Definition

Linear set of graben, fissures, and related fractures of tectonic (extensional) or magmatic (underlying dikes) origin.

Category

A type of lineament system (Venus)

Synonyms

Linear graben-fissure system; Straight lineament system

Description

A system of graben, fissures, and related fractures in linear (straight subparallel) systems that often occur in crosscutting sets. They can be traced for hundreds of kilometers up to perhaps 3,000 km or more (Ernst et al. 2003). Some may be linear on a local scale but actually belong to regional radiating systems (cf. Grosfils and Head 1994; Ernst et al. 2003; Hansen and Olive 2010). Linear lineament systems may be underlain by dikes or have a purely tectonic (extensional) origin.

Subtypes

Potential subtypes can be distinguished based on local characteristics or regional context.

Subtypes Regarding Local Characteristics

Subtypes can be distinguished on the basis of density of fracturing. For instance, the map unit “fracture belts”...
