Summary of Clastic Diagenesis Research Group Meeting
AAPG Annual Meeting, San Antonio, April 21, 2008

Presentations by:

Jim Boles: The quartz-mica problem --- beyond roseite

Rob Lander: Why does quartz grow more slowly on chert compared to monocrystalline quartz grains?

Peigui Yin: Fracture diagenesis and its effects on reservoir permeability in Tensleep Sandstones, Wyoming

Peter Eichhubl: Effect of mechanical grain size reduction on quartz cementation in sandstone

Robert Reed: Nanopores and more: SEM Imaging of Ion-Beam-Milled Mudrocks

Anthony Park: Calcite cementation in sandstone, Balance.CM simulations of GOM samples: pH is only a (big) part of the story

Knut Bjørlykke: Constraints on diagenetic reactions and prediction of reservoir quality

Richard Worden: Transient-pulse decay permeability analysis and QEMSCAN mineralogy analysis of Carboniferous sandstone caprocks from Algeria

The Clastic Diagenesis challenge (a bottle of California wine this year)  went to Steve Becker at UT Austin for providing “unambiguous evidence for co-precipitation (i.e. precipitation at the same time in the same pore fluid environment) of quartz and carbonate under diagenetic conditions”.  At least he got close enough to win the vote.

Calum Macaulay offered to provide some updated content for the website.
