Lineament Length and Density Analyses Based on the Segment Tracing Algorithm: A Case Study of the Gaosong Field in Gejiu Tin Mine, China

Abstract

This study used the Segment Tracing Algorithm (STA) to extract lineaments from remotely sensed images. A computer program was then written to calculate the lineament densities and lengths. In Gaosong field, 3,233 lineaments were extracted based on a 200 m × 200 m grid size. The results indicate that most lineaments lengths are between 30 m and 50 m, and the number of lineaments within each cell ranges from 1 to 6. Areas with high distributions exist on both sides of the central region. According to the contour map of lineament length, the maximum lineament length is 380 m, and the minimum length is 30 m. The contours mainly extend in two directions, including NE and NW trends. This is consistent with the prominent NE and NW strike faults that prevail in the mining area. The results are similar to those obtained in the Machishui ore block, which has become a mine production area. High values of lineament length and density in the contour map of Gaosong field may be associated with hydrothermal tin mineralization in the study area. The results of this study potentially provide a new approach to mineral exploration in the early stage of geological prospecting.

Delineation of Groundwater Potential Zones (GWPZs) in a Semi-Arid Basin through Remote Sensing, GIS, and AHP Approaches

“…Lineaments are straight or nearly straight landforms that are enhanced by the terrain's permeability and extensively spread over the Earth's surface [62,63]. They reflect a general manifestation of underground fractures, faults, or joints with intrinsic permeability characteristics and porosity [6,64,65].…”

Fractal and Multifractal Characteristics of Lineaments in the Qianhe Graben and Its Tectonic Significance Using Remote Sensing Images

“…Previous algorithms related to lineament extraction mainly focused on the extraction of the ridgeline and the valley line, fracture zone, and geological geometry edge in remote sensing images and DEMs (e.g., [19][20][21][22][23]57,58]); therefore, the anomaly gradient pixels can be regarded as lineaments after grayscale transformation. Specifically, on the basis of the filter, edge detection, threshold, etc., the algorithms can be divided into the segment tracing algorithm (STA), LINE algorithm in PCI software, and tensor voting.…”

Lineament Extraction using Gravity Data in the Citarum Watershed

“…Remotely sensed data, including satellite imaging, and airborne geophysical data, are usually used to map regionals (Yeomans et al, 2019). In addition, these lineaments may be used as a basis to infer the region's structural geology, with implications for mineral exploration (Moore and Camm, 1982;James et Moore, 1985;Ni et al, 2016;Verdiansyah, 2019), oil exploration (Peña and Abdelsalam, 2006). (Rutzinger et al, 2007).…”
