Abstract Because of their extreme heterogeneity at multiple scales, carbonate rocks present a great challenge for studying and managing oil reservoirs. Depositional processes diagenetic alterations carbonates may have produced very complex pore structures and, consequently, variable fluid storage flow properties hydrocarbon To understand the impact mineralogy on system, we analyzed four rock sa...

Introduction: The Miniature Thermal Emission Spectrometer (Mini-TES) instrument aboard the Mars Exploration Rover Opportunity has been used to acquire thousands of spectra from the surface of Merid-iani Planum [1]. The Mini-TES measures thermal in-frared energy at a similar spectral resolution and range to that of the Thermal Emission Spectrometer (TES) aboard the Mars Global Surveyor orbiting ...

[1] The main objective of the present study is to discuss in detail the results obtained from an inversion of the Apollo lunar seismic data set, lunar mass, and moment of inertia. We inverted directly for lunar chemical composition and temperature using the model system CaO-FeO-MgO-Al2O3-SiO2. Using Gibbs free energy minimization, stable mineral phases at the temperatures and pressures of inter...

We present visible and near-infrared reflectance spectra and interpreted surface mineralogy for asteroid 10537 (1991 RY16). The spectrum of this object is without precedent amongst the Main Belt asteroids. A unique absorption band centered at 0.63 microns could be attributed to one of several mineralogies. Pronounced 1and 2-micron absorption bands suggest that the composition of 10537

The overall purpose of the project was to explore and quantify the processes that control the formation and reactivity of biogenic iron microminerals and their impact on the solubility of metal contaminants. The research addressed how surface components of bacterial cells, extracellular organic material, and the aqueous geochemistry of the DIRB microenvironment impacts the mineralogy, chemical ...
