Prospectivity Analysis. The aim of prospectivity analysis is to de risk exploration decision making using large geospatial datasets and the latest mineral system knowledge.

Geochemical anomaly and mineral prospectivity mapping in GIS

Iran like other developing countries relies on the use of their natural resources to support their economic devel opment. It is clear that, oil is the most important natural resources but, utilization of mineral deposits has a long antiquity in Iran. Prospectivity mapping is used to define areas favourable for mineral exploration. It can be applied in various scales from global to local scale exploration targeting. Geographical information systems GIS provide a flexible and powerful platform to apply spatial data analysis techniques as a tool for prospectivity mapping by in.

Analysis of geologic controls on mineral occurrence; Knowledge driven modeling of mineral prospectivity; Data driven modeling of mineral prospectivity.

Summary This book documents and explains, in three parts, geochemical anomaly and mineral prospectivity mapping by using a geographic information system GIS. Possible spatial scales include the. Structural analysis in mineral exploration using a Geographic Information Systems adapted stereographic projection plotting program A. Traditional analysis methods cannot mine the depth of information or make intelligent inferences.

In recent years, some re searchers have begun applying case based reasoning. Spatial data analysis as a tool for mineral prospectivity mapping presented was done using a fuzzylogic method which allows a stepwise way to transfer expert knowledge into quantitative. Extracting and synthesizing information from existing and massive amounts of geology spatial data sets is of great scientific significance and has considerable value in its applications. To make mineral exploration less expensive, more efficient, and more accurate, it is important to move beyond traditional concepts and establish a rapid, efficient, and intelligent method of predicting the.

Brown2 and T. Predictive modelling of mineral prospectivity using GIS is a valid and progressively more accepted tool for delineating reproducible mineral exploration targets. Mineral Prospectivity Mapping MPM provides a structured quantitative methodology to integrate these multiple spatial datasets to analyse the distribution of mineral deposits and model their spatial. Spatial modelling techniques, including weights of evidence, logistic regression and fuzzy logic, have been used in this study for a mineral prospectivity analysis to test the utility of these methods in a target scale gold exploration project within the.

Geoscientific data is often acquired by national and provincial geological surveys but remains under utilised due to a lack of resources or in house expertise. One way to utilise this data is to produce.

  • As the main result of this study we show that Fractal modeling in spite of the Boxplot, is not recommended for complex geological settings. The proved shallow anomalies recorded by geophysical studies and defined by the used methods are in accordance to the stringer zone of a volcanic massive sulfide VMS deposit in Mesgaran mining area which means this region is the bottom of a VMS deposit and geochemical anomalies are related to the remained parts of the deposit.
