Bullet impacts in building stone excavate approximately conical craters, with dimensions that are controlled by target material (2022)
Journal Article

Bullet impacts are a ubiquitous form of damage to the built environment resulting from armed conflicts. Bullet impacts into stone buildings result in surficial cratering, fracturing, and changes to material properties, such as permeability and surfac...

Surface damage from perpendicular and oblique bullet impacts in stone (2022)
Journal Article

Controlled experiments were conducted to investigate the surface damage caused by perpendicular and oblique impacts of bullets into sandstone and limestone targets. Individual bullets fired in conditions simulating modern rifles at typical combat dis... Read More about Surface damage from perpendicular and oblique bullet impacts in stone.

Influence of landscape moisture sources and topography on rock weathering patterns associated with wildfire (2022)
Journal Article

From 9 March 2015, a wildfire burned an area of 25.7 km2, or approximately half of the Jonkershoek catchment (Western Cape, South Africa), over the course of 3 days. During this period, large areas of fynbos and commercial forest plantations were raz...

The efficiency of elemental geochemistry and weathering indices as tracers in aeolian sediment provenance fingerprinting (2021)
Journal Article

Confirmation of cost-effective and reliable tracers for aeolian sediment (sand dune) source fingerprinting warrants further research. Accordingly, the main objective of the work reported in this paper was to investigate the efficiency of weathering i...

Surface and subsurface damage caused by bullet impacts into sandstone (2021)
Journal Article

The shift of armed conflicts to more urbanised environments has increased the risk to cultural heritage sites. Small arms impacts are ubiquitous in these circumstances, yet the effects and mechanisms of damage caused are not well known. A sandstone t...

Sediment source fingerprinting: Benchmarking recent outputs, remaining challenges and emerging themes (2020)
Journal Article

Purpose: This review of sediment source fingerprinting assesses the current state-of-the-art, remaining challenges and emerging themes. It combines inputs from international scientists either with track records in the approach or with expertise relev...

Image is everything: Educator awareness of perceived barriers for students with physical disabilities in geoscience degree programs (2019)
Journal Article

This exploratory pilot study builds on the image issues associated with geoscience degrees (namely physical geography and geology) and the potential obstacles this creates for prospective applicants with physical disabilities; departmental faculty ma...

Integrating structure-from-motion photogrammetry into rock weathering field methodologies (2019)
Journal Article

© 2019 John Wiley & Sons, Ltd. Despite recent rapid advances in the field of structure-from-motion (SfM) photogrammetry, the use of high-resolution data to investigate small-scale processes is a relatively underdeveloped field. In particular, rock... Read More about Integrating structure-from-motion photogrammetry into rock weathering field methodologies.

Permeability and surface hardness surveying of stone damaged by ballistic impact (2019)
Journal Article

Recent instances of the destruction of cultural assets in conflict zones have demonstrated the need to develop methods which will allow for the assessment of damage to heritage stone in the field. In particular, non-destructive methods would be inval... Read More about Permeability and surface hardness surveying of stone damaged by ballistic impact.

Bullet impacts and built heritage damage 1640–1939 (2018)
Journal Article

© 2018, The Author(s). Conflict damage to heritage has been thrust into the global spotlight during recent conflict in the Middle East. While the use of social media has heightened and enhanced public awareness of this ‘cultural terrorism’, the occur... Read More about Bullet impacts and built heritage damage 1640–1939.
