The present study deals with the estimation of the advanced spaceborne thermal emission and reflection radiometer (ASTER) data for geological application. Visible, near-infrared and short wave infrared reflectance data (9 ASTER bands) have been processed and interpreted in framework of a mapping project concerning the western margin of the Kalahari desert. A methodology has been applied to appa...

Active inference offers a first principle account of sentient behavior, from which special and important cases—for example, reinforcement learning, active Bayes optimal inference, design—can be derived. finesses the exploitation-exploration dilemma in relation to prior preferences by placing information gain on same footing as reward or value. In brief, replaces value functions with functionals...

Because of atmospheric shielding and endogenic resurfacing, the population of impact craters on Venus is small (about a thousand) and consists of large craters. This population has been used in numerous studies with the goal of deciphering the geologic and geodynamic history of Venus, but the nearly spatially random nature of the crater population has complicated efforts to understand this hist...

With the continued growth in demand for mineral resources and China's efforts in increasing investment in geological prospecting, fiscal investment in geological exploration becomes a research hotspot. This paper examines the yearly relationship among fiscal investment in geological exploration of the current term, that of the last term and prices of mining rights over the period 1999-2009. Hin...

truncated gaussian simulation (tgs) is a well-known method to generate realizations of the ore domains located in a spatial sequence. in geostatistical framework geological domains are normally utilized for stationary assumption. the ability to measure the uncertainty in the exact locations of the boundaries among different geological units is a common challenge for practitioners. as a simple a...

AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area floristic divisions in Amazonia. Here we ask whether Amazonian forests are partitioned into broad-scale floristic units on the basis of geological formations a...

This study investigates the E-mineral rights trade market in China. This market could improve information disclosure, transparency and efficiency of mineral rights. In China, all mineral resources belong to the country, so this Electronic trade market is both E-business and E-government. Their subjects include departments of land and resources administration, government departments, State-owned...
