[1] We estimate crustal structure and thickness of South America north of roughly 40°S. To this end, we analyzed receiver functions from 20 relatively new temporary broadband seismic stations deployed across eastern Brazil. In the analysis we include teleseismic and some regional events, particularly for stations that recorded few suitable earthquakes. We first estimate crustal thickness and av...

This paper introduces the results of integration of lexical and terminological resources, most of them developed within the Human Language Technology (HLT) Group at the University of Belgrade, with the Geological information system of Serbia (GeolISS) developed at the Faculty of Mining and Geology and funded by the Ministry of the Environmental protection. The approach to GeolISS development, w...

Global geologic maps are useful tools for efficient interpretation of a planetary body, and they provide global context the diversity evolution surface. We used data acquired by OSIRIS-REx spacecraft to create first map near-Earth asteroid (101955) Bennu. As this is small, non-spherical, rubble-pile asteroid, we discuss distinctive mapping challenges best practices that may be future exploratio...

Geologic maps are foundational products for natural hazard assessments but developing them submarine areas is challenging due to a lack of physical access the study area. In response, geomorphologic used provide geologic context and spatial information on landforms related geo-hazards risk management. These generated from remotely sensed data, e.g. digital elevation models (DEMs), which introdu...

Background: The Mars Express and Mars Reconnaissance Orbiter spacecraft both carry radar sounder systems (MARSIS and SHARAD). These instruments transmit a radar signal with wavelength of meters to tens of meters, and penetrate to depths of several km in typical dry crustal rocks. Sounders, however, provide relatively coarse horizontal resolution (1-10 km), and cannot reveal detail of the near-s...

Processes of terrestrial geologic mapping and preparation of geologic maps are supported by Geographic Information Systems (GIS) and respective datamodels of which an assessable number are currently available. Such datamodels help mappers to define spatial geologic map units by integrating field and remote-sensing information and relate them to non-spatial information about unit details, in par...

gamma-rays emitted from the ground surface relate to the primary mineralogy and geochemistryof the bedrock, and the secondary weathered materials. this information can contribute significantly to anunderstanding of the geochemical and pedogenetic history of a region. the main aim of this paper was to study the relationship between ground gamma-ray data and basement geochemistry in the lese catc...

An image processing technique called the cellular neural network (CNN) approach is used in this study to locate geological features giving rise to gravity anomalies such as faults or the boundary of two geologic zones. CNN is a stochastic image processing technique based on template optimization using the neighborhood relationships of cells. These cells can be characterized by a functional bloc...
