Geological mapping in vegetation coverage areas is a challenging task. In this study, convolutional neural networks (CNNs) were employed for geological area based on remote sensing images and geochemical survey data. The Gram-Schmidt fusion technology was first applied to fuse Sentinel-2A ASTER enhance the spatial resolution enrich spectral information of fused then organically integrated with ...

Antecedent topography such as relic reef terraces well biogenic carbonate relief-forming deposits ~30–150 m deep, referred to mesophotic reefs, provide structural support for diverse coral ecosystems (MCEs) that may serve refuges select light-dependent species. Although at depths are found globally, an understanding of their spatial distribution, formation, and relationship with living communit...

Pantropical variation in soils of the tropical dry forest (TDF) biome is enormously high but has been poorly characterized. To quantify global distribution TDF soil physical and chemical properties relation to climate geology, we produced a synthesis using 7500 points data with gridded fields representing lithologic, edaphic, climatic characteristics. Our analyses reveal that 75 ecoregions acro...

INTRODUCTION Precambrian rocks in the Tusas Mountains range from nearly monomineralic quartzite, in which the principal result of metamorphism has been simple recrystallization, through locally metasomatized schist and gneiss profoundly modified by potash-rich fluids during the intrusion of pegmatite. Texturally, the rocks range from schist and phyllite containing penetrative and pervasive clea...

| 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...
