Abstract

For the current geological mapping of individual territories, remote sensing and geographic information system (GIS) technologies are widely used. Taking the Fergana depression as an example, this paper aims to determine the possibilities of using remote sensing materials for mapping structural and geomorphological elements. Landsat-8 satellite imagery obtained on 11 spectral channels was used to highlight the decoding features. Fault zones, lineament zones, various uplifts, depressions, and structural material complexes of different ages were identified. Based on the in-depth analysis of geological and geophysical data, a geological schematic map of the Fergana depression was developed. Using geological landscape and automated methods for deciphering space images, the main neotectonic elements of the Fergana depression were identified: the southern step, northern marginal slope, central graben-syncline, flexure-fault zones, local anticlinal zones, individual uplifts/depressions, and local shear zones. The results show a neotectonic map of the study area, which can be used as a tectonic basis for prospecting, seismic zoning mapping, and geological engineering development.

基于空间图像解释的新构造要素填图的可能性——以费尔干纳坳陷为例

目前，遥感和地理信息系统(GIS)技术被广泛应用于个别地区的地质填图。本文以费尔干纳凹陷为例，探讨利用遥感资料进行构造地貌要素制图的可能性。利用11个光谱通道获得的Landsat-8卫星图像来突出解码特征。发现了不同时代的断裂带、界线带、各种隆升、凹陷和构造物质复合体。在深入分析地质和地球物理资料的基础上，绘制了费尔干纳坳陷地质简图。利用地质景观和空间图像自动解码方法，确定了费尔干纳坳陷的主要新构造要素:南台阶、北缘斜坡、中央地堑-向斜、弯曲断裂带、局部背斜带、个别隆升/凹陷和局部剪切带。结果显示出研究区新构造图，可作为找矿、地震区划填图和地质工程开发的构造依据。
