Tobago Volcanic Group (Trinidad and Tobago) |
The Tobago Volcanic Group is a geologic group in Trinidad and Tobago. It preserves radiolaria and ammonite fossils dating back to the Albian period. The formation contains the Bacolet Formation and comprises organic-rich, black pyritic siliceous mudstones and fine-grained volcaniclastic sandstones and siltstones.[1]
