Djerfisherite: Nebular Source of Refractory Potassium
Denton S. Ebel, Richard O. Sack
Djerfisherite is an important carrier of potassium in highly reduced enstatite chondrites, where it occurs in sub-round metal-sulfide nodules. These nodules were once free-floating…
Laser Scanning Confocal Microscopy of Comet Material in Aerogel
Michael Greenberg, Denton S. Ebel
We report non-destructive 3-dimensional imaging and analysis techniques for material returned by the Stardust cometary collector. Our technique utilizes 3-dimensional laser scannin…
Equilibrium Condensation from Chondritic Porous IDP Enriched Vapor: Implications for Mercury and Enstatite Chondrite Origins
Denton S. Ebel, Conel M. O'D. Alexander
The origin of Mercury's anomalous core and low FeO surface mineralogy are outstanding questions in planetary science. Mercury's composition may result from cosmochemical controls o…
The Origin of Chondrules: Constraints from Matrix-Chondrule Complementarity
Herbert Palme, Dominik C. Hezel, Denton S. Ebel
One of the major unresolved problems in cosmochemistry is the origin of chondrules, once molten, spherical silicate droplets with diameters of 0.2 to 2 mm. Chondrules are an essent…
Experimental Investigation of Condensation Predictions for Dust-Enriched Systems
Gokce Ustunisik, Denton S. Ebel, David Walker +1
Condensation models describe the equilibrium distribution of elements between coexisting mineral solid solutions, silicate liquid, and vapor in a closed chemical system, vapor phas…
Condensation in Dust-Enriched Systems
Denton S. Ebel, Lawrence Grossman
Full chemical equilibrium calculations of the sequence of condensation of the elements from cosmic gases made by total vaporization of dust-enriched systems were performed to inves…
