AbstractAbout the AuthorReferences
A geostatistical predictive and prospecting model of gold mineralization (map of potential resource prospects) for the area of the Central Kolyma region (within the Inyali-Debinsky synclinorium) was built using machine learning methods.
Multispectral satellite images, materials of medium- and small-scale geological mapping, data of medium-scale geophysical and lithochemical surveys were used as source data. Based on this data, an exhaustive set of indicators related to the search criteria was calculated. To build a forecast, the Random Forest method was used using random negative samples and averaging the result. The obtained forecast maps allow localizing potential gold ore objects with a spatial resolution of 2 km, which makes it possible to select promising areas for licensing. In addition, the possibilities of using machine learning methods for metallogenic zoning of the territory are shown.
