The study of the effect of long term water cover on the mill tailings of the Silver Lake Mill # 1, near Silverton, Colorado.

Vardy, Renee L. (Wichita State University. Graduate School, 2009-05-01)

Mining and milling of metals were the primary industries in the study area for most of the late 1800's into theearly 1900's. Wastes from the mining and milling processes are abundant in the area and present significant ...
Depositional and structural history of the Sedgwick basin, South Central Kansas in relation to petroleum entrapment

Puyear, Jessica A.; Mazzullo, S. J. (Wichita State University. Graduate School, 2009-05-01)

The Sedgwick Basin is an important hydrocarbon producing area in Kansas. Subsurface structural and isopach (thickness) maps and cross-sections illustrate the depositional and tectonic history of the area. It has undergone ...
Paleoenvironmental interpretation of the bandera shale formation, marmaton group, desmoinesian stage, middle Pennsylvanian in southeastern Kansas.

Koch, Zach; Burke, C.D. (Wichita State University. Graduate School, 2009-05-01)

In southeastern Kansas and northeastern Oklahoma the Bandera Shale Formation (BSF) (Middle Pennsylvanian) crops out from Linn to Labette Counties in Kansas and in Nowata County, Oklahoma in units ranging from 12 cm to 20 ...
Nature and origins of a stratigraphic boundary in a continental setting, southern Bogda Mountains, NW China

Jeffrey, Brad M. (Wichita State University. Graduate School, 2010-04-23)

A nonmarine stratigraphic boundary where major facies shifts occur indicates drastic changes in environmental conditions, but may have highly variable magnitude of facies shifts to rapid lateral facies changes, common ...
Sources of upper Permian sedimentary rocks in the Bogda Mountains, NW China

Guan, Wei; Jeffrey, Brad M. (Wichita State University. Graduate School, 2010-04-23)

Both distant Tianshan suture zone and proximal local horsts are possible sources of Upper Permian sedimentary rocks exposed in the BogdaMountains. The Abundance of volcanic grains indicates the former was the main source. ...
Sedidmentology and diagenesis of Mississippian (Kinderhookian and Osagean: Tournaisian and Visean) reefs in southwest Missouri, northwest Arkansas, and northeast Oklahoma

Morris, Beau Tyler (Wichita State University, 2011-12)

Carbonate buildups (reefs) are present in the Kinderhookian Compton and basal Osagean Pierson formations in SW Missouri and adjoining Arkansas and Oklahoma. Their depositional origin, biota, and diagenesis are key to ...
Provenance analysis of Upper Permian-basal Triassic fluviallacustrine sedimentary rocks in the greater Turpan-Junggar Basin, southern Bogda Mountains, NW China

Guan, Wei (Wichita State University, 2011-12)

The Tian Shan region was identified as the source of Permian fluvial-lacustrine fills in the greater Turpan-Junggar basin. Thin-section petrographic study of thirty-six fine to very coarse lithic arenites from Upper ...
Late Atokan siliciclastic cave-fill deposits within preAbsarokan paleokarst in the Burlington-Keokuk limestone, Dade county, Missouri

Turner, Robert W. (Wichita State University, 2011-12)

Two siliciclastic-filled paleocaverns within the Mississippian (Osagean) Burlington- Keokuk Limestone, which were formed in pre-Desmoinesian (Middle Pennsylvanian) time, are described from exposures in Dade County, ...
Rift basin-fill architecture of fluvial-lacustrine Lower Permian Lucaogou and Hongyanchi low-order cycles, Bogda mountains, NW China

Jeffrey, Brad Marquis (Wichita State University, 2012-07)

Rapid lateral facies and thickness changes, autogenic processes, and irregular topography of nonmarine rift basins challenge the application of traditional marine sequence stratigraphic techniques. Stratigraphic architecture ...
Depositional patterns and stratal relationships on the distal margins of a foreland basin: Middle Jurassic Gypsum Spring and lower Sundance Formations, Bighorn Basin, WY

Gilbert, Clark (Wichita State University, 2012-12)

Depositional patterns and stratal relationships in the Middle Jurassic Gypsum Spring and lower Sundance Formations were influenced by a combination of paleotopographic highs and eustatic changes in the eastern Bighorn ...
