TS Must-Read – Lister and Davis (1989) The origin of metamorphic core complexes and detachment faults formed during Tertiary continental extension in the northern Colorado River region, USA

Lister and Davis (1989) is a seminal article for core complexes and detachment faults, cited well over a thousand times. The authors describe geometry and kinematics of core complexes, cropping out in the USA, which result from lithosphere extension. The paper carefully describes the main detachment fault separating lower plate from upper extending plate and discusses the role of granitoid intrusi ...[Read More]

Cryo-adventures – Undertaking Cryo-Fieldwork in a Global Pandemic!

Have you ever wondered what undertaking cryo-fieldwork in a glacial environment typically involves? Well, what about undertaking cryo-fieldwork in a glacial environment during a global pandemic?! Read on to find out all about the challenges I faced on my recent trip to Iceland in July 2021… Fieldwork Preparation As this previous blog post highlights, undertaking cryo-fieldwork requires a significa ...[Read More]

The Sassy Scientist – Down to the Core

We all want our five minutes in the spotlight. It could be the long-awaited moment you finally get to give an oral presentation at EGU, in front of an audience eager to absorb every single word that comes out of your mouth and every single slide like they are solving all open issues in all the geosciences. But not all research fields are created equal and, let’s face it, some fields seem to ...[Read More]

Earthquake Watch July: Perryville, Alaska

One year ago, we started a series of blog posts synthesising the main results and discussions about the most significant earthquakes recorded recently, previously called “Earthquake of the month” and now known as “Earthquake Watch.” In our first edition, we reported on the 2020 Simeonof earthquake M 7.8 that occurred in Alaska (read here), and today we return to the same region with another intere ...[Read More]

Three reasons why Forest-Fires worsen with climate change

The brand-new IPCC AR6 report clearly states that “Unless there are immediate, rapid and massive reductions in greenhouse gas emissions, limiting warming to around 1.5°C, or even 2°C, will be out of reach”. Although as human beings we do not perceive changes in global Earth average temperatures as a threat to our lives, the IPCC report also states that extreme weather events will worsen; actually ...[Read More]

Sediment in the deep ocean. Part 2: thermohaline currents that shape the seafloor

In Part 1 we differentiated between (1) shallow-marine tide-related currents from (2) purely gravitational sediment-laden currents. We could add that the former are periodic, as they are controlled by the effect of the Moon and Sun gravitational fields on the oceanic water as the Earth revolves, while the latter are sort of ‘spontaneous’ currents driven by the Earth gravitation field on sedi ...[Read More]

When not Digging Through Code, Dig Rocks

 Most of us have been directly or indirectly involved in outreach activities, often relying on shiny rocks to capture people’s fascination. This week, Aaron Van Alstine, a member of the Memphis Archaeological and Geological Society, a passionate rockhounder, and moderator of the sub-reddit on radioactive rocks, shares his views on why all earth scientists need a rock collection and how to st ...[Read More]

Tektonika Diamond Open Access Journal

In a nutshell Tektonika is a community-led Diamond Open Access journal (DOAJ) for tectonics and structural geology launching in early 2022. The journal will publish high quality peer-reviewed research that is free for authors and readers, offering an alternative to long-standing publishing models that conceal knowledge dissemination behind paid subscriptions. Community involvement is at Tektonika’ ...[Read More]
