GLICK, SHERWOOD E. FKEZON, and MACKENZIE GORDON, JR. ABSTRACT The Witts Springs Formation is named for the village of Witts Springs in the Snowball quadrangle, north-central Arkansas. Its thickness ranges from less than 300 feet to nearly 600 feet in the quadrangle, where it rests unconformably in the Cane Hill Formation and is overlain unconformably by the Atoka Forma­ tion. At one locality in the southwestern part of the quadrangle, a post-Cane Hill channel cuts through the Cane Hill Formation; and the channel-fill fades of the Witts Springs rests on the Pitkin Limestone. The Witts Springs Formation is stratigraphically equivalent to the Prairie Grove Member of the Hale Formation and to the overlying Bloyd Shale, both of which have their type localities in northwestern Arkansas. The entire faunal assemblage of the Witts Springs is distinctly and typically Morrow. INTRODUCTION The rocks that overlie the Pitkin Limestone of Late Mississippian age hi the Snowball quadrangle, Newton and Searcy Counties, Ark. (figs. 1,2, 3), constitute three mappable units. The lowermost unit is as much as 320 feet thick in the quadrangle and contains fossils of lat­ est Mississippian age hi its lower 100 feet. Because of its mappability in the Snowball quadrangle (fig. 3), this unit is herein designated as the Cane Hill Formation (Pennsylvanian and Mississippian in age) rather than as the Cane Hill Member of the Hale Formation (Early Pennsylvanian in age in northwestern Arkansas), with which it is homotaxial.

Thus, Imo Formation is abandoned. The middle unit of the post-Pitkin sequence in the Snowball quad­ rangle, the subject of this report, is here designated the Witts Springs Formation. It is stratigraphically equivalent to the Prairie Grove Member of the Hale Formation and to the overlying Bloyd Shale of northwestern Arkansas. The new name is applied in the Snowball quadrangle because the Prairie Grove and Bloyd were not found to be individually mappable throughout the quadrangle. The Witts Springs is underlain by the Cane Hill Formation and overlain by the uppermost unit, the Atoka Formation.

WITTS SPRINGS FORMATION, "NORTH-CENTRAL ARKANSAS D5 TYPE SECTION The Witts Springs Formation is named for the village of Witts Springs in the south-central part of the Snowball quadrangle, Searcy County, Ark., near which it is exposed. Its type section is here designated as the section in the western head­ water branch of Calf Creek, which is 2 miles northeast of Witts 'Springs (figs. 4, 5). The base of the section is in the valley bottom in the Ny2NW%NE%NEV4 sec. 12, T. 13 N., R 18 W.

  • Brachiopods from the Mobarak Formation, North Iran
    GeoArabia, 2011, v. 16, no. 3, p. 129-192 Gulf PetroLink, Bahrain Tournaisian (Mississippian) brachiopods from the Mobarak Formation, North Iran Maryamnaz Bahrammanesh, Lucia Angiolini, Anselmo Alessandro Antonelli, Babak Aghababalou and Maurizio Gaetani ABSTRACT Following detailed stratigraphic work on the Mississippian marlstone and bioclastic limestone of the Mobarak Formation of the Alborz Mountains in North Iran, forty-eight of the most important brachiopod taxa are here systematically described and illustrated. The ranges of the taxa are given along the Abrendan and Simeh Kuh stratigraphic sections, located north of Damgham. The examined brachiopod species date the base of the Mobarak Formation to the Tournaisian, in absence of age-diagnostic foraminifers. Change in brachiopod settling preferences indicates a shift from high energy, shallow-water settings with high nutrient supply in the lower part of the formation to quieter, soft, but not soppy substrates, with lower nutrient supply in the middle part of the Mobarak Formation. Brachiopod occurrence is instead scanty at its top. The palaeobiogeographic affinity of the Tournaisian brachiopods from North Iran indicates a closer relationship to North America, Western Europe and the Russian Platform than to cold-water Australian faunas, confirming the affinity of the other biota of the Alborz Mountains. This can be explained by the occurrence of warm surface-current gyres widely distributing brachiopod larvae across the Palaeotethys Ocean, where North Iran as other peri- Gondwanan blocks acted as staging-posts. INTRODUCTION The Mississippian Mobarak Formation of the Alborz Mountains (North Iran) has been recently revised by Brenckle et al. (2009) who focused mainly on its calcareous microfossil biota and refined its biostratigraphy, chronostratigraphy and paleogeography.

This is one of many related papers that were included in the 1961 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly ac- quired facts in the field of anthropology, biology, geology, history, and technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the various subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related sub- jects. Bulletins are either octavo or quarto in size, depending on the the needs of the presentation. Since 1902, papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium.
