Investigation of a Novel Application of Optically Stimulated Luminescence (OSL) for Sediment Fingerprinting 

Hicks, Taryn (2023-04-26)
Optically Stimulated Luminescence (OSL) is a tool that is commonly used to measure the length of time a quartz or feldspar grain has been buried in a sediment deposit. Recently there have been advances in using OSL as ...

Limitations of the Microtremor Method: A Case Study in the Los Angeles Basin, California 

Bose, Deblina (2010-08-02)
Microtremor data from 16 broadband seismic stations across the Los Angeles basin are used to explore limitations of Nakamura's (1989) method for estimating resonant frequencies, amplification, and ground vulnerability to ...

Magmatic Processes and Conditions of Ashikule Volcanic Cluster, NW Tibetan Plateau 

Speetjens, Sara (2023-11-21)  ETD File Embargoed
Although magmatism at mid-ocean ridges and subduction zones are reasonably well understood, our understanding of magmatic processes beneath thick continental plateaus is lacking. On the northwestern Tibetan Plateau, the ...

Mineralogical and geochemical profiling of arsenic-contaminated alluvial aquifers in the Ganges-Brahmaputra floodplain Manikganj, Bangladesh 

Shamsudduha, Mohammad (2007-08-15)
The present study investigated three major components – groundwater, sediment and minerals of arsenic-affected Quaternary alluvial aquifers in Manikganj town, which is located in one of the As-hotspots in central Bangladesh. ...

Modeling the Effects of Projected Sea Level Rise on Water Quality in Coastal Bangladesh 

Shuman, Morgan (2015-05-04)
Climate models show that Bangladesh will experience high rates of change in temperature, precipitation, runoff, and local sea level rise rates by 2100. Sea level rise will result in the degradation of groundwater quality ...

Nature, age, and origin of the informal Lower Cenozoic Red Bank group, northern Belize 

Ricketts, Sandor (2020-08-17)  ETD File Embargoed
The informal Lower Cenozoic Red Bank group of Belize crops out in several areas of the northern part of the country and is comprised mainly of clay with relatively minor amounts of carbonate and rare evaporite beds. The ...

Overpressure in the Eastern Bengal Basin, Bangladesh, and Its Relation to Compressional Tectonics 

Hossain, Muhammad (2009-08-11)
Proximity to the Indian craton, the Himalayas, and the Indo–Burman ranges and rapid orogenic sedimentation have resulted in the generation of overpressure in the Bengal basin. In eastern Bengal basin, overpressure zones ...

Paleogeographic Reconstruction of Part of Eastern Gondwanaland:Petrofacies and Detrital Geochronologic Study of Permo-Carboniferousgondwanan Sequences of India and Bangladesh 

Chowdhury, Nur Uddin Md. Khaled (2014-08-19)
This study has been carried out focusing on petrofacies and geochronology of Permo-Carboniferous Gondwanan sequences of Barapukuria, Dighipara, and Khalaspir coal basins in the Bengal Basin and Jharia Basin in the Eastern ...

Petrofacies Analysis and Detrital Geochronology of Oligocene Sediments from the Bengal Basin and Southeast Shillong, Northeast India 

Naher, Jasmin (2020-09-09)  ETD File Embargoed
Oligocene sedimentation at the Assam-Bengal system provides a record of shifting sediment source areas and unroofing events in the adjacent Himalayan mountain and accretionary wedges of Indo-Burman ranges during the early ...

Petrofacies and Detrital Geochronology of the Lower Pennsylvanian Pottsville Formation from the Northern Appalachian Basin, Pennsylvania 

Monami, Shifat (2019-07-30)  ETD File Embargoed
The Appalachian foreland basin preserves a late Paleozoic synorogenic clastic wedge formed during the Alleghenian orogeny in response to the collision between Laurentian and Gondwanan continents. The Lower Pennsylvanian ...
