The central Kenya peralkaline province: Insights into the evolution of peralkaline salic magmas R. Macdonalda, and B. Scailletb aEnvironment Centre, Lancaster University, Lancaster LA1 4YQ, UK bISTO-CNRS, 1a rue de la Férollerie, 45071 Orléans cedex 2, France Abstract The central Kenya peralkaline province comprises five young (< 1 Ma) volcanic complexes dominated by peralkaline trachytes and rhyolites. The geological and geochemical evolution of each complex is described and issues related to the development of peralkalinity in salic magmas are highlighted. The peralkaline trachytes may have formed by fractionation of basaltic magma via metaluminous trachyte and in turn generated pantellerite by the same mechanism. Comenditic rhyolites are thought to have formed by volatile-induced crustal anatexis and may themselves have been parental to pantelleritic melts by crystal fractionation. -

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. INTRODUCTION of eastern Oklahoma, while most members of the Pteridaceae occur in Almost half of the ferns in the family western Oklahoma (Taylor & Taylor Pteridaceae are xeric adapted ferns. In 1991). Oklahoma six genera and sixteen species Statewide, the most common species in the family are known to occur. They in the Pteridaceae is Pellaea atropurpurea live on dry or moist rocks and can be (Figure 4), which can be found found in rock crevices, at the bases of throughout the body of the state and boulders, or on rocky ledges. Common Cimarron County in the panhandle. The associated species include lichens, mosses, rarest are Cheilanthes horridula and liverworts, and spike mosses. Two Cheilanthes lindheimeri. Cheilanthes horridula physical characteristics that unite the and Cheilanthes lindheimeri have only been family are the marginal sori (Figure 1) and seen in one county each, Murray and the lack of a true indusium. -

Volcanic activity took place periodically from the Late Miocene to the Holocene. -
Overview of Water and Related Resources Part 2
Overview of Water and Related Resources Part 2 Natural Resource & Socioeconomic Characteristics n almost endless array of environmental and socioeconomic characteristics -- including climate, geography, geology, minerals, soils, agriculture, wildlife, recreation, archeology, commerce population and employment -- which affect the current and future availability and use of Oklahomas surface and groundwater supplies. A CLIMATE Climate, along with geography, has a profound influence on water resources and hydrologic characteristics in Oklahoma, which lies across two divergent climatic regions. The states relatively long distance from the moderating effect of the oceans and an absence of mountains to the north often allows cold arctic winds to reach Oklahoma during the winter, which is normally short and mild. In the spring, large thunderstorms develop when warm, moist air from the Gulf of Mexico converges with colder northern, humid eastern and dry western air masses, often producing tornadoes and large hail. Summers in Oklahoma are usually long and hot, punctuated by droughts of varying degree and duration. Fall, though often wet, normally features mild days and cool nights. May ranks as the wettest month while January is the driest. Annual rainfall (Figure 7) varies from more than 50 inches in the relatively warm and humid pine forests of the Ouachita Mountains in southeast Oklahoma to approximately 16 inches in the high plains of the western Panhandle where warm days and cool nights predomi- nate. The state-averaged precipitation is 33.5 inches. The temperatures in Oklahoma (Figure 8) vary from approximately 54 to 62 degrees Fahrenheit from west to east with a state average of 60.5 degrees.
