***************************************************** From: Stephane Polteau <polteau@xxxxxxxxxx> ***************************************************** Dear all, I would like to draw your attention to the session described below for the next AGU fall meeting in San Francisco the 10-14th December 2007. Please remember submitting your abstract(s) before the 6 September 2007 deadline from: http://submissions3.agu.org/submission/entrance.asp sorry for multiple postings Sincerely Stephane Polteau V14: Saucer-Shaped Sills, Injected Sands and Related Structures: Formation Mechanisms, Examples, and Extra-Terrestrial Analogues Abstract: Magma and fluidized sand can develop bowl- or saucer-shaped structures that are increasingly recognized by field observations and by detailed seismic imaging in petroleum provinces (Nevada, California, Greenland, Siberia, Svalbard, South Africa, Norwegian and North Sea Basins). The intrusions can affect organic matter maturation, oil migration pathways, the plumbing systems of hydrocarbon reservoirs, and they may also form aquifers. The aim of this session is to investigate the origin of saucer-shaped intrusions and genetically related structures in terms of properties of the crust and injected liquid, water and volatile contents, and depth of emplacement of individual intrusions. We invite contributions on saucer-shaped intrusions, either magmatic or fluidized sand in origin, with their associated settings, deformation, peripheral structures and physical processes controlling their final geometry. Contributions on potential extra-terrestrial analogues are welcome.
