摘要

根据大量研究,断层的几何和运动学特征存在基本的和初始的比例关系。研究区域位于克尔曼煤炭省北部。统计计算包括:测量每个单位区域的断层表面密度和区域划分,确定主导断层的方向,并评估长度位移、走向位移和走向长度之间的关系。根据图表,最高断裂密度与研究区的中部(B区)有关,因为该区域位于四条主要断层和砂岩组合之间。走向长度参数计算为(y=0.0478x+11.54),R平方率计算为(R=0.341),走向位移计算为(y=2.68x+147.4),R-平方率为(R=0.65),长度位移计算为:。研究表明,研究区断裂和断层密度的增加可归因于复杂的地质结构、初始断层的形成和长期的渐进变形。由于变形堆积和多个结构(如断层、褶皱和剪切带)的形成,使裂缝密度和地形不断增加,并相互作用。长度走向和走向位移参数的比较,代表了绘制数据中聚类的相似性。尽管它们彼此有很多相似性,但没有显示出可靠的相关性,这可能表明它们是异步创建的。

The power law scaling, geometric and kinematic characteristic of faults in the Northern part of the Kerman Coal Province (KCP), Iran
According to numerous studies, there are basic and initial scaling relationship for the geometric and kinematic characteristics of faults. The study area is located in the northern part of the Kerman coal province. The statistical calculations are consisting of:  measure the surface density of faults per unite area and division of the area, determining the direction of the dominant faulting and evaluating the relationship between length-displacement, strike-displacement and strike-length. Based on diagrams, the highest fracture density is related to the middle portion (B zone) of study area because that enclosed between the four main faults and sandstone rock assemblage. The relationship between strike-length parameter is calculated as (y=0.0478x + 11.54), and R-squared rate is (R=0.341), strike-displacement is calculated as (y=2.68x + 147.4) and R-squared rate is (R=0.65) and length-displacement is calculated as (y= 243.58 x0.0336) and R-squared rate is (R=0/022). It was determined that increasing the density of fractures and faulting in the study area can be attributed to the complex geological structure, the formation of initial faults and long term progressive deformation. Due to deformations accumulation and formations of multiple structures (like faults, folds and shear zones), have Increasing the fracture density, and topography, and has interacted with together. Comparison the length-strike and strike-displacement parameters, represents a similarity on the clustering in the plotted data Despite that they have many similarities to each other, does not show a dependable dependence, this may indicate their asynchronous creation.
