Eigenvector of gravity gradient tensor for estimating fault dips considering fault type

Progress in Earth and Planetary Science, 2017
The dips of boundaries in faults and caldera walls play an important role in understanding their formation mechanisms. The fault dip is a particularly important parameter in numerical simulations for hazard map creation as the fault dip affects ...

A comparison of Landsat 8 (OLI) and Landsat 7 (ETM+) in mapping geology and visualising lineaments: A case study of central region Kenya

, 2015
Availability of multispectral remote sensing data cheaply and its higher spectral resolution compared to remote sensing data with higher spatial resolution has proved valuable for geological mapping exploitation and mineral mapping.

Investigation of the fluid flow dynamic parameters for Newtonian and non-Newtonian materials: an approach to understanding the fluid flow-like structures within fault zones

Earth, Planets and Space, 2017
To understand the fault zone fluid flow-like structure, namely the ductile deformation structure, often observed in the geological field (e.g., Ramsay and Huber The techniques of modern structure geology, vol.

Geology of faults exposed in trenches in Crater Flat, Nye County, Nevada [PDF]

Open-File Report, 1983
Study of three trenches excavated across two faults along the eastern edge of Crate Flat indicates that the main fault movement offset unit QTa in trench 1 at least 2.4 m down to the west, and occurred about 1.1 m.y. ago, as indicated by included basalt ash.

Geology of the eastern tip of the El Tordell Fault, Southern Pyrenees

Journal of Maps
Along strike variations of frontal structures at fold and thrust belts allow us deciphering the evolution of contractional structures at early stages of deformation but also, how processes such as salt mobilisation, thrust emplacement, and folding develop.

Numerical investigation of casing shear deformation due to fracture/fault slip during hydraulic fracturing

Energy Science & Engineering, 2020
The frequent occurrence of casing failure has significantly affected the development of shale gas in the Sichuan Basin. Based on engineering and geology analyses, natural fracture/fault slip leads to casing shear deformation during hydraulic fracturing ...
