Cross- stratification trends and cobble studies suggest a south­ eastern source for the material. A southwestern source direction is also postulated by the presence of Kaibab fossils, gray quartzite, and granite cobbles. The possibil­ ity exists that the granite and quartzite are from the Brad- shaw Mountains near Prescott. Coarse clastic facies in the Lower member of the Chinle show a decrease in quantity and grain size toward the northwest, correlating with the Shinarump findings. Another notable change is the thinning out and disappearance of some of the cliff-forming Upper Chinle units as they are traced southeastward from Leupp to Smith Butte. The most useful feature for stratigraphic control in the area is a resistant, cliff-forming, porcellanlte bed, found at the base of the Owl Rock, the uppermost member of the Chinle.formation. Some of the "limestones" of the Chinle formation in the area were found to be true limestones, but others are marlstones and porcellanites. The lime is believed to have vii been precipitated by evaporation from shallow, flood plain, lake waters. The soluble salts may have been flushed out by vraters from associated streams during flood stage. The silica responsible for the highly siliceous nature of cer­ tain Owl Rock units is believed to have been released by the decomposition of reworked volcanic ash and its conversion into montmorillonite. Silica carried by groundwater possib­ ly enriched the already siliceous rocks. The chert is secondary. Some substantiating evidence is offered for the concept of the Shinarump as a regressive, blanket deposit, and the Chinle as transgresslve, upward building deposit. vlli INTRODUCTION The Colorado Plateau, which includes the Leupp- Holbrook area, was first explored in 1540 "by Coronado and in 1776 by Escalante and other padres. The first geologist to visit the area described in this paper was Marcou (1856) who accompanied Lt. Whipple 011 his 1853 expedition to locate a transcontinental railroad route. Their party skirted the south edge of the region, following approximately the route used today by the Sante Pe railroad. The first geologist to actually traverse the Painted Desert was Newberry (1861) who was geologist of the expedition led by Lt.

This is one of many related papers that were included in the 2021 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. 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, Color Plates, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

U.S. Highway 89 leads south toward the entrance to Grand Canyon National Park and Flagstaff. For a route description along U.S. Highway 89 northward from here see HW-89A Road Guide.. The road junction is in the Petrified Forest Member of the Chinle Formation. The member is composed of interbedded stream channel sandstone and varicolored shale and mudstone. This member erodes moderately easily and forms the strike valley to the north and south. From here the route of this guide leads upsection into younger and younger beds of the Chinle Formation. 0.7 Cross Hamblin Wash and rise from the Petrified Forest Member into the pinkish banded Owl Rock Member of the Chinle Formation. The upper member forms pronounced laminated pinkish gray and green badlands, distinctly unlike the rounded Painted Desert-type massive badlands of the underlying member. 1.6 Road rises up through the upper part of the Chinle Formation, a typical wavy to hummocky road. Highway construction is easy across the slope-forming parts of the formation, but holding the road after construction is difficult because the soft volcanic ash-bearing shales heave under load or after wetting and drying.

Moenkopi Formation strata disconformably overlie Middle Permian (Guadalupian) limestones and dolomites of the San Andres Formation and are mostly grayish red, trough-crossbedded and ripple-laminated micaceous litharenites intercalated with beds of intraformational conglomerate and grayish red, micaceous siltstone and mudstone. Charophytes, ostracods and capitosauroid amphibians indicate the Moenkopi Formation in the Lucero uplift is of Middle Triassic (early Anisian) age. Overlying Chinle Group strata consist of (ascending) the Shinarump, Bluewater Creek, Petrified Forest, Owl Rock and Rock Point Formations. In the Lucero uplift, strata of the San Pedro Arroyo Formation laterally replace Bluewater Creek Formation strata south of the Rio Salado. Shinarump Formation strata are extrabasi­ nal conglomerates (mostly Paleozoic limestone clasts) and sandstones as much as 17 m thick that discon­ formably overlie Moenkopi strata. Locally, pedogenically modified sandstones, conglomerates and siltstones - the "mottled strata" laterally replace Shinarump conglomerates and sandstones. Bluewater Creek Formation strata are at least 70 m thick and are mostly reddish brown siltstones, mudstones and ripple-laminated sand­ stones The distinctive McGaffey Member - 5-6 m of mostly ripple-laminated sandstone is present in the upper half of the Bluewater Creek Formation in the northern part of the Lucero uplift.

  • A Fossil Locality Predictive Model for the Early Cretaceous Cedar Mountain Formation, Utah, Usa

Pope Date Dean of Graduate School Date A Fossil Locality Predictive Model for the Early Cretaceous Cedar Mountain Formation, Utah, USA Abstract Hard work and chance are nearly always among the deciding factors in finding new, important, and productive paleontological localities. Fossil locality predictive models have the potential to reduce unproductive field time and maximize hard work thus increasing the chances researchers have to find important localities. This study uses remotely sensed data to design and test a fossil locality predictive model for the Early Cretaceous Cedar Mountain Formation. Landsat 8 OLI/TIRS data from known localities were summarized, reclassified and used in a weighted suitability analysis to categorize fossil locality potential of the study area. Field work was conducted to test model functionality. Field observations were used to refine the weighted suitability analysis. Landsat 8 OLI/TIRS data alone offers a less accurate prescription of fossil locality potential. Additional physical and environmental factors play a role in determining the chance of finding fossils. Slope degree and aspect data from known localities were summarized and analyzed to further refine the model.
