Structural Control Of Fluvial Network Morphology On Titan, Sarah Alice Drummond

Masters Theses

Titan fluvial networks have been classed based on identification of network pattern morphology. Drainage network patterns have specific geologic implications, as the pattern is affected by regional slope, structures, and bedrock resistance. Qualitative identification of network patterns has resulted in a lack of consistent classifications for networks. In this work, a global map of fluvial features on Titan is presented with features delineated based on their appearance in Cassini Titan Radar Mapper synthetic aperture radar (SAR) data. The networks imaged by the Huygens Descent Imager/Spectral Radiometer (DISR) are also included in this work. Networks were classified using a quantitative terrestrial …

Sedimentology And Allostratigraphy Of The Cardium Formation (Turonian-Coniacian) In Southern Alberta, And Equivalent Strata In Northern Montana, Joel Shank

Electronic Thesis and Dissertation Repository

The Turonian-Coniacian Cardium Formation of southern Alberta consists of marine sandstone and mudstone, deposited in a foreland basin over ~2.3 m.y. The formation thins from 150 m in the western foredeep to 50 m 350 km to the east. Correlation of 10 regional flooding surfaces in >1200 well logs and 25 outcrops provides an allostratigraphic framework. Mapping of two previously-unrecognized erosion surfaces (E5.2 and E5.5) reveals additional complexity within sandstone of the Raven River Member.

Facies successions coarsen upwards from thinly-bedded and bioturbated mudstone, to heterolithic facies (either bioturbated or bedded), to clean sandstone. Where conglomerate unconformably overlies this succession, …

Plate Kinematics Of The Afro-Arabian Rift System With An Emphasis On The Afar Depression, Helen Carrie Bottenberg

Doctoral Dissertations

This work utilizes the Four-Dimensional Plates (4DPlates) software, and Differential Interferometric Synthetic Aperture Radar (DInSAR) to examine plate-scale, regional-scale and local-scale kinematics of the Afro-Arabian Rift System with emphasis on the Afar Depression in Ethiopia. First, the 4DPlates is used to restore the Red Sea, the Gulf of Aden, the Afar Depression and the Main Ethiopian Rift to development of a new model that adopts two poles of rotation for Arabia. Second, the 4DPlates is used to model regional-scale and local-scale kinematics within the Afar Depression. Most plate reconstruction models of the Afro-Arabian Rift System relies on considering the Afar …
