Extensional environments like the Basin and Range are characterized by listric normal faulting, or faults that level out with depth. Opposing normal faults link at depth producing a horst and graben geometry, where horst refers t…

WebAccretion is the process in which material from the outer plate and trench (during the periods of discontinuous subduction) is removed and added to the outer continental margin or by other mechanisms such as imbricate thrusting or a combination of folding and thrusting (Karig, 1974; Karig and Sherman, 1975).
