Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain geological faults and their types, describe how faults relate to earthquakes and rifts, support hazard and mapping questions, and separate other senses of fault.

In geology, a fracture in rock along which the two sides have moved relative to each other, classified as normal, reverse, thrust and strike-slip faults by the direction of movement, ranging from small offsets to plate boundaries and continental rift systems such as the Canadian Arctic Rift, with active faults capable of generating earthquakes; faults are mapped and studied in structural geology and seismology and inform hazard assessment and resource exploration, and the word has many other senses.

What it is for: Fractures in rock with displacement.

It can be explain fault types; relate to earthquakes and rifts; support hazard questions; separate other senses.

Distinguishing features

Displacement

Movement classification

Earthquake source

Multiple senses

What it looks like

Displaced rock layers and scarps at the surface.

How it is recognised

Fracture with relative movement

Normal, reverse, strike-slip

A joint is a fracture without displacement; a fold is a bend
