[1][2] The Yeso Group is lithologically complex, ranging from marine shelf carbonate rock to the south through shoreline and sabkha beds to eolian dune and sheet sand deposits to the north.

[9] Farther south, the group is divided into the Arroyo de Alamillo and Los Vallos Formations.

Production was limited from 1931 to 1980, but increased demand for carbon dioxide for enhanced oil recovery led to construction of pipelines to the Permian Basin.

Isotope studies suggest the carbon dioxide originated in the Earth's mantle and the Yeso Group is merely a reservoir rock.

[18] Baars pointed out in 1962 that the Meseta Blanca Member is indistinguishable from the De Chelly Sandstone,[4] but this redesignation was not widely accepted until the stratigraphic revisions of Lucas et al. in 2005, which also raised the formation to group rank.

[10] The promotion of the Yeso Formation to group rank and the abandonment of the Meseta Blanca Member remains controversial.
