Midnight Volcano is believed to be a buried
extinct volcano in southern
Humphreys County , Mississippi. It is named after the nearby town of
Midnight, Mississippi . During the time it was active, Midnight Volcano may have been a volcanic island in the
Mississippi Embayment .
[1]
The volcanic activity in the area is associated with the
Monroe Uplift ,
[2]
[3] and igneous rocks in the region have been dated from 84 to 73
Ma .
[4] A well drilled in Humphreys County found around 600 m (2000 ft) of volcanic rock, starting 1110 m (3641 ft) below the surface at the shallowest.
[5] The most recent measured volcanic rock was dated to 66 Ma,
[6] while older (and deeper) samples were dated at 81 and 94 Ma.
[7]
These most recent deposits roughly coincide with the activity of
Jackson Volcano , another buried volcano southeast of Midnight
[8]
Volcanic debris from this volcanism was also found in the "Coffee sands", a Cretaceous sand layer to the north.
