What sets topographic relief in extensional footwalls? (2005)
Journal Article
Densmore, A., Dawers, N., Gupta, S., & Guidon, R. (2006). What sets topographic relief in extensional footwalls?. Geology, 33(6), 453-456. https://doi.org/10.1130/g21440.1

We use three large normal fault arrays in the northeastern Basin and Range Province, western United States, to document catchment development and relief production during fault growth. Fault slip and slip rates increase systematically along strike fr... Read More about What sets topographic relief in extensional footwalls?.

Evidence for Cenozoic tectonic deformation in SE Ireland and near offshore (2004)
Journal Article
Cunningham, M., Phillips, W., & Densmore, A. (2004). Evidence for Cenozoic tectonic deformation in SE Ireland and near offshore. Tectonics, 23(6), Article TC6002. https://doi.org/10.1029/2003tc001597

An integrated study of topography, bathymetry, high-resolution aeromagnetic data, and structural observations demonstrates significant Cenozoic fault activity in SE Ireland. Tectonically generated knickpoints and reddened fault breccias along topogra... Read More about Evidence for Cenozoic tectonic deformation in SE Ireland and near offshore.

Footwall topographic development during continental extension (2004)
Journal Article
Densmore, A., Dawers, N., Gupta, S., Guidon, R., & Goldin, T. (2004). Footwall topographic development during continental extension. Journal of Geophysical Research, 109, https://doi.org/10.1029/2003jf000115

We examine the progressive development of footwall topography associated with a set of active normal faults in the northeastern Basin and Range Province of the western United States. Fault length and displacement increase monotonically from northeast... Read More about Footwall topographic development during continental extension.

Landscape evolution at extensional relay zones (2003)
Journal Article
Densmore, A., Dawers, N., Gupta, S., Allen, P., & Gilpin, R. (2003). Landscape evolution at extensional relay zones. Journal of Geophysical Research, 108(B5), Article 2273. https://doi.org/10.1029/2001jb001741

It is commonly argued that the extensional relay zones between adjacent crustal-scale normal fault segments are associated with large catchment-fan systems that deliver significant amounts of sediment to hanging wall basins. This conceptual model of... Read More about Landscape evolution at extensional relay zones.

Evolution of the Longmen Shan Foreland Basin (Western Sichuan, China) during the Late Triassic Indosinian Orogeny (2003)
Journal Article
Li, Y., Allen, P., Densmore, A., & Xu, Q. (2003). Evolution of the Longmen Shan Foreland Basin (Western Sichuan, China) during the Late Triassic Indosinian Orogeny. Basin Research, 15(1), 117-138. https://doi.org/10.1046/j.1365-2117.2003.00197.x

The Longmen Shan Foreland Basin developed as a flexural foredeep during the Late Triassic Indosinian orogeny, spanning the time period c. 227–206 Ma. The basin fill can be divided into three tectonostratigraphic units overlying a basal megasequence b...

Evidence for post-early Eocene tectonic activity in southeastern Ireland (2003)
Journal Article
Cunningham, M., Densmore, A., Allen, P., Phillips, W., Bennett, S., Gallagher, K., & Carter, A. (2003). Evidence for post-early Eocene tectonic activity in southeastern Ireland. Geological Magazine, 140(2), 101-118. https://doi.org/10.1017/s0016756802007240

The role played by Cenozoic deformation in denudation and landscape development in Ireland has historically been difficult to assess because of the lack of widespread pre-glacial Cenozoic deposits onshore. Here we combine analysis of apatite fission-... Read More about Evidence for post-early Eocene tectonic activity in southeastern Ireland.

Topographic fingerprints of bedrock landslides (2000)
Journal Article
Densmore, A., & Hovius, N. (2000). Topographic fingerprints of bedrock landslides. Geology, 28(4), 371-374. https://doi.org/10.1130/0091-7613%282000%2928%3C371%3Atfobl%3E2.0.co%3B2

Bedrock landslides in mountainous regions may be triggered by either storms or earthquakes; the dominant mechanism in a region affects both landscape evolution and landslide hazard. We describe a simple observational test to distinguish between storm... Read More about Topographic fingerprints of bedrock landslides.

Sediment flux from an uplifting fault block (2000)
Journal Article
Allen, P., & Densmore, A. (2000). Sediment flux from an uplifting fault block. Basin Research, 12(3-4), 367-380. https://doi.org/10.1111/j.1365-2117.2000.00135.x

The stratigraphy of rift basins is a direct result of sediment liberation and transport through catchment–fan systems whose dynamics are controlled by both external and internal factors. We investigate the response of catchment–fan systems establishe... Read More about Sediment flux from an uplifting fault block.

Development of mountainous topography in the Basin Ranges, U.S.A (1999)
Journal Article
Ellis, M., Densmore, A., & Anderson, R. (1999). Development of mountainous topography in the Basin Ranges, U.S.A. Basin Research, 11(1), 21-41. https://doi.org/10.1046/j.1365-2117.1999.00087.x

We use the landcape evolution model Zscape to explore quantitatively the development of mountainous topography in the Basin and Range province (formerly the Basin Ranges), USA, as a function of faulting, surface processes and microclimate. Many of th... Read More about Development of mountainous topography in the Basin Ranges, U.S.A.

The generation and degradation of marine terraces (1999)
Journal Article
Anderson, R., Densmore, A., & Ellis, M. (1999). The generation and degradation of marine terraces. Basin Research, 11(1), 7-19. https://doi.org/10.1046/j.1365-2117.1999.00085.x

Marine terraces are ephemeral planar landforms. While tectonic and climatic forcings responsible for the generation of existing marine terraces have operated for at least 1 Myr, terraces have been completely removed by erosion above a given altitude...
