The Morrow Formation is a geologic formation from the Pennsylvanian geological age that is found in locations ranging from Southeast New Mexico and West Texas to locations in Oklahoma, Southwestern Kansas, and Arkansas.[1][2] It preserves fossils dating back to the Carboniferous period.
New Mexico Morrow Sands
The morrow formation is found in the Delaware Basin of southeastern New Mexico.
It can be found at depths of 8,200 to 12,500 feet. In some parts of southeast Eddy County and west areas of Lea counties, New Mexico, it may be found as deep as 15,000 feet.
Unique characteristics of this formation are:
- Limited areal extent (limited area to be found on a map)
- Wide variations of permeability

The Morrow facies (body of rock with specific characteristics) was deposited in a complex of mixed siliciclastic (mostly silica bearing rock) and carbonate depositional environments.[4]
Analogue to depositional process
In Prediction of reservoir geometries in the Morrow of southeastern New Mexico, the southern shelf of Belize, Central America is considered an analogue in the present time to the depositional process that had taken place in the Morrowan in SE New Mexico, during the time of the ancient Delaware Sea.[5]
