Mapping and comparison of landsat lineaments with gravity trends in West Tennessee

Since it is indicated that earthquakes resulting from faulting are of fairly common occurrence in West Tennessee, and also that it is difficult to recognize faulting within the alluvial valley because of the unconsolidated nature of the sediments, it was considered necessary to study the lineament pattern of the area.

The study contains evaluation of Landsat imagery for different spectral bands, seasons, image enhancement, and photointerpretation techniques.

A method for finding gravity trends was applied to the newest gravity maps of West Tennessee.

Statistical programs that express the main trends of the Landsat and gravity lineaments in rose diagrams and histograms were used.

Finally, the results of the study of Landsat and gravity lineaments were compared to the tectonic model of West Tennessee.
