New Mexico Geology Features Articles on Fossils, SE New Mexico

SOCORRO, N.M., Sept. 16, 2009 – The latest issue of the quarterly periodical New Mexico Geology features articles on invertebrate fossils from the Ghost Ranch area, and on oil and gas production from Mississippian-age reservoirs in southeast New Mexico.

The lead article is titled “Cenomanian invertebrate assemblage from the Dakota Sandstone near Ghost Ranch, Rio Arriba County, New Mexico.” The authors are Spencer G. Lucas and Larry F. Rinehart of the New Mexico Museum of Natural History and Science and Shari Kelley of the New Mexico Bureau of Geology and Mineral Resources. The authors describe how certain invertebrate bivalve and ammonite fossils may be used to identify the fossil-bearing strata as the Paguate Tongue of the Dakota Sandstone.

The second article is titled “Mississippian strata of southeastern New Mexico: distribution, structure, and hydrocarbon plays.” Writer Ronald F. Broadhead of the Bureau of Geology and Mineral Resources describes the oil and gas geology of areas in Lea, Eddy and Chaves counties.

The issue also contains abstracts of recent master’s theses and doctoral dissertations by students at New Mexico Institute of Mining and Technology, New Mexico State University and the University of New Mexico.
