How great is the Great Glen Fault? Open
A popular conceptual tectonic model envisages the Great Glen Fault to be part of a sinistral strike-slip system active during the mid-Silurian to early Devonian with c. 700 km of displacement. Here we use sedimentological, geochemical and …

Evidence, or not, for the late Tonian break-up of Rodinia? The Dalradian Supergroup, Scotland Open
The Tonian–Cambrian Dalradian Supergroup in Scotland is a siliciclastic–carbonate succession that can be up to 10 km thick. The consensus view is that its lower part, the mid- to late Tonian Grampian and Appin groups, formed in rift basins…

The grandest of them all: the Lomagundi–Jatuli Event and Earth's oxygenation Open
The Paleoproterozoic Lomagundi–Jatuli Event (LJE) is generally considered the largest, in both amplitude and duration, positive carbonate C-isotope ( 13 C carb ) excursion in Earth history. Conventional thinking is that it represents a g…

A template for an improved rock-based subdivision of the pre-Cryogenian timescale Open
The geological timescale before 720 Ma uses rounded absolute ages rather than specific events recorded in rocks to subdivide time. This has led increasingly to mismatches between subdivisions and the features for which they were named. Her…

Beyond one-way determinism: San Frediano’s miracle and climate change in Central and Northern Italy in late antiquity Open
Integrating palaeoclimatological proxies and historical records, which is necessary to achieve a more complete understanding of climate impacts on past societies, is a challenging task, often leading to unsatisfactory and even contradictor…

The Lomagundi-Jatuli Event and Earth’s oxygenation Open
The Palaeoproterozoic Lomagundi-Jatuli Event (LJE) is the largest positive carbonate C-isotope ( δ13Ccarb) excursion in Earth history. Conventional thinking is that it represents a perturbation of the global C cycle between c. 2.3–2.1 Ga l…

Ruby Deposits: A Review and Geological Classification Open
Corundum is not uncommon on Earth but the gem varieties of ruby and sapphire are relatively rare. Gem corundum deposits are classified as primary and secondary deposits. Primary deposits contain corundum either in the rocks where it crysta…

Fluid and metal sources in the Fäboliden hypozonal orogenic gold deposit, Sweden Open
To model the formation of orogenic gold deposits, in a global perspective, it is important to understand the ore-forming conditions not only for deposits hosted in greenschist facies rocks but also in amphibolite facies. The Paleoproterozo…

The nature and age of Mesoproterozoic strike-slip faulting based on Re–Os geochronology of syntectonic copper mineralization, Assynt Terrane, NW Scotland Open
In ancient basement regions such as the Lewisian Complex, NW Scotland, the ages of brittle deformation events are commonly poorly constrained owing to a lack of datable fills. An array of NW–SE sinistral and antithetic east–west dextral fa…
