Ordavician geological time period is the period of surface bedrock formation in Tug Hill Plateau region in New York.
Explanation:
The Tug Hill Plateau region is a high altitude elliptical-shaped plateau region in New York is formed with sedimentary surface bedrocks.
These sedimentary rock strata were horizontally underlain mostly during the middle to late Ordovician period over plateaus in this region. Sedimentary rocks like shale, limestone, dollostone, and standstone were sedimented as surface bedrocks in this location.
These are found like a veneer covering settled due to erosion and weathering processes. The erosions and weathering is mostly due to glacial depositions. The period of these rock formation dates back to about 410 million years ago.
