Mineralogical and geochemical data

From these mineralogical and geochemical data we may reconstruct the formations of the Upper Silurian as potential source rocks for hydrocarbons. The widespread presence of large proportions of iUitic-kaolinitic clay minerals indicates that the Silurian sedimentation took place under relative tectonic stability and that the supply of the clastic material came from a peneplaned region with humid climate resulting in a weathering zone of illito-kaolinitic composition. 

The present review will focus on the synthetic and structural studies as well as on applications. The mineralogical and geochemical aspects of the rare earth silicates are only briefly summarized as there is a comprehensive review in English on the silicate minerals (Gmelin, 1984b). The structural chemistry of the sihcates has also been reviewed earlier but a lot of new data have accumulated since the appearance of the authorative review by Felsche (1973).

Forward geochemical modeling. Given an initial water of known composition and a rock of known mineralogy and composition, the rock and water are computationally reacted under a given set of conditions (constant or variable temperature, pressure, and water composition) to produce rock and water (or set of rocks and waters). In forward modeling the products are inferred from an assumed set of conditions (equilibrium or not, phases allowed to precipitate or not, etc.) and thermodynamic and/or kinetic data are necessary.

A 40-km x 40 km sample spacing for the North American project will provide soil geochemical and mineralogical data that will display coherent and robust regional to continental-scale patterns, as also demonstrated by Smith and Reimann (2008).
