Quick Summary

The Delaware Basin is a geological feature located in western Texas and southeastern New Mexico, within the larger Permian Basin. It is a significant sedimentary basin known for its rich deposits of petroleum and natural gas.1

The basin's origins trace back to Precambrian tectonic events, with its structure developing through Paleozoic and later mountain-building periods. During the Permian Period, the Delaware Basin accumulated deepwater sediments, including organic-rich materials that became petroleum source rocks. Its margins were rimmed by reef-like carbonate buildups, which are now exposed in places like Guadalupe Mountains National Park. Later, restricted marine conditions led to the deposition of thick salt and gypsum layers. The Delaware Basin is one of three component parts of the Permian Basin, alongside the Midland Basin and the Central Basin Platform.1
