For geological analysis tasks such as reservoir characterization and petroleum exploration, lithology identification is a crucial foundational task. The logging at this stage generally build model, assuming that the data share an independent identical distribution. This assumption, however, does not hold among various wells due to variations in depositional conditions, apparatus, etc. In additi...

GRA 95209 may provide our best opportunity to date to understand the earliest stages of core formation in asteroidal bodies. This lodranite preserves a physically, chemically, and mineralogically complex set of metal–sulfide veins. High-resolution X-ray computed tomography revealed three distinct lithologies. The dominant mixed metal–silicate–sulfide matrix is cut by metal-rich, graphite-bearin...

Introduction: We present a spectral deconvolution technique and model based on the description of electronic transition absorption bands in continuumremoved spectra. The model differs from the standard gaussian modeling in the way the continuum is removed. An improved nonlinear curve fitting algorithm is used to fit the model to the data. The approach represents also an alternative to the MGM m...
