Thermochemical structure of the Superior craton and environs: Implications for the evolution and preservation of cratonic lithosphere [PDF]

open access: goldGeochemistry, Geophysics, Geosystems
The Archean Superior craton was formed by the assemblage of continental and oceanic terranes at ∼2.6 Ga. The craton is surrounded by multiple Proterozoic mobile belts, including the Paleoproterozoic Trans‐Hudson Orogen which brought together the Superior

Time-dependent frictional properties of granular materials used in analogue modelling: implications for mimicking fault healing during reactivation and inversion [PDF]

open access: yesSolid Earth, 2023
Analogue models are often used to model long-term geological processes such as mountain building or basin inversion. Most of these models use granular materials such as sand or glass beads to simulate the brittle behaviour of the crust.

Permian Large Igneous Provinces and Their Paleoenvironmental Effects

open access: yesGeophysical Monograph Series, Page 417-434., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Application of active-source surface waves in urban underground space detection: A case study of Rongcheng County, Hebei, China

open access: yesEarth and Planetary Physics, 2022
Active-source surface wave exploration is advantageous because it has high imaging accuracy, is not affected by high-speed layers, and has a low cost; thus, it has unique advantages for investigating shallow surface structures.

Surface wave imaging using deep reflection seismic data: a study on the Cuonadong dome

open access: yesEarth, Planets and Space, 2022
As interference waves in deep reflection data processing, surface waves are often suppressed as noise, but surface waves carry considerable underground media information, including structural information and the physical properties of rocks.

Kinematics and Convergent Tectonics of the Northwestern South American Plate During the Cenozoic

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The interaction of the northern Nazca and southwestern Caribbean oceanic plates with northwestern South America (NWSA) and the collision of the Panama‐Choco arc (PCA) have significant implications on the evolution of the northern Andes.
