deposition of lime mud on carbonate platform of the upper Martinburg formation.
4. Tectonic quiescence & the deposition of lime mud on carbonate platform of the Helderberg formation.

What order did the tectonic events happen?

As a result of the erosion of the teconian mountains, there was abundant carbonate for the Massanutten formation.

Some time later, a process of tectonic quiescence led to a deposition of lime mud on the upper Martinsburg formation, and then the Heiderberg formation.
