Arc-WofE: a GIS tool for statistical integration of mineral exploration datasets

چکیده
Mineral exploration companies increasingly are using GIS technology to combine spatial data and make predictive mineral potential maps. Weights-of-evidence is a discrete multivariate method first applied to this problem by us about 12 years ago (Bonham-Carter et al., 1988). It is easily implemented within a GIS computing environment. Arc-WofE is a new user-friendly computer code for weights-of-evidence in Avenue, developed as an “extension” to the popular Arcview GIS viewing package. In this paper we summarize the method, and present a new approach for modelling the effect of kriging error on the analysis. In the interest of brevity, only some key references are cited here (e.g. Agterberg et al., 1990; Bonham-Carter, 1994). The recent paper by Agterberg and Bonham-Carter (1999) provides a more up-to-date and complete list.

GIS modelling for Au-Pb-Zn potential mapping in Torud-Chah Shirin area-Iran
One of the major strengths of a Geographic Information System (GIS) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. These capabilities make GIS an extremely useful tool for mineral exploration. Several spatial modeling techniques can be employed to produce potential maps. However, these...

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 purpose of mineral exploration is to find ore deposits. The main aim of this work is to use the fuzzy inference system to integrate the exploration layers including the geological, remote sensing, geochemical, and magnetic data. The studied area was the porphyry copper deposit of the Kahang area in the preliminary stage of exploration. Overlaying of rock units and tectonic layers were used ...

Motivated by the recent successful results of using GIS modeling in a variety of problems related to the geosciences, some knowledge-based methods were applied to a regional scale mapping of the mineral potential, special for Cu-Au mineralization in the Feyz-Abad area located in the NE of Iran. Mineral Prospectivity Mapping (MPM) is a multi-step process that ranks a promising target area for mo...
متن کاملMineral Exploration Using GIS and Processed Aster Images
The risks of developing mineral resources need to be known as accurately as possible. This process should start at the exploration stage and continue through feasibility to the development stage. Until recently, this type of analysis was carried out manually, leading to subjective judgments. Many mining companies have built up extensive exploration geological databases, which represent signific...
