The Prebiotic Provenance of Semi-Aqueous Solvents
Autor: Rio Febrian, Matthew A. Pasek, Bradley T. Burcar, Jennifer Lago, Christopher A. Mehta, Nicholas V. Hud, Z. D. Atlas, Paul J. Bracher
Publikováno v: Origins of Life and Evolution of Biospheres. 50:1-14
The numerous and varied roles of phosphorylated organic molecules in biochemistry suggest they may have been important to the origin of life. The prominence of phosphorylated molecules presents a conundrum given that phosphorylation is a thermodynami

Insights on the process of two-stage coronae formation at olivine-plagioclase contact in mafic dyke from Palghat Cauvery Shear Zone, southern India
Autor: Upama Dutta, R. Anand, Z. D. Atlas, Meenakshi Banerjee
Publikováno v: Mineralogy and Petrology. 113:625-649
Coronae between olivine and plagioclase are a common replacement texture in mafic rocks by magmatic and metamorphic processes. Mafic dykes from Palghat Cauvery Shear Zone (PCSZ) of the granulite terrane of southern India display such multilayer coron

Crystallization and Segregation of Syenite in Shallow Mafic Sills: Insights from the San Rafael Subvolcanic Field, Utah
Autor: Danielle Koebli, M. Diez, Aurélie Germa, Z. D. Atlas, Ivan P. Savov, Elisabeth Gallant, Paul H. Wetmore, Vanessa Greaves, Austin Arias
Publikováno v: Journal of Petrology. 61
Exposed plumbing systems provide important insight into crystallization and differentiation in shallow sills beneath volcanic fields. We use whole rock major element, trace element and radiogenic isotopic compositions, along with mineral geochemical

Evaluation of digestion methods for analysis of trace metals in mammalian tissues and NIST 1577c
Autor: Rainer Metcalf, Kenyon G. Daniel, Z. D. Atlas, Grace A. Binder
Publikováno v: Analytical Biochemistry. 543:37-42
Digestion techniques for ICP analysis have been poorly studied for biological samples. This report describes an optimized method for analysis of trace metals that can be used across a variety of sample types. Digestion methods were tested and optimiz

Stratigraphy, sedimentology and inferred flow dynamics from the July 2015 block-and-ash flow deposits at Volcán de Colima, Mexico
Autor: Nick Varley, E. Macorps, Lucia Capra, Z. D. Atlas, Sylvain J. Charbonnier, Josep Cabré
Publikováno v: Journal of Volcanology and Geothermal Research. 349:99-116
The July 2015 block-and-ash flow (BAF) events represent the first documented series of large-volume and long-runout BAFs generated from sustained dome collapses at Volcan de Colima. This eruption is particularly exceptional at this volcano due to (1)

Contrasting sediment melt and fluid signatures for magma components in the Aeolian Arc: Implications for numerical modeling of subduction systems
Autor: Jeffrey G. Ryan, C. Cannatelli, Sarah E. Mazza, Z. D. Atlas, Federico Lucchi, Benedetto De Vivo, Denis Zamboni, Esteban Gazel, Jarek Trela
Publikováno v: Geochemistry, Geophysics, Geosystems. 17:2034-2053
The complex geodynamic evolution of Aeolian Arc in the southern Tyrrhenian Sea resulted in melts with some of the most pronounced along the arc geochemical variation in incompatible trace elements and radiogenic isotopes worldwide, likely reflecting

Archean phosphorus liberation induced by iron redox geochemistry
Autor: Ruth E. Blake, Sae Jung Chang, Barry Herschy, Heather Abbott-Lyon, Aivo Lepland, Terence P. Kee, Jacqueline M. Sampson, Matthew A. Pasek, Z. D. Atlas
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-7 (2018)
Nature Communications
The element phosphorus (P) is central to ecosystem growth and is proposed to be a limiting nutrient for life. The Archean ocean may have been strongly phosphorus-limited due to the selective binding of phosphate to iron oxyhydroxide. Here we report a

Redox chemistry in the phosphorus biogeochemical cycle
Autor: Jacqueline M. Sampson, Z. D. Atlas, Matthew A. Pasek
Publikováno v: Proceedings of the National Academy of Sciences. 111:15468-15473
The element phosphorus (P) controls growth in many ecosystems as the limiting nutrient, where it is broadly considered to reside as pentavalent P in phosphate minerals and organic esters. Exceptions to pentavalent P include phosphine--PH3--a trace at
