Andrew Petter et al., Dept. of Geological Sciences, Jackson School of Geosciences, The University of Texas at Austin, 1 University Station, C1100, Austin, Texas 78712-0254, USA. Posted online 10 Dec. 2012; http://dx.doi.org/10.1130/B30603.1.

Siliciclastic shelf margins are depositional features constructed from sediments that were eroded from continents and transported to the edges of deep basins such as oceans. Andrew Petter and colleagues demonstrate a new and simple method for estimating the rate of sediment delivery to ancient basins using the shelf-margin strata preserved within the basins. The method is based on equations for geomorphic modeling and utilizes the rates at which the ancient shelf margins grew to fill the basins as well as the 2-D shapes and dimensions of the shelf-margin bathymetric profiles. The rate of sediment delivery to ancient basins provides a way to reconstruct paleo-environmental conditions, such as climate change and tectonic movement, in the area where the sediments were eroded and produced. This method may also be useful for predicting the presence of hydrocarbon-bearing deepwater sandstones.


Geochemical fingerprints of volcanic materials: Identification of a pumice trade route from Pompeii to Rome
Fabrizio Marra et al., Istituto Nazionale di Geofisica e Vulcanologia, Rome, Italy. Posted online 10 Dec. 2012; http://dx.doi.org/10.1130/B30709.1.

The paper presents an innovative analytical approach, based on the use of diagrams of selected trace elements, to the study of provenance of the volcanic material employed as the aggregate in ancient Roman masonry. Samples of pumice and lava from the mortars of Forum of Caesar and Forum of Trajan, employed in the concretes of these monuments, are analyzed and their compositions are compared to those of the
