Geologists observed the exposed rock types and structures (folds, faults, fractures) in the field, sampled the rock for microscopic(petrographic), chemical, and geochronological information, then used this information to develop a three dimensional model of the underlying bedrock and to understand the depositional and deformational history of Vermont. A bedrock map generally includes rock descriptions, age relationships (stratigraphic sequence), and major and minor structural data used to portray a three dimensional model of the rock on a two dimensional topographic base map.
Bedrock mapping to produce a new bedrock geological map of Vermont at a scale of 1:100,000. Incorporate the understanding of plate tectonic theory into the new map.
