Capitol Reef National Park National Park Service U.S. Department of the Interior Geology “Geology knows no such word as forever.” —Wallace Stegner Capitol Reef National Park’s geologic story reveals a nearly complete set of Mesozoic-era sedimentary layers. For 200 million years, rock layers formed at or near sea level. About 75-35 million years ago tectonic forces uplifted them, forming the Waterpocket Fold. Forces of erosion have been sculpting this spectacular landscape ever since. Deposition If you could travel in time and visit Capitol Visiting Capitol Reef 180 million years ago, Reef 245 million years ago, you would not when the Navajo Sandstone was deposited, recognize the landscape. Imagine a coastal you would have been surrounded by a giant park, with beaches and tidal flats; the water sand sea, the largest in Earth’s history. In this moves in and out gently, shaping ripple marks hot, dry climate, wind blew over sand dunes, in the wet sand.

Shallow-Crustal Metamorphism During Late Cretaceous Anatexis in the Sevier Hinterland Plateau: Peak Temperature Conditions from the Grant Range, Eastern Nevada, U.S.A
Shallow-crustal metamorphism during Late Cretaceous anatexis in the Sevier hinterland plateau: Peak temperature conditions from the Grant Range, eastern Nevada, U.S.A. Sean P. Long1*, Emmanuel Soignard2 1SCHOOL OF THE ENVIRONMENT, WASHINGTON STATE UNIVERSITY, PULLMAN, WASHINGTON 99164, USA 2LEROY EYRING CENTER FOR SOLID STATE SCIENCE, ARIZONA STATE UNIVERSITY, TEMPE, ARIZONA 85287, USA ABSTRACT Documenting spatio-temporal relationships between the thermal and deformation histories of orogenic systems can elucidate their evolu- tion. In the Sevier hinterland plateau in eastern Nevada, an episode of Late Cretaceous magmatism and metamorphism affected mid- and upper-crustal levels, concurrent with late-stage shortening in the Sevier thrust belt. Here, we present quantitative peak temperature data from the Grant Range, a site of localized, Late Cretaceous granitic magmatism and greenschist facies metamorphism. Twenty-two samples of Cambrian to Pennsylvanian metasedimentary and sedimentary rocks were analyzed, utilizing Raman spectroscopy on carbonaceous material, vitrinite reflectance, and Rock-Eval pyrolysis thermometry. A published reconstruction of Cenozoic extension indicates that the samples span pre-extensional depths of 2.5–9 km. Peak temperatures systematically increase with depth, from ~100 to 300 °C between 2.5 and 4.5 km, ~400 to 500 °C between 5 and 8 km, and ~550 °C at 9 km. The data define a metamorphic field gradient of ~60 °C/km, and are corroborated by quartz recrystallization microstructure and published conodont alteration indices. Metamorphism in the Grant Range is correlated with contemporary, upper-crustal metamorphism and magmatism documented farther east in Nevada, where metamorphic field gradients as high as ~50 °C/km are estimated. -

FOSTER Museum of Western Colorado, P.O. Box 20,000, Grand Junction, CO 81502; [email protected] A trilobite pygidium, likely referable to the genus Bonnima, is the first evidence of a member of the Corynexochida reported from the Lower Cambrian (Dyeran Stage) Chambless Limestone of the southern Marble Mountains in the Mojave Desert of California. This specimen represents the first occurrence of the family Dorypygidae in the cratonic facies of the Lower Cambrian in the California-western Nevada region, as all of the few previous reports of the family (mostly Bonnia) have been from much thicker, more distal open-shelf deposits far to the northwest in the White- Inyo—Esmeralda County region of California and Nevada. Although still relatively rare, the occurrence of Dorypygidae across a range of environments biofacies realms in this area is typical of their distribution in other regions.

Flood Surfaces and Deflation Surfaces Within the Cutler Formation and Cedar Mesa Sandstone (Permian), Southeastern Utah
Flood surfaces and deflation surfaces within the Cutler Formation and Cedar Mesa Sandstone (Permian), southeastern Utah RICHARD LANGFORD 1 „ „ . tr, , . „ , . „ . , rr . r , , , . 0,,,, MARJORIE A CHAN J Department of Geology and Geophysics, University of Utah, Salt Lake City, Utah 84112 ABSTRACT of dune masses and intervening interdune deposits results in the formation of first-order bounding surfaces (Mckee and Moiola,1975; Brookfield, Areally extensive erosion surfaces in eolian deposits have been 1977; Rubin and Hunter, 1982). First-order surfaces are limited in areal interpreted as long hiatuses in eolian deposition. Such erosion surfaces extent (several square kilometers) and form during relatively continuous form during deflationary episodes or during periods of erg stabiliza- eolian deposition. tion or contraction). They are called "super surfaces" and can be useful for stratigraphic correlation because of their regional extent. TOie Permian Cedar Mesa Sandstone and Cutler Formation con- tain a type of super surface (herein termed "flood surfaces"), -10-400+ tan2. Flood surfaces form as a result of fluvial floods into active dune seas. The surfaces may expand through nonclimbing mi- gration of eolian dunes but do not imply long hiatuses in eolian deposi- tion as do other types of super surfaces. Cutler and Cedar Mesa flood surfaces are overlain by shales and sandstones which thicken laterally and merge with fluvial channel-fill deposits. Flooding of active dune fields in the Cedar Mesa Sandstone is suggested by intertonguing of eolian dune and fluvial deposits. Flood surfaces can easily be mistaken for deflationary super surfaces but are distinguished by evidence of dune migration coincident with flood events and by an increase in the number of surfaces adjacent to associated aqueous deposits.
