Stratigraphic Range

Ten newly recoveredDunbaritesspecimens significantly extend the known stratigraphic range ofDunbarites.These include the first documented Midcontinent Basin records of the Missourian type speciesDunbarites rectilateralis(Miller, 1930) from north-central Oklahoma. Additional species ofDunbaritesfrom south-central Oklahoma and north-central and West Texas are described asDunbarites wewokensisn. sp. andDunbarites boardmanin. sp. AlthoughDunbaritesis an extremely rare component (~0.025 percent) of Middle and Upper Pennsylvanian ammonoid assemblages, Ruzhencev and Bogoslovskaya (1971, 1978) suggested thatDunbaritesandParashumarditesRuzhencev, 1939 be used as genozone markers for the Kasimovian [Zhigulevian] Stage (Missourian in North America). As demonstrated by this report, the range ofDunbaritesis not confined to the Kasimovian, thereby precluding its use as a Kasimovian Stage indicator.

Discovery of the North Snyder reef in November, 1948 by the Standard of Texas focused the attention of the oil industry on this part of West Texas and presented the geophysicist with the problem of how to locate other reefs of this type. The North Snyder reef is unique in that reflected energy is obtained from the reef‐shale contact in some parts of the field. Magnetic, gravimetric and seismic data are presented to show some of the effects to be expected from a reef of this type. A number of electric log correlations are included in order to illustrate the geology of the field. From the electric logs it appears that the “draping” effect is small above the thick Pennsylvanian shale section which compensates for the reef mass. Contour maps for the base of the Coleman Junction limestone and the top of the Canyon reef are presented.
