Raman spectroscopy of irradiated organic matter (2007)
Court, Richard, Sephton, Mark, Parnell, J., Gilmour, Iain
Raman spectroscopy of a range of irradiated and nonirradiated natural terrestrial bitumens has revealed that radiolytic alteration is generally associated with an increase in structural...
Wilson, Rebecca, Pearson, Victoria, Morgan, Geraint, Franchi, Ian, Turner, D. C., Wright, Ian, ...
We present the results of a new simulation of the atmospheric entry heating experienced by extraterrestrial dust particles, quantifying their volatile loss into the early Earth atmosphere and...
Watson, Jonathon S., Sephton, Mark A., Sephton, Sarah V., Self, Stephen, Fraser, Wesley T., Lomax, Barry H., ...
Spore chemistry is at the centre of investigations aimed at producing a proxy record of harmful ultraviolet radiation (UV-B) through time. A biochemical proxy is essential owing to an absence of...
Application of GCxGC-ToFMS in the analysis of meteoritic organic macromolecules (2007)
Watson, Jonathan, Turner, Diane, Gilmour, Iain, Sephton, Mark, Morgan, Geraint
Pearson, Victoria, Sephton, M.A., Franchi, Ian, Gibson, Jennifer, Gilmour, Iain
We have undertaken a comprehensive study of carbon and nitrogen elemental abundances and isotopic compositions of bulk carbonaceous chondrites. A strategy of multiple analyses has enabled the...
Molecular and isotopic indicators of alteration in CR chondrites (2006)
Pearson, Victoria K., Sephton, M., Gilmour, Iain
The CR group of carbonaceous chondrites may represent some of the most primitive extraterrestrial materials available for analysis. However, in contrast to other chondrite groups, the CR organic...
Oxygen-containing aromatic compounds in a Late Permian sediment (2005)
Watson, Jonathan S., Sephton, Mark A., Looy, Cindy V., Gilmour, Iain
In northern Italy the base of the Tesero Oolite Horizon represents the lithological boundary between the Bellerophon and Werfen Formations and marks one of the most dramatic environmental...
Free and bound carboxylic acids in carbonaceous chondrites (2005)
Watson, Jonathan, Martins, Zita, Botta, Oliver, Ehrenfreund, Pascale, Gilmour, Iain, Sephton, Mark
Spore chemistry as a proxy for UV-B flux (2005)
Watson, Jonathan, Sephton, Mark, Sephton, Sarah, Beerling, David, Self, Stephen, Gilmour, Iain, ...
Watson, Jonathan S., Pearson, Victoria K., Sephton, Mark A., Gilmour, Iain
Organic materials isolated from carbonaceous meteorites provide us with a record of pre-biotic chemistry in the early Solar System. Molecular, isotopic and in situ studies of these materials suggest...
An Introduction to the Solar System / Ed. de N. McBride, I. Gilmour. (2004)
McBride, Neil (ed.), Gilmour, Iain (ed.)
Contenido: 1) Un viaje a Sistema Solar; 2) La estructura interna de los planetas terrestres; 3) Vulcanismo planetario, ultima Thule; 4) Proceso en la superficie planetaria; 5) Atmósferas de los...
Contamination by sesquiterpenoid derivatives in the Orgueil carbonaceous chondrite (2003)
Watson, Jonathan S., Pearson, Victoria K., Gilmour, Iain, Sephton, Mark A.
The free organic components of the Orgueil carbonaceous chondrite have been the subject of much controversy. Several proposals for their source have been put forward including extraterrestrial...
Gilmour, Iain, Sephton, M. A., Morgan, J. V.
The organic geochemistry of hydrocarbon-rich core material recovered by the CSDP is examined to establish whether hydrocarbons are associated with the migration and emplacement of organic matter by...
Hydropyrolysis of insoluble carbonaceous matter in the Murchison meteorite (2003)
Sephton, Mark, Love, Gordon, Watson, Jonathan, Verchovsky, Sasha, Wright, Ian, Snape, Colin, ...
Clay mineral-organic matter relationships in the early solar system (2002)
Pearson, Victoria K., Sephton, Mark A., Kearsley, Anton T., Bland, Philip A., Franchi, Ian A., Gilmour, Iain
As the solar system formed, it inherited and perpetuated a rich organic chemistry, the molecular products of which are preserved in ancient extraterrestrial objects such as carbonaceous chondrites....
Koeberl, Christian, Gilmour, Iain, Reimold, Wolf Uwe, Claeys, Philippe, Ivanov, Boris
Kaiho et al. report sulfur isotope and chemical data for samples from the Meishan (China) Permo-Triassic (P-Tr) boundary section. They interpret the S-isotope data, as well as the occurrence of Fe-...
Sulfur isotopic compositions across terrestrial Cretaceous-Tertiary boundary successions (2002)
Maruoka, Teruyuki, Koeberl, Christian, Newton, Jason, Gilmour, Iain, Bohor, Bruce F.
About the book: This volume contains the proceedings of the fourth of an informal series of meetings on mass extinctions, global catastrophes, and the geological and biological consequences of...
