Catastrophes were common in the geologic past, but their distinction from other events is necessary. Besides magnitude (strength), scales of events are important in a solution of this task. Several examples, which involve Late Paleozoic and Quaternary megafloods, Hadean and Phanerozoic extraterrestrial impacts, and Phanerozoic mass extinctions, ensure that scaling by spatial extent and diversity of consequences facilitates tracing the boundary between catastrophes and “ordinary” events. This boundary, however, is dynamic and its position depends on our subjective needs. Considerations of the geologic past should not mix catastrophes of different scales. The event analysis helps to avoid such a pitfall, and, therefore, it should be  preferred to neocatastrophism in modern geoscience.

Tashtagol administrative district of the Kemerovo region is located in its southern part occupying the up-streams of the Mras-su and the Kondoma rivers. Deposits of the Late Precambrian (Vendian) and the Paleozoic (Early Cambrian), which are relics of oceanic carbonate platform, youthful and mature island arc, form geological structure of the territory. The sequence is broken through by intrusive bodies, of which plagiogranite intrusions of the Late Cambrian (skarn deposits of iron ore) are of the greatest impact for metallogeny of the region. Analysis of regional mineral resources begins with a survey of reserves and resources of ferrous metals (iron, manganese), then resource potential for noble metals and non-metallic minerals is considered consistently. Iron has historically been the main mineral resource of the region, but as of the present, prospects remain only for the Tashtagolskoye deposit. The gold placers has practically been exhausted, development of the Selezenskoye manganese deposit has been stopped due to complexity of its geological structure. Other diverse deposits of metallic and nonmetallic minerals are practically not explored, framing reserves for the future.
