Stratigraphy, Sedimentology and Palaeontology


You wouldn’t go in the early basement during the upper afternoon, don’t you?

I remember it perfectly. It was 13 years ago, while writing my first manuscript, I was first confronted with that thing that challenges a lot of junior stratigraphers, especially when they are not a native English: Geochronology vs. Chronostratigraphy! Or to simplify, how to properly distinguish time and time-rock units in your writings. Several papers have been published on this subject, out of w ...[Read More]

Tiny but powerful

Oceans are “populated” by millions of specimens of microscopic organisms which constitute the phytoplanktonic communities (e.g. diatoms, dinoflagellates, cyanobacteria and coccolithophorids). These tiny organisms are important indicators of the “health” of present oceans and their remains constitute important tracers of past paleoenvironmental conditions. The ocean is in fact the oldest and larges ...[Read More]

When lava meets water…

Pillow-palagonite complex forming as a result of hot lava entering a former river channel or lake in the Columbia River Flood Basalt Province, Washington State, USA (c. 15 My). Individual sediment packages were picked up from the bottom of the water body and trapped within the lava complex (see white arrow). Orange-brown palagonite is a type of clay which forms through the break-down of volcanic g ...[Read More]

EGU’s lost strata… what happens to conference carpets?

Being a stratigrapher or not, there’s one stratum you have all trod upon if you ever went to the General Assembly (GA), without probably noticing it. The uppermost unit of EGU’s GA floor, a ca. 5 mm thick layer with a soft rubbery texture and peculiar light-grey colour, outcropping over the whole poster halls: Carpet! Yes, the focus of this post is the carpet draping the GA’s floor wit ...[Read More]
