The best evidence of multiple geologic periods represented in Virginia is the diverse rock formations and fossil records found throughout the state. Virginia's geological history spans from the Precambrian to the Cenozoic era, showcasing a variety of sedimentary, igneous, and metamorphic rocks. The presence of fossils, such as those from the Paleozoic era in the Valley and Ridge province, and Mesozoic dinosaur remains in the Coastal Plain, further supports the state's rich geological timeline. Additionally, the varying landscapes, including mountains and coastal plains, reflect the complex geological processes that have shaped Virginia over millions of years.
The presence of fossils of different ages
Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
The planet Earth is about 4,600 million years old. Fossil evidence becomes abundant in the geological record in the Cambrian Era, which was about 550 million years ago (when hard shelled animals appeared) Therefore (550/4600)*100 = roughly 12% of Geological time contains abundant fossil evidence. However, please note that (non abundant) fossil evidence goes back about 3600 million years, (3600/4600)*100 = roughly 73% of Geologic time.

540 Million years ago
The abundant fossil evidence appeared in the geologic record around 541 million years ago during the Cambrian period when complex organisms started to evolve. This sudden appearance of diverse life forms is known as the Cambrian explosion.
There were many floods. Almost every geologic layer was caused by a flood.
The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
I am a geologist and I know of no theory of "geologic evolution". "Evolution" as defined by Darwin describes the origin of species based on the survival of the fittest. This certainly can not be applied to geological processes, although life is integral to geology.
