The anticlinical theory of oil and gas
(University of Kansas, 1915) -
Estimating fault slip rates in the Himalaya and Tibet over 10 - 10^6 year timescales
(University of Kansas, 2012-12-31)The Himalayan-Tibetan orogen is the highest on the modern Earth and an archetypal region for studying continental collisions. As such, its characteristics have been the basis for many different models for orogenesis, in ... -
The Pennsylvanian of the San Juan Basin.
(University of Kansas, 1921) -
The oolites of Kansas City and their fauna
(University of Kansas, 1915) -
DEPOSITIONAL AND PALEOENVIRONMENTAL SETTINGS OF CRETACEOUS LIMESTONES IN THE GREATER ANTILLES
(University of Kansas, 2014-12-31)The first part of this research examines uncertainties surrounding the middle Cretaceous Antillean rudist biostratigraphy from fossiliferous limestones in the Greater Antilles and adds chemostratigraphic controls to constrain ... -
Ethnic differences in medicinal plant use among University students: a cross-sectional survey of self-reported medicinal plant use at two Midwest Universities
(BioMed Central, 2015)Background Numerous surveys of medicinal plant use among college students abound, but none compare use between students enrolled in two different Universities with significantly different ethnic compositions. The objective ... -
Effect of flow rate on clogging processes in small diameter aquifer storage and recovery injection wells
(University of Kansas, 2014-12-31)This study investigates injection well clogging at low injection rates (<0.38 m3/ min or 100 gpm) through laboratory column experiments and geochemical analyses. Clogging in recharge wells is a major concern for aquifer ... -
Characterizing the Groundwater-Surface Water Interactions in Different Subsurface Geologic Environments Using Geochemical and Isotopic Analyses
(University of Kansas, 2014-12-31)Shallow aquifers located near streams can be affected by groundwater contamination as a result of recharge from surface water; however, stream stage variation, subsurface geology, and seasonal changes can alter the magnitude ... -
High-resolution quantification of groundwater flux using a heat tracer: laboratory sandbox tests
(University of Kansas, 2014-12-31)Groundwater flux is the most critical factor controlling contaminant transport in aquifers. High-resolution information about groundwater flux and its variability is essential to properly assessing and remediating contamination ... -
Analysis of Chemical Storage and Transit Times to Characterize Water Movement Through a Thick Unsaturated Zone Overlying the High Plains Aquifer, Northwestern Kansas
(University of Kansas, 2014-12-31)The High Plains aquifer (HPA) is one of the largest aquifers in the world and is critical for agricultural production in both the United States and Kansas. Irrigation has had a large-scale effect on the water resources ... -
The Effect of Point Velocity Probe Size on Groundwater Velocity Estimation in Noncohesive Sediments
(University of Kansas, 2014-12-31)The point velocity probe (PVP) was developed to make in situ measurements of groundwater velocity in unconsolidated sediments and has been tested both in the laboratory and in the field. The purpose of this study was to ... -
Fluvial to shelfal strata of the Late Cretaceous to Paleogene Dorotea and Tres Pasos Formations, Magallanes Basin, El Calafate, Argentina
(University of Kansas, 2014-12-31)Late Cretaceous to Paleogene strata of the Tres Pasos and Dorotea formations, exposed along the Andean margin in the Santa Cruz Province of Southern Argentina, were deposited in the Magallanes Basin, a retro-arc foreland ... -
The taxonomy and taphonomy of fossil spiders from the Crato Formation of Brazil
(University of Kansas, 2014-12-31)In order to develop a clearer picture of the paleoenvironment of the Crato Formation, an early Cretaceous Fossil-Lagerstätte, the taphonomy and taxonomy of fossil spiders were examined. The Crato Formation is represented ... -
Ground-penetrating radar imaging of fluid flow through a discrete fracture
(University of Kansas, 2014-12-31)Predicting groundwater flow and transport of contaminants in fractured rock is challenging due to the heterogeneity of hydraulic properties that are difficult to characterize using conventional hydraulic testing methods. ... -
Shallow seismic reflection section—Introduction
(De Gruyter, 1998-01-01)For those interested in shallow seismic reflection (SSR) techniques, this special issue of Geophysics is likely to serve as a useful reference for years to come. The idea for this issue grew out of discussions that took ... -

Isotopic Disequilibrium among Commingled Hybrid Magmas: Evidence for a Two-Stage Magma Mixing-Commingling Process in the Mt. Perkins Pluton, Arizona
(University of Chicago Press, 1995-09-01)See article for abstract. -
Geochemistry of Mafic Magmas in the Hurricane Volcanic Field, Utah: Implications for Small‐ and Large‐Scale Chemical Variability of the Lithospheric Mantle
(University of Chicago Press, 1999-07-01)Low‐silica basanite, basanite, and alkali basalt lava flows and cinder cones make up the late Quaternary Hurricane volcanic field (HVF) in the Colorado Plateau/Basin and Range transition zone of southwestern Utah. Strombolian‐ ... -
A High Precision Aeromagnetic Survey Near the Glen Hummel Field in Texas; Identification of Cultural and Sedimentary Anomaly Sources
(Society of Exploration Geophysicists, 1997-01-01)We present a case study of a high resolution aeromagnetic survey near the Glen Hummel oil field (Figure 1). The survey was originally flown to support a study of aeromagnetic methods for environmental hazard detection, but ...
