oa Innovative approaches to information modeling of placer deposits

The paper is devoted to the problem of information support for geological research and works aimed at developing the mineral resources base of priority sectors of the national industry The purpose of this publication is to present innovative approaches to information modeling of placer deposits of heavy minerals, cassiterite and rare-metal mineralization, amber. The tasks are the coverage of the methodology and methods, demonstration of modeling examples for typical objects, designation of a strategy for further research in the field of information modeling. The methodological basis of targeted information modeling is the formation analysis combined with the approaches of info-geology. Methodological and methodic development is predictive and reconstructive complex for modeling geological objects of various scales. The methodological complex of information support for research and works includes two blocks: a predictive-paleoreconstructive retrospective-static model and an integrated ecological-geological model of a local geological object (CEGM), including a digital structural-lithological (subordinate rank) model (DSLM) and other functional submodels. The examples of modelling of placers are shown. Prospects for the further development of information modeling are suggested.
