Geol. Survey Folio No. 3, 1900, p. 3) included the Massern Ranges (now called the Ouachitas), the Arbuckle Hills, and the Wichita Mountains.

POWEKS----AGE OE FOLDING OE OKLAHOMA M OUNTAINS Only the movements in Carboniferous time are considered. Earlier movements in southern Oklahoma, except, possibly, an upwarp of the western part of the Wichita Mountains, were of minor effect. In the Arbuckle Mountains the top of the Hunton limestone is in places missing and its absence indicates movement; in Texas there is a hiatus between the Silurian (Hunton?) and the Mississippian limestone (of Boone age) which indicates a movement in Llanoris, on the east. The earlier mountain systems were no doubt slightly different in posi­ tion and configuration from those now existing. The Ouachita géosyn­ clinal prism of accumulation, probably lay southeast of the present Ouachita Mountains. The beds were folded and afterward overthrust to the north. A hypothetical uplifted mountain mass, called the pre- Ouachita uplift, composed of rocks like those in the Arbuckle Mountains (or perhaps a part of the Arbuckle Mountains themselves), probably existed in Mississippian time where the present Ouachitas are. Originally the Arbuckle Mountains occupied a larger area than they do now, extending westward as far as Pauls Valley, northward beyond Seminole, and southeastward to Durant. The Wichita Mountain system extended eastward from the New Mex­ ico line to beyond Gainesville, Texas. Its north rim was a line of lime-" stone hills, most of them now buried, which ran from Gotebo past the Criner Hills. Its south rim, which was far more complex in structure and probably included several faulted anticlines, extended from Foard County, Texas, on the west, to and beyond Cooke County, on the east. A branch (the real south rim) ran northwestward past Nacona, Texas, and Waurika, Oklahoma. The Llano-Burnet, or “Central Mineral,” region is an area of gently folded and highly faulted Pennsylvanian and older rocks, which are overlapped on the south and east by Cretaceous beds and on the west and north by early and middle Pennsylvanian beds ; so that it represents only a fragment of a once extensive domal uplift, which rose like a horst and withstood fairly well the ravages of diastrophic movements, although it is now a topographic depression. The Bend Arch forms the north flank of the uplift. The Marathon region in Texas appears to show a western extension of the folding of the Oklahoma Mountains, while the Glass Mountains, but not the folds of the Marathon uplift, are related to the Ancestral Eocky Mountains. The Solitario dome is in the farthest southwest “window” of the Oklahoma Mountains. It is thought that the beds in the pre-Ouachita uplift, which are com­ posed of rocks like those of the Arbuckle Mountains and are now covered Downloaded from http://pubs.geoscienceworld.org/gsa/gsabulletin/article-pdf/39/4/1031/3414955/BUL39_4-1031.pdf by guest on 25 September 2021 INTRODUCTION

  • Four Western Cheilanthoid Ferns in Oklahoma
    Oklahoma Native Plant Record 65 Volume 10, December 2010 FOUR WESTERN CHEILANTHOID FERNS IN OKLAHOMA Bruce A. Smith McLoud High School McLoud, Oklahoma 74851 Keywords: arid, distribution, habitat, key ABSTRACT The diversity of ferns in some of the more arid climates of western Oklahoma is surprising. This article examines four Oklahoma cheilanthoid ferns: Astrolepis integerrima, Cheilanthes wootonii, Notholaena standleyi, and Pellaea wrightiana. With the exceptions of A. integerrima and P. wrightiana which occur in Alabama and North Carolina respectively, all four species reach their eastern limits of distribution in Oklahoma. Included in this article are common names, synonyms, brief descriptions, distinguishing characteristics, U.S. and Oklahoma distribution, habitat information, state abundance, and a dichotomous key to selected cheilanthoids. The Oklahoma Natural Heritage Inventory has determined that all but one (N. standleyi) are species of concern in the state.

'Radio-location telemetry was used to monitor coyotes throughout the study. Home range size, habitat use, and seasonal food habits were determined. ··lt Financial support was provided by the Oklahoma Department of Wildlife Conservation, Oklahoma State University Environmental Institute, Oklahoma State University School of Biological Sciences, Fort Sill Military Reservation of the U.S. Department of Defense, and the U.S. Fish and Wildlife Service. I express my appreciation to my major adviser, Dr. James H. Shaw, Assistant Professor of Wildlife Ecology, for initiation of this pro­ ject. I especially thank Dr. John A. Bissonette, Assistant Leader, Oklahoma Cooperative Wildlife Research Unit, for serving as committee chairman in the absence of Dr. Shaw and for his valuable comments dur­ ing the writing of thi.s thesis. I also thank Dr. Fritz L. Knopf, Assistant Professor of Wildlife Ecology; and Dr. Paul A.

    Rev. 08 STP 3 & 4 Final Safety Analysis Report 2.5S.1 Basic Geologic and Seismic Information The geological and seismological information presented in this section was developed from a review of previous reports prepared for the existing units, published geologic literature, interpretation of aerial photography, a subsurface investigation, and an aerial reconnaissance conducted for preparation of this STP 3 & 4 application. Previous site-specific reports reviewed include the STP 1 & 2 FSAR, Revision 13 (Reference 2.5S.1-7). A review of published geologic literature and seismologic data supplements and updates the existing geological and seismological information. A list of references used to compile the geological and seismological information presented in the following pages is provided at the end of Subsection 2.5S.1. It is intended in this section of the STP 3 & 4 FSAR to demonstrate compliance with the requirements of 10 CFR 100.23 (c). Presented in this section is information of the geological and seismological characteristics of the STP 3 & 4 site region, site vicinity, site area, and site. Subsection 2.5S.1.1 describes the geologic and tectonic characteristics of the site region and site vicinity. Subsection 2.5S.1.2 describes the geologic and tectonic characteristics of the STP 3 & 4 site area and site. The geological and seismological information was developed in accordance with NRC guidance documents RG-1.206 and RG-1.208. 2.5S.1.1 Regional Geology (200 mile radius) Using Texas Bureau of Economic Geology Terminology, this subsection discusses the physiography, geologic history, stratigraphy, and tectonic setting within a 200 mi radius of the STP 3 & 4 site.
