The order in which the changes taking place in tectonic activity in the Martinsburg and Massanutten formation is:
- Erosion of the taconian mountains providing abundant carbonate sediment of the Massanutten formation.
- Taconian mountain building and the influx of siliciclastic sediment of the upper Martinsburg formation.
- Tectonic quiescence and the deposition of lime mud on carbonate platform of the upper Martinburg formation.
- Tectonic quiescence & the deposition of lime mud on carbonate platform of the Helderberg formation.
<h3>What order did the tectonic events happen?</h3>
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.

The fact that volcanic rock has often been found early in the rock record but less frequently in later rock layers suggest to scientists the following conclusion about early earth: <span>volcanic activity was more common in the past than it is today.
