In February 2017, a team from UU went to the Andaman Island to study the subduction history. I was one of the four fortunate. Here is a summary of this amazing field trip. Let's start with the geology of the Andaman islands.They lie in the Bay of Bengal, southeast of India mainland and are situated very close of the present-day Sunda-Sumatra subduction zonethat is well known for the 2004 devastating earthquake. The target of our fieldwork was to sample the ophiolite (Cretaceous) and the forearc (Paleogene) for paleomagnetic and petrological work.
The team was the following:
- Douwe van Hinsbergen
- Pinaki Bandyopadhyay
- Eldert Advokaat
- Debaditya Bandyopadhyay
- Yael Engbers
- Loes van Unnik Hoorn
- and myself, Alexis Plunder
This trip was the last one of the SINK project funded by the ERC and granted to D. van Hinsbergen
