Transmitted signals are also received from a line of shot locations on the other side of the area. The signals received are processed according to an adaptive lag-summing technique to give a map showing the geological faults in the seam.DAVID J. BUCHANAN...

What do the numbers on a topographic map represent? Are footprints trace fossils? Is geologic mapping a binder event? Does the geological time scale use sedimentary rocks? Are rock layers still continuous in a reverse fault? What are the types of geological maps? How do you identify geological...

Map traces of the frontal strands indicate a shallower dip than the master fault and are therefore proposed to be footwall shortcut thrusts.doi:10.1080/00288306.2001.9514953N. J.LitchfieldDepartment of Geology, University of Otago, P.O. Box 56, Dunedin, New ZealandInstitute of Geological & ...
fault blocks within crystalline basement in a manner similar to the terracing technique developed by Cordell and McCafferty at the USGS in 1989, which transforms smoothly varying magnetic anomalies into domains of uniform properties separated by sharp boundaries that look more like a geological map. ...

To the immediate east of the source region, there is a zone of concentrated geological strain, called the eastern margin of the Japan Sea. While part of the source region lay beneath the onshore area, the surface traces of the faults (Inoue and Okamura 2010) that caused this earthquake ...
We use new aeromagnetic data to map structure, delineate faults, and infer cumulative offsets across the San Andreas Fault system between the Mendocino Triple Junction and Clear Lake. Difficult access, poor outcrops, abundant landslides, dense vegetation, and rugged terrain make it hard to use tra...
