[1] This work explores the control of fore-arc structure on segmentation of megathrust earthquake ruptures using coastal geomorphic markers. The Arauco-Nahuelbuta region at the south-central Chile margin constitutes an anomalous fore-arc sector in terms of topography, geology, and exhumation, located within the overlap between the Concepción and Valdivia megathrust segments. This boundary, howe...

Foreland basin development in the Andes of central Colombia has been suggested to have started in the Late Cretaceous through tectonic loading of the Central Cordillera. Eastward migration of the Cenozoic orogenic front has also been inferred from the foreland basin record west of the Eastern Cordillera. However, farther east, limited data provided by foreland basin strata and the adjacent East...

Acute poisonings with inorganic lead compounds are exceptionally rare. In all cases of diagnosis, there are two possible sources of error: failing to recognise lead poisoning when it is present, and mistaking other diseases for lead poisoning. If exposure history is carefully taken and proper laboratory techniques are employed, the diagnosis of lead poisoning should not be difficult. In the des...

The Atacama Desert, on the western margin of Central Andes, hosts some world's largest porphyry copper deposits (PCDs). Despite a hyperarid climate, many these PCDs have undergone secondary “supergene” enrichment, whereby has been concentrated via groundwater-driven leaching and reprecipitation, yielding supergene profiles containing valuable records weathering landscape evolution. We combine h...

Craton cores far from plate boundaries have traditionally been viewed as stable features that experience minimal vertical motion over 100–1000 Ma time scales. Here we show that the Fennoscandian Shield in southeastern Sweden experienced several episodes of burial and exhumation from ~1800 Ma to the present. Apatite, titanite, and zircon (U-Th)/He ages from surface samples and drill cores constr...
