Recently, members of the VUB AMGC research group (PhD-student Matthias Sinnesael (FWO) and former PhD-student dr. David De Vleeschouwer (MARUM, Bremen)) visited prof. Miroslav Zivanovic from the department of Electrical and Electronic Engineering in UPNA, Pamplona. This visit is a part of an international collaboration between geologists and engineers who have joined their forces in the study of cyclic (paleo-) climate research. The geologists are experienced and interested in cyclostratigraphy while the engineers – also in collaboration with VUB professor Johan Schoukens from the ELEC research group - have an extensive knowhow in the field of signal processing.

Former AMGC Dr. David De Vleeschouwer heads new IGCP project “ IGCP 652, Reading Geologic time in Paleozoic Sedimentary Rocks”

IGCP = International Geosciences Programme Projects, funded by UNESCO

Major events punctuated the Paleozoic: ecological crises and diversifications, shifts in ocean chemistry, climatic changes, etc. One of the key-obstacles in understanding these events lays in the difficulty of providing precise estimates of the duration represented by a sequence of Paleozoic sedimentary rocks. This lack of temporal precision severely hampers the evaluation of forcing mechanisms and rates of climatic, ecological or biogeochemical changes in the Paleozoic. It is therefore essential to first improve the Paleozoic timescale to then unravel the history of the Paleozoic Earth system.

Laurine Burdorf (PhD student of Filip Meysman) recently won the ‘VLIZ Brilliant Marine Research Idea’ award. This award (up to 5000 euro) allows Laurine to execute a brilliant idea during her PhD within the frame of her research on cable bacteria. Laurine will use this to find out, on the level of genetics, ‘who’ exactly those interesting bacteria are …

We are looking forward to the results and congratulate Laurine with her brilliant idea!

Impactite, and shocked granite from IODP - ICDP core

PHD POSITIONS

The AMGC group at the Vrije Universiteit Brussel recruits PhD students to work on the IODP-ICDP core in the KT boundary Chicxulub crater.

In April 2016, IODP-ICDP drilled a core down to 1335 m in the 200 km in size Chicxulub crater,  offshore  Yucatan  (see  http://www.eso.ecord.org/expeditions/364/364.php).  In  the  Fall
2016, the recovered material was described and sampled at the IODP Bremen core repository. Samples from the KT boundary interval, impactites, and uplifted granitic basement are available at  the VUB.  Building  on  more  than  25  years  at  the  forefront  of  KT  research,  the  proposed doctoral  theses  are  financed  by  different  projects  focusing  on  the  study  of  the  material recovered by the IODP-ICDP drilling.  The goals are to  document the cratering process, peak-ring  formation  and  melt  production,  understand  ejecta  production  and  deposition, 

  1.  constrain the products injected into the atmosphere, and their effect on the mass extinction,
  2. test the proposed connection between Chixculub and Deccan trap volcanism (see Renne et al. 2015), 
  3.  learn  from  Chicxulub  to  understand  the  evolution  of  terrestrial  planets…  

All  new ideas are welcome, so are interaction with other AMGC members working on similar topics.

The PhD funding is for a duration of max. 4 years. Starting dates are flexible, preferentially Spring  -  Summer  2017. Applications  will  remain  open  until  all  positions  are  filled.  Enthusiastic and  motivated  scientists  are  encouraged  to  apply. The  PhD  salary  makes  it  possible  to  live comfortably in Brussels and includes benefits (transport, medical etc.).

Science comes to life
28/11/2016 - 16:00

'Dag van de Wetenschap' is all about bringing science to the people and AMGC is very proud to have been part of this. We wanted to show that science is hiding everywhere, even in places people don't always suspect. So we teamed up with our colleagues from archaeology and engineering to talk about archaeological science and palaeontology. Behind the organization is the interdisciplinary group ArCPIG, supported by AMGC, SKAR and SURF.

Similar impact on the moon
21/11/2016 - 15:00

The team’s new work has confirmed that the asteroid, which created the Chicxulub crater, hit the Earth’s surface with such a force that it pushed rocks, which at that time were ten kilometres beneath the surface, farther downwards and then outwards. These rocks then moved inwards again towards the impact zone and then up to the surface, before collapsing downwards and outwards again to form the peak ring. In total they moved an approximate total distance of 30 kilometres in a matter of a few minutes.

Dr. Matt Genge

Abstract: "Micrometeorites are extraterrestrial dust particles that survive atmospheric entry to be recovered from the Earth's surface. These particles are the fastest dust on Earth, experiencing velocities of more than 11 km/s. Combining observations of real micrometeorites with numerical models of atmospheric entry helps us understand their formation."

The talk will be held on Wednesday, 26 October, at 12:30, in Building D, Room 5.236. We look forward to seeing you there!
