Rescaling of fluid-conducting fault structures

Abstract

The interrelation between geometric parameters (density and length) of the fault systems of four scale levels (kilometers, meters, centimeters, and millimeters) was established for the first time by detailed structural study of the rocks of the Urtui granite massif located in the western framework of the Strel’tsovskii uranium caldera in the Southeastern Transbaikalia. The further use of these geostructural data for conceptual and numerical modeling of the fluid filtration processes and transport of radionuclides in a three-dimensional crack and pore space in the variably deformed and metasomatically altered crystalline rocks was substantiated.
