The Great Valley Sequence is located near the Sacramento region and is comprised of several formations. The formations that make up the Great Valley Sequence run from the Jurassic to the Cretaceous ages. The original deposition of sedimentary rock occurred during the late Mesozoic Era. The specific location of the Great Valley Sequence is very unique; it lies between the Franciscan Assemblage and the Sierra Nevada volcanoes.To better understand the geologic history of the Great Valley Sequence, I would want to request three different pieces of information and/or data about the area. In the Great Valley Sequence, there is a rock at Lake Berryessa made up of Turbidites in the Venado Sandstone. Turbidites are geologic deposition that distribute clastic sediments into deep ocean. It's very interesting how the Great Valley Sequence was formed by turbidity currents which is a type of sediment gravity flow.
The three pieces of information are: 1) Formation/Development: What type of tectonics plates are located in the area in which created the Great Valley Sequences? 2) Age: What types of fossils (if any) can be found in the Great Valley Sequence? 3) Deposition: What was the deposition of sedimentary like over the many years that has passed? With these three different pieces of information about the Great Valley Sequence, I think I would be able to have a better understanding about the areas relative dating. I would have a clearer understanding of what types of species lived within that period of time I would also have a clearer understanding on how the Great Valley Sequence developed over that period of time.
