Abstract

This paper successively reports on a methodology for investigating the orientation and morphogenetic characteristics of fault systems at four scale levels: kilometers, meters, centimeters, and millimeters. The research object is the Urtui granite massif in southeastern Transbaikalia west of the Streltsovska caldera, incorporating unique uranium deposits. The massif is composed of Late Riphean granites and granite gneisses variably affected by dynamometamorphic and hydrothermal–metasomatic alterations and is crosscut by numerous faults with traces of fluid activity from various tectogenesis episodes. The relationship between the geometric parameters of the fault systems, such as specific density and specific length, has been established. It is advisable to use these geostructural data for conceptual and numerical modeling of fluid filtration and radionuclide transport processes in the three-dimensional fractured–pore space of crystalline rocks, for reconstructing and modeling uranium ore formation, and using the geological space for the isolation of radioactive materials.

流体传导故障网络中的尺度效应

摘要

本文相继报道了一种用于研究断裂系统的方向和形态发生特征的方法，该方法在四个尺度级别：公里，米，厘米和毫米。研究对象是Streltsovska破火山口以西的Transbaikalia东南部的Urtui花岗岩地块，结合了独特的铀矿床。地块由晚瑞风花岗岩和花岗岩片麻岩组成，它们受动变变质和热液变质作用的变化影响，并且被众多断层横切，并伴有来自各种构造成因的流体活动痕迹。已经建立了诸如特定密度和特定长度之类的断层系统几何参数之间的关系。
