Near-Surface Shear-Wave Velocity Measurements in Unlithified Sediment
(University of Kansas, 2011-05-31)Shear-wave (S-wave) velocity can be directly correlated to material stiff¬ness making it a valuable physical property that has found uses in construction, engineering, and envi-ronmental projects. This study compares three ... -
Evaluation of high frequency vibrator response
(University of Kansas, 2012-08-12)Accurate analysis of the motion of a commercial high frequency hydraulic vibrator commonly used for near-surface applications demonstrated that the rigid body assumption of the weighted-sum approximation is not valid ... -
Geophysical Investigations of the Mound City Borrow Pits, Ross County, Ohio
(University of Kansas, 2012-05-31)Geophysical subsurface imaging is becoming a common practice in archaeology. Non-invasive geophysical methods provide efficient alternatives to costly and invasive excavations, allowing archaeologists to analyze sites ... -
Investigating the Diversity of Semionotid Fishes (Neopterygii: Semionotiformes) in the Upper Triassic Chinle Formation, Southern Utah
(University of Kansas, 2012-05-31)A new species of semionotiform fish is described based on specimens collected from the Upper Triassic Church Rock Member of the Chinle Formation. This new species of Semionotus is characterized by a deep body with a large ... -
Ichnotaxonomic assessment of Mazon Creek area trace fossils, Illinois, USA
(University of Kansas, 2010-08-12)The Francis Creek Shale Member (FCSM) of the Mid-Pennsylvanian Carbondale Formation along Mazon Creek in northern Illinois is known for soft-bodied organisms preserved within siderite concretions. Trace fossils, though ... -
Dissolved inorganic carbon in soil and shallow groundwater, Konza Prairie LTER Site, NE Kanas, USA
(University of Kansas, 2011-12-31)Sources and seasonal trends of dissolved inorganic carbon (DIC) in a shallow limestone aquifer were studied for 1 year at the Konza Prairie LTER (Long-Term Ecological Research) Site in northeastern Kansas, from spring 2010 ... -
Quantification of Ichnological, Paleoecological, Paleohydrological, and Paleoclimatological Information from the Upper Jurassic Morrison Formation
(University of Kansas, 2012-05-31)This dissertation takes a multifaceted approach to interpreting paleoenvironments and paleoclimate represented by the strata of the Morrison Formation (MF). The MF has been the subject of geological and paleontological ... -
Microtubules in hyaloclasts from the Hawaii Scientific Drilling Project #2 phase 1 core, Hilo, Hawaii: evidence of microbe-rock interactions
(University of Kansas, 2011-12-31)Minute tubules etched into basalt glass in hyaloclastites from the Hawaii Scientific Drilling Project #2 (HSDP) phase 1 borehole are interpreted as trace fossils formed by microbes, i.e. microendolithic borings. Such borings ... -
Heterozoan carbonate lithofacies and sequence stratigraphy: a study of Pliocene strata of the Agua Amarga basin, southeastern Spain
(University of Kansas, 2011-12-31)This study of Pliocene heterozoan carbonates in the Agua Amarga basin southeastern Spain seeks to increase understanding of factors controlling facies distribution and sequence stratigraphic stacking in heterozoan carbonates. ... -
Sequence-Stratigraphic Analysis of the Rollins and the Cozzette Sandstone Members, the Upper Cretaceous Mount Garfield Formation of the Piceance Basin, Colorado.
(University of Kansas, 2011-08-31)Sequence-stratigraphic study of the Cozzette and the Rollins Sandstone members, of the Mt. Garfield Formation of the Mesaverde Group, in the southern part of the Piceance basin (western Colorado), utilizes mainly well-log ... -
Biomarker and Paleontological Investigations of the Late Devonian Extinctions, Woodford Shale, Southern Oklahoma
(University of Kansas, 2011-12-31)The Late Devonian extinctions at the Frasnian-Famennian (F-F) boundary and the Devonian-Carboniferous (D-C) boundary were investigated in the Woodford Shale of southcentral Oklahoma with organic geochemical, bulk geochemical, ... -
ICHNOTAXONOMY AND PALEOENVIRONMENTAL ANALYSIS OF TRACE FOSSILS IN THE LATE DEVONIAN CATSKILL FORMATION, NORTH-CENTRAL PENNSYLVANIA, USA
(University of Kansas, 2011-12-31)The purpose of this thesis is to interpret the ichnotaxonomy, paleoenvironmental distribution, and paleoecological ramifications of trace fossils from the Frasnian to Famennian Catskill Formation (CF), north-central ... -
Timing of exhumation of the eastern Central Alps from zircon and apatite (U-Th)/He thermochronology (Graubünden, Switzerland)
(University of Kansas, 2011-12-13)The structurally complex eastern Central Alps, located in eastern Switzerland and adjacent areas, have helped constrain the timing and kinematics of deformation during the Alpine orogeny. Several regional and orogenic scale ... -
Thermochronometric analysis of the North Lunggar Rift: Implications for the timing of extension initiation and structural style of deformation in southern Tibet
(University of Kansas, 2011-01-01)Active north-trending rifts in southern Tibet are kinematically linked to conjugate sets of strike-slip faults along the Bangong-Nujiang Suture zone (BNS), but the initiation age of the strike-slip faults is currently ... -
Temporal and thermal evolution of extensional faulting in the central Gulf of Suez and detrital zircon (U-Th)/He constraints on the thermo-tectonic Paleozoic and Mesozoic history of the Sinai, Egypt
(University of Kansas, 2011-08-31)Many fundamental concepts of rifting have been influenced by observation made in the Gulf of Suez as a result of detailed structural and sedimentological studies. Although the three-dimensional structural geometry of the ... -
