Abstract

The data on the Precambrian metallogeny of India are integrated in order to provide insights into its basic principles and to create a digital cartographic representation of the results obtained. The description of an electronic map of the Precambrian of India on a scale of 1: 5000000 is an example of the creation of a GIS-oriented database on the geology and tectonics, isotopic age, and minerageny of the Precambrian rocks of continents. Precambrian geological and tectonic bodies are individualized as the main ore-bearing structural elements assigned for typification, systematics, ranking, classification, correlation, and demarcation of territories differing in geological features. The metallogenic information on Precambrian provinces of India is considered at three formalized levels: metallogenic provinces, zones, and mineral deposits located in typical structural elements. Each object is accompanied by a spatiotemporal model of tectonic and metallogenic evolution characterized by isotopic dating with various degrees of accuracy.
