Structural Geology Trip to the Ouachita Mountains

People looking at folds. Faces obscured to protect identities. ¡Mas folding!. Action shot of man pointing at a fold Normal fault in sandstones and shales Recently, I got to join a field trip to the Ouachita Mountains to discuss a spectacular structural event that took place in the Late Paleozoic. The strata of the Ouachita Mountains are dominantly sandstone and shale beds from the Cambrian to the Pennsylvanian that were deposited in an offshore, deep water environment somewhat similar to the deep water regime of the Gulf of Mexico. Beginning in the Mississippian Subperiod, a compressional event initiated as proto-North America collided with a small land mass (volcanic arc) to the south creating the Ouachita Mountains, a...

The Fatal First Natural Gas Well in Southern Arkansas

Image
At 2:10 pm on Thursday, April 22, 1920, the small town of El Dorado, in Union County, Arkansas was busily going about its day. Over a dozen miles northwest, a drilling rig had just finished drilling the first productive oil well in Arkansas six days prior, the Hunter No. 1. However, just two miles [1]  southwest of town was another well being drilled that was going to make headlines as the first productive gas well in southern Arkansas.  Top left: land owners, Mr. and Mrs. Frank Hill. Center: the Hill No. 1 well blowing water, gas, and mud into the air. Bottom right: Constantine Oil and Refining geologist, J. J. Victor. [2] The Hill No. 1 well (Sec. 1, T.18S., R.16W.) operated by Constantine Oil and Refining Company of Tulsa, Oklahoma drilled to 2,226 feet, when it became an "unexpected 'gusher'" and a "great 'gasser'" [3] . The Monroe News-Star newspaper of Monroe, Louisiana reported that it received a kick (i.e. anomalous influx of...

Odd Stratigraphic Names

The USGS has a great website for searching stratigraphic names and I've found some names that are a little different. I've listed some of the most interesting ones below. Note that many of these are from the western states, and there's a reason for that. Names of lithostratigraphic units (groups, formations, members, and beds) must named after a geographic locality, such as a county, town, river, or mountain, per the nomenclatorial rules set forth in the North American Stratigraphic Code . Many of the geographic localities in the eastern US are more puritanical, if you will, from early European settlers, while the western states settled in the mid- to late-nineteenth century were named more loosely. Also, note that not all of these names are currently in use, some of these names may have been abandoned in favor of another name(s) and others may have been proposed, but not formally accepted for one reason or another (e.g. it must have sufficient reason for naming the unit,...
