When magma reaches the surface gases bubble, often explosively, out of it.
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.
