Determining timescales of natural carbonation of peridotite in the Samail Ophiolite, Sultanate of Oman
(Massachusetts Institute of Technology, 2012)
Determining timescales of the formation and preservation of carbonate alteration products in mantle peridotite is important in order to better understand the role of this potentially important sink in the global carbon ...
Trace element proxies and mineral indicators of hydrothermal fluid composition and seafloor massive sulfide deposit formation processes
(Massachusetts Institute of Technology, 2017)
This thesis analyzes compositions of seafloor massive sulfide (SMS) deposits and related hydrothermal vent fluids to identify proxies of reaction zone conditions (host-rock lithology, hydrothermal fluid temperature and ...
The CAFE experiment : a joint seismic and MT investigation of the Cascadia subduction system
(Massachusetts Institute of Technology, 2013)
In this thesis we present results from inversion of data using dense arrays of collocated seismic and magnetotelluric stations located in the Cascadia subduction zone region of central Washington. In the migrated seismic ...
Chemical, isotopic, and temporal variations during crustal differentiation : insights from the Dariv Igneous Complex, Western Mongolia
(Massachusetts Institute of Technology, 2016)
Fractional crystallization of mantle-derived basaltic melts is a critical process in producing a compositionally stratified continental crust characterized by a silicic upper crust and a mafic lower crust. This thesis ...
Climate controls on coral growth in the Caribbean
(Massachusetts Institute of Technology, 2013)
Accurate predictions of Caribbean coral reef responses to global climate change are currently limited by a lack of knowledge of the dominant environmental controls on coral growth. Corals exhibit significant responses to ...
Quaternary morphology and paleoenvironmental records of carbonate islands
(Massachusetts Institute of Technology, 2014)
Here I use a simple numerical model of reef profile evolution to show that the present-day morphology of carbonate islands has developed largely in response to late Pleistocene sea level oscillations in addition to variable ...
