TS Must-read – Dewey (1988) Extensional collapse of orogens

After building orogens with Dewey and Bird (1970) and extending them during building with Platt (1986), Dewey (1988) explores the lifetime of orogens in their last breath: their extensional collapse. Simple considerations on how to form a normally-thick continental crust (30-40 km) from a thickened continental domain (50-60 km) indicate that erosion of the topography alone is far from being suffic ...[Read More]

Connecting the Networks for a better Understanding of the Ocean

Connecting the Networks for a better Understanding of the Ocean

Research in many scientific disciplines can be done singlehandedly by learning from the printed pages, solving complex equations and analyzing the data while sitting alone in an office. But observational ocean science research demands an involved team effort to get meaningful insights of the ocean. This is primarily because: The Ocean is vast – it is humanly impossible for anyone to conduct resear ...[Read More]

Meet the new Geodesy Science Officer – Part 2

In the past weeks you have met the president, deputy president and one science officer of the Geodesy division. Last but not least, we introduce you today to the second science officer: Xavier Collilieux. He also answered a few questions for us (including where his favourite place in Vienna is). Curious to find out? Then read below.   What is your position within the EGU and/or the Geodesy Di ...[Read More]

Earthquakes within the plates

Earthquakes within the plates

As fascinating as the plate tectonics and its accompanying dynamics are, continental interiors are no quiescent zones. The tectonics within these interiors are apparent in the occurrence of numerous intraplate earthquakes, and this week, EGU blog editor Arushi Saxena briefly discusses them and their mechanisms. Earthquakes are a fairly common occurrence here on Earth’s crust. Although most are ess ...[Read More]

Features from the Field: Stretching Lineations

Deep beneath our feet, deformation of rocks at high temperature produces impressive structures such as shear zones, that localize the movement of two volumes of rock with respect to one another. Shear zones are strongly deformed bands with strongly foliated structures (i.e., with rocks that look like a pile of leaves) and kinematic indicators, such as S-C fabrics, that tell us geologists which way ...[Read More]

The Sassy Scientist – The Secret Art Of Keeping Up-To-Date

It’s easy to feel overwhelmed by the impressive speed at which new science is published. How to keep up with all this is an art that few have mastered. Rami is looking for some pointers: Which are the must-follow journals to keep up to date with new geodynamic research? Dear Rami, Carefully checking the table of contents of freshly printed issues of your favourite journals is obviously the most mo ...[Read More]

The Norwegian Polar Institute

It is a pleasure for the EGU Cryoblog team to present a new post category: Cryo-institutes around the world! There are many institutes working on cryosphere-related research spread around the world. The aim of this new category is to highlight the cool research that is carried out at these institutes, showing off our multi-faceted cryo-related science. In this opening post, Ashley Morris will pres ...[Read More]

Rare Earth Elements…..in olivine?

The Rare Earth Elements, or REEs, are really important. This is a group of elements including neodymium (used to create strong magnets), cerium (used in catalytic converters), lanthanum (used in electric car batteries), lutetium (used in oil refinery), with the uses of REEs increasing continuously. At the moment, the majority of the world’s supply of REEs comes from a single deposit in Inner ...[Read More]

The Lutz Creek watershed of Barro Colorado Island, Panama

The Lutz Creek watershed, administered by the Smithsonian Tropical Research Institute (STRI) on Barro Colorado Island (BCI), is one of the longest continually monitored, micro-catchments in the neotropics. This catchment is central to the long-term climate and hydrological monitoring program that STRI has operated on BCI since 1972. The information derived from this program plays an essential role ...[Read More]
