Several technical challenges are related to data collection, inverse modeling, model fusion, and integrated interpretations in the exploration of geophysics. A fundamental problem geophysical interpretation is proper geological understanding multiple inverted physical property images. Tackling this requires high-dimensional techniques for extracting information from modeled In study, we develop...

singularity based on fractal and multifractal is a technique for detection of depletion and enrichment for geochemical exploration, while the index of vertical geochemical zonality (vz) of pb.zn/cu.ag is a practical method for exploration of blind porphyry copper mineralization. in this study, these methods are combined for recognition, delineation, and enrichment of vz in jebal- barez in the s...

The history of the mining industry is intimately connected with government regulation. As in many other countries, this reflects the fact that the Crown has reserved almost all mineral rights to itself. In many cases regulation has had adverse consequences for the sector. A notorious example was the ban on exports of iron ore in the 1960s, which depressed exploration activity and postponed the ...

Geochemical studies and surveys conducted by the Geological Survey of Canada have provided considerable information about the natural geochemical variations in glacial drift, lake sediments, and lake waters in south-central District of Keewatin. In addition to their intended contribution to mineral exploration, these activities yielded much basic background data that may be applied to the plann...

Airborne geophysical systems have been in use since 1943 (Hildenbrand et al., 1990). These systems used airborne magnetometers for submarine detection and geophysical mapping. Airborne electromagnetic systems were introduced in the 1950s (Barringer et al., 1990) for mineral exploration. These early magnetic and electromagnetic systems were mounted on fixed wing aircraft. In the 1960s helicopter...

In this paper we describe a learning technique for reactive path-planning and guidance of autonomous robots using a Kohonen self-organizing neural network. The intended application is mineral exploration or agricultural monitoring using simple lowcost robots which do not contain a complete stored map of the environment, and may have unreliable sensor information. The network learns based on a s...
