We have been busy! Obviously, it's still a work in progress, but can not be prouder of how this project is coming along. Lots of new data types to be released in the coming months (e.g. U-Th-Pb; Ar-Ar; Hf isotopes).

@sydney_ev Just felt something in Canberra too

@waon_v2 Amazing!!!
May I ask? Any green rocks in the drillcores? 😋

Deformed clinopyroxenite-dunite layers, Cabo Ortegal Massif.
単斜輝岩とダナイトの層状構造がぐにゃっと曲がってる。って、やはり、曲がってるかどうかは、目印がないと気づかないのかもしれない。

🤩Excited to lead the #lherzolite2024 field trip to the mantle section of the Cabo Ortegal Complex in just a month! Here's a teaser of one the outcrops we'll see, Galician weather allowing... ⛰️🌦️

Finally home after an incredible/privileged expedition on the RV Yokosuka and the DSV しんかい6500. Most incredible experience + successful sampling 🌋 #peridotitexenoliths from the oceanic lithosphere

@Tetraheedra As fresh as they get! Continental tertiary basalts wouldn't do better. Would be hard to tell they are from the oceanic lithosphere if it wasn't for the fact that we collected them ourselves. Definitely looking forward to studying them in depth (pun intended)

6/20から本日まで、東北沖での調査航海に参加してきました。自分にとっては8年ぶりくらいの #しんかい6500 を用いた調査で、色々と勉強をさせていただきました。
