The 3D line shown above is from the Wayne County area of southeast Mississippi, an area where numerous deep salt ridges and turtleback anticlines dominate the Jurassic structural setting. Hydrocarbons have been discovered and produced from both crestal and flank traps developed along the ridges and "turtles". Data courtesy Seismic Exchange.

Workover Rig at Wellsite

Pre-loess porphyritic rhyolite cobble clast exhibiting typical flow-banding structures. The phenochrysts visible in this specimen have been badly weathered resulting in pitting on the outer surfaces. The presence of unusual clasts like this can help differentiate the Pre-loess Terrace Deposits of the ancestral Mississippi River from the Pliocene Terrace Deposits in Southwest Mississippi. This specimen is from Clear Creek, a tributary of the Big Black River in Warren County, near the town of Bovina.
