An Analysis of Failure Mechanism constraints on Pre-Failure Rock Block Deformation using TLS and Roto-Translation Methods
(2017-08-31)Rockfall hazards increase the risk of train derailment along railway corridors in western Canada. In this study, repeated Terrestrial Laser Scanning (TLS) datasets were collected every 2-3 months at three different sites ... -
Copper Isotopic Analysis in Geological and Biological Reference Materials by MC‐ICP‐MS
(Wiley, 2020-01-24)The characterisation of relative copper isotope amount ratios (δ65Cu) helps constrain a variety of geochemical processes occurring in the geosphere, biosphere and hydrosphere. The accurate and precise determination of δ65Cu ... -
Effects of Sampling Interval on the Frequency-Magnitude Relationship of Rockfalls Detected from Terrestrial Laser Scanning using Semi-Automated Methods
(2017-02-13)Using change detection and semi-automated identification methods, it is possible to extract detailed rockfall information from terrestrial laser scanning data to build a database of events, which can be used in the development ... -
An Epeiric Glass Ramp: Permian Low-Latitude Neritic Siliceous Sponge Colonization and its Novel Preservation (Phosphoria Rock Complex)
(Elsevier, 2019-11-29)Glass ramps are shallow-marine depositional settings in which siliceous sponge meadows dominate coastal environments. They are increasingly recognized throughout the Phanerozoic and represent a biosiliceous counterpart to ... -
Glimpses of Oceanic Lithosphere of the Challenger Deep Forearc Segment in the Southernmost Marianas: The 143°E transect, 5800–4200 m
(Wiley, 2020-06-16)We studied nine samples of igneous rocks from the inner wall of the Mariana Trench above the Challenger Deep from 4150 to 6100 m depth recovered by manned submersible and ROV. Samples from two regions that bracket the Moho ... -
High‐resolution unmanned aerial vehicle aeromagnetic surveys for mineral exploration targets
(Wiley, 2020-01)Recent advancements in geophysical exploration have been realized through reliably integrating unmanned aerial vehicle platforms with lightweight, high‐resolution magnetometer payloads. Unmanned aerial vehicle aeromagnetic ... -
Phosphorites, Glass Ramps and Carbonate Factories: The Evolution of an Epicontinental Sea and a Late Palaeozoic Upwelling System (Phosphoria Rock Complex)
(Wiley, 2020-03-11)The Permian Phosphoria Rock Complex of the western USA contains an enigmatic assemblage of bioelemental rocks (i.e. phosphorites and cherts) that accumulated in a depositional system with no modern analogue. This study ... -
Pleistocene aeolianites at Cape Spencer, South Australia; record of a vanished inner neritic cool-water carbonate factory
(2016-02-17)Aeolianites are integral components of many modern and ancient carbonate depositional systems. Southern Australia contains some of the most impressive and extensive late Cenozoic aeolianites in the modern world. Pleistocene ... -
Relating Ediacaran Fronds
(Cambridge University Press, 2017)Ediacaran fronds are key components of terminal-Proterozoic ecosystems. They represent one of the most widespread and common body forms ranging across all major faunal localities and time slices postdating the Gaskiers ... -
Review of Close-Range Three-Dimensional Laser Scanning of Geological Hand Samples
(Elsevier, 2020)The morphological study of geological hand samples has a wide variety of applications in the geosciences, which is conventionally accomplished by measuring the distance between features of interest on the sample’s surface. ... -
Seasonal variation of arsenic and antimony in surface waters of small subarctic lakes impacted by legacy mining pollution near Yellowknife, NT, Canada
(Elsevier, 2019-09-20)The seasonal variation in lake water arsenic (As) and antimony (Sb) concentrations was assessed in four small (<1.5 km2) subarctic lakes impacted by As and Sb emissions from legacy mining activities near Yellowknife, ... -
Slow cooling versus episodic fluid injections: Deciphering the Caledonian orogeny in Vestvågøy, Lofoten islands, Norway
(Wiley, 2019-03-23)The determination of the thermal (temperature–time) histories of high-P metamorphic terranes has been commonly based on the concepts of slow cooling and closure temperatures. In this paper, we find that this approach cannot ...
