Since 1944, almost all the bedrock of the State has been mapped in a series of quadrangle maps on scales of 1:31,680 and 1:24,000. These were done under a cooperative project between the U.S. Geological Survey and the Khode Island Development Council and predecessor State agencies.
What kind of rock is Rhode Island made out of?
Geologic history. Rhode Island is the only state in New England formed entirely atop basement rock from the microcontinent Avalonia. The bedrock of Rhode Island first took shape with the emergence of a volcanic arc near a subduction on the margin of the supercontinent Gondwana, with the earliest rocks likely formed in the late Neoproterozoic.
