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.

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.

Evolution of the Longmen Shan Foreland Basin (Western Sichuan, China) during the Late Triassic Indosinian Orogeny (2003)
Journal Article

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...

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

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...

Landsliding and the evolution of normal fault-bounded mountains (1998)
Journal Article

Much of the tectonic and climatic history in high-relief regions, such as the mountains of the western U.S. Basin and Range province, is contained in the morphology of hillslopes, drainage networks, and other landforms that range in scale from 10−1 t...

Hillslope evolution by bedrock landslides (1997)
Journal Article

Bedrock landsliding is a dominant geomorphic process in a number of high-relief landscapes, yet is neglected in landscape evolution models. A physical model of sliding in beans is presented, in which incremental lowering of one wall simulates baselev... Read More about Hillslope evolution by bedrock landslides.

Tectonic geomorphology of the Ash Hill fault, Panamint Valley, California (1997)

Panamint Valley, in eastern California, is an extensional basin currently bounded by active, dextral-normal oblique-slip faults. There is considerable debate over the tectonic and topographic evolution of the valley. The least-studied structure, the...
