EPSL: Sulfur isotopic compositions of deep arc cumulates

Sulfur isotopic compositions of deep arc cumulates Cin-Ty A. Lee, Monica Erdman, Wenbo Yang, Lynn Ingram, Emily J. Chin, Donald J. DePaolo Earth and Planetary Science Letters, Volume 500, 15 October 2018, Pages 76-85 https://doi.org/10.1016/j.epsl.2018.08.017 Heavy sulfur isotopic compositions of arc lavas suggest a seawater component in the sulfur budget of arc lavas, but whether […]

ChemGeol: Trace elements and U-Pb ages in petrified wood as indicators of paleo-hydrologic events

Trace elements and U-Pb ages in petrified wood as indicators of paleo-hydrologic events Hehe Jiang, Cin-Ty Lee, William G.Parker Chemical Geology, Volume 493, 20 August 2018, Pages 266-280 https://doi.org/10.1016/j.chemgeo.2018.06.002 Subsurface fluid systems are important for chemical weathering, ore formation and thermal evolution of the crust. Changes in the dynamics and distribution of subsurface fluid flow […]

Science Advances: The redox “filter” beneath magmatic orogens and the formation of continental crust

The redox “filter” beneath magmatic orogens and the formation of continental crust Ming Tang, Monica Erdman, Graham Eldridge and Cin-Ty A. Lee Science Advances 2018: Vol. 4, no. 5, eaar4444, DOI: 10.1126/sciadv.aar4444 The two most important magmatic differentiation series on Earth are the Fe-enriching tholeiitic series, which dominates the oceanic crust and island arcs, and […]

Scientific Reports: Volcanic ash as a driver of enhanced organic carbon burial in the Cretaceous

Volcanic ash as a driver of enhanced organic carbon burial in the Cretaceous Cin-Ty Lee, Hehe Jiang, Elli Ronay, Daniel Minisini, Jackson Stiles, Matt Neal Scientific Reportsvolume 8, Article number: 4197 (2018) doi:10.1038/s41598-018-22576-3 On greater than million year timescales, carbon in the ocean-atmosphere-biosphere system is controlled by geologic inputs of CO2 through volcanic and metamorphic degassing. High atmospheric […]

EPSL: An imbalance in the deep water cycle at subduction zones: The potential importance of the fore-arc mantle

An imbalance in the deep water cycle at subduction zones: The potential importance of the fore-arc mantle Julia Ribeiro and Cin-Ty Lee Earth and Planetary Science Letters Volume 479, 1 December 2017, Pages 298-309 The depth of slab dehydration is thought to be controlled by the thermal state of the downgoing slab: cold slabs are […]

IRESS 2018 – Hoeink

The Quest for Permeability Tobias Hoeink Baker Hughes, a GE company   The only economical way to extract hydrocarbons from low-permeability shale reservoirs is to increase reservoir contact. Horizontal drilling, multi-stage completion, and hydraulic fracturing have proven key technologies in this respect. Yet, there is more to consider when engineering for optimal recovery on the […]

IRESS 2018 – Torres

The life and times of carbon in surface environments Mark Torres, Rice University The geologic cycling of carbon is multifaceted and key to Earth’s long-term habitability. Central to many aspects of the C cycle is the physical transport of terrestrial materials to the ocean and the biogeochemical transformations that occur during transport. Here, we use […]

IRESS 2018 – Minisini

Carbon Cycling, from Volcanoes to Source Rocks, a sedimentary perspective Daniel Minisini, Shell The deep Earth processes (e.g., tectonism, magmatism, volcanism) control the first order shape of the continental margins, the surface Earth processes (e.g., climate, erosion, sediment supply) reshape them through the redistribution of sediment. The interaction between the deep and the surface Earth […]

IRESS 2018-Reinhard

The importance of nutrients for Earth’s carbon cycle Chris Reinhard, Georgia Institute of Technology The global carbon cycle links together the biosphere, planetary climate, and the chemistry of the oceans and atmosphere. The cycling of carbon at Earth’s surface is in turn governed by feedbacks linking it with the oxygen and sulfur cycles, the cycling […]

IRESS 2018-Madof

Gas hydrates in sandy reservoirs interpreted from velocity pull up: Are Mississippi-fan turbidites diffusively charged? Andrew Madof, Chevron   Gas hydrates are recognized as an emerging energy resource and submarine geohazard; they are also thought to be a modulating mechanism on the global organic carbon budget and on past climate change. Although identified primarily from […]
