| We consider the problem of characterizing the lithology of a reservoir using gamma ray logs as well as seismic traces around the well. We rst calculate the continuous wavelet transform of the the data and then use the fact that the energy of such transformation is proportional to a power of its scale. The technique consists in estimating the power transformation obtaining a set of values of t...

Seismic imaging, popularly known as tomography, borrowing the term from medical sciences, produces the raster image of the internal structure by combining information from a set of projections obtained at different viewing angles. To engineer high resolution and accurate solutions to mining problems, seismic traveltime tomography can yield a high resolution image of the subsurface to provide in...

Introduction: Since January 2004, OMEGA/Mars Express data has revealed a diverse and complex Martian surface mineralogy [1]. The important findings, together with Thermal Emission Spectrometer (TES), Thermal Emission Imaging System (THEMIS), and insitu observations from Mars Exploration Rovers, include but not limited to (1) hydrated sulfates [1, 2, 3, 4, 5, 6, 7]; (2) iron oxides and oxhydroxi...

Abstract Weathering of silicate rocks at a planetary surface can draw down CO 2 from the atmosphere for eventual burial and long-term storage in interior. This process is thought to provide essential negative feedback carbonate-silicate cycle (carbon cycle) maintain clement climates on Earth potentially similar temperate exoplanets. We implement thermodynamics determine weathering rates as func...

Detection and verification of underground nuclear explosions (UNEs) can be improved with a better understanding the nature extent explosion-induced damage in rock effect this on radionuclide migration. Much previous work area has focused centimeter- to meter-scale manifestations damage, but predict permeability for migration, observations at smaller scales are needed determine deformation mecha...

Seismic correlation of glacial unconformities from the Ross Sea outer continental shelf to chronostratigraphic control at DSDP sites 272 and 273 indicates that at least two West Antarctic Ice Sheet (WAIS) expansions occurred during the early part of the middle Miocene (i.e. well before completion of continental-scale expansion of the East Antarctic Ice Sheet (EAIS) inferred from N18O and eustat...
