Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark May 2022

Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark

Geology: Student Scholarship & Creative Works

The Northern Range, Trinidad underwent deformation due to oblique collision of Caribbean plate with northern South America, which was then followed by transform plate motion. Deformation began in the late Miocene when sedimentary protoliths were ductility deformed and metamorphosed to greenschist facies; this event and subsequent transform deformation drove exhumation of these rocks to the surface and created their high topography. This project provides constraints of the structural history of the western Northern Range where bedrock mapping and structural analyses are most complete. Initial geologic mapping of Northern Range, which continued from the 1950s,1960s, and 1990s, focused on attempting to …


Late Jurassic Dinosaurs On The Move, Gastroliths And Long-Distance Migration, Josh Malone Dec 2019

Late Jurassic Dinosaurs On The Move, Gastroliths And Long-Distance Migration, Josh Malone

Geography: Student Scholarship & Creative Works

The Jurassic Morrison Formation of the Rocky Mountain and Colorado Plateau regions is famous for its dinosaur fossils. The Morrison Formation (150-157 Ma) is comprised mostly of sandstone and mudstone that was deposited in a terrestrial deposition system that included fluvial, paludal, and lacustrine environments. Paleocurrent data indicates that Morrison sediment was transported to the north and east. Within the Morrison Formation, we find exotic pebble and cobble-size durable clasts of quartzite, chert and vein quartz weathering out of the mudstone paleosols. We interpret these exotic clasts as gastroliths, carried within the gastric mills of dinosaurs. For this study, we …


Burundi : Water Scarcity, Isabel Salas Jan 2017

Burundi : Water Scarcity, Isabel Salas

Global Public Health

Burundi is located near the African great lakes region of East Africa. This country is one of the poorest and hungriest countries throughout the world because of this they are facing multiple problems with communicable disease. These families are seeing a reduction in the amount of water available to them and based on this they are receiving water from external sources such as wells and lakes. Most of the water throughout Burundi is contaminated with Phytoplankton which increase cholera outbreaks in this area. It has also been shown that uranium impacts the water throughout the wells and lakes. Both of …


Cruising The Canal: A Methodological Approach To Assessing Trail Conditions Along The Hennepin Canal Parkway, Alyssa Clarida Feb 2016

Cruising The Canal: A Methodological Approach To Assessing Trail Conditions Along The Hennepin Canal Parkway, Alyssa Clarida

Geography: Student Scholarship & Creative Works

Trail conditions in the United States are degrading and trail systems do not receive enough funding to repair them in a timely manner. Park managers often conduct trail assessments to collect trail condition data. They use this data to make timely and judicious decisions regarding trail repairs. However, many trail assessments are time consuming, costly, and require high levels of expertise. This project creates a trail assessment methodology that can be applied to a trail with limited funds. The final methodology was efficient, succinct, accurate, and simple to conduct. It uses a problem based methodology where every instance of degradation …


Mitigation And Beautification: Placing Rain Gardens In The Keystone Neighborhood Of Rock Island, Illinois, Rosalie K. Starenko Jan 2015

Mitigation And Beautification: Placing Rain Gardens In The Keystone Neighborhood Of Rock Island, Illinois, Rosalie K. Starenko

Independent Research Projects

With new stormwater management regulations, cities are looking for strategies to reduce urban runoff, and rain gardens are one of several strategies that capture runoff and encourage infiltration and evaporation. In doing so, pollution from runoff is mitigated and combined sewer systems experience fewer overflow events. I argue as well that the implementation of rain gardens would act as a movement for neighborhood beautification. This research develops a new methodology for placing rain gardens that: 1) maximizes the aesthetic value of the gardens by favoring high-visibility locations and 2) targets locations that would best benefit from reduced stormwater runoff. The …
