What is a lineament map?

Lineament Density Map: Lineaments are structurally controlled linear or curvilinear features, which are identified from the satellite imagery by their relatively linear alignments. These features express the surface topography of the underlying structural features.

What is meant by lineament?

Definition of lineament 1a : an outline, feature, or contour of a body or figure and especially of a face —usually used in plural. b : a linear topographic feature (as of the earth) that reveals a characteristic (such as a fault or the subsurface structure)

What is meant by lineament in geology?

A lineament is a linear feature in a landscape that is an expression of an underlying geological structure such as a fault, fracture, or joint. Lineaments are generally referred to in the analysis of remote sensing of fractures or structures.

What is lineament analysis?

Lineaments are linear features which provide information about the underlying geological structure. Lineament is one of the most important features showing subsurface elements or structural weakness such as faults and is usually extracted by visual analysis of enhanced image data.

What is the difference between fault and lineament?

One distinction that needs to be made between faults and lineaments is based on the respective scopes considered: faults tell the geologic history of a small, limited area within a relatively shallow depth while lineaments, unfortunately so elusive, narrate in lesser detail a much broader and more pertinent structural …

What is lineament in earthquake?

A lineament is a linear feature in a landscape dictated by an underlying geological structure such as a fault. Context: According to a recent study, an unfamiliar lineament is one factor behind frequent earthquakes in northern Assam’s Sonitpur area.

What is a fault lineament?

A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will appear as a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features.
