Drillcore GT1 of the ICDP Oman Drilling Project: insights into magmatic processes beneath fast-spreading mid-ocean ridges

Dominik Mock, Benoit Ildefonse, Dieter Garbe-Schönberg, Samuel Müller, David Axford-Neave, Jürgen Koepke & Diverse Science Team
The Samail ophiolite in Oman provides an ideal field laboratory for investigating the processes taking place beneath fast-spreading mid-ocean ridges (MORs). Drill site GT1, which was sampled by the Oman Drilling Project in the frame of the International Continental Scientific Drilling Program (ICDP), is located in Wadi Gideah (Wadi Tayin massif). Here, a reference profile through the entire Oman paleocrust was established [1] such that GT1 can be embedded into the surface profile. The core...

The ICDP Oman Drilling Project – Implications from drill core GT1 on magmatic processes beneath fast-spreading mid-ocean ridges

A key aim of the ICDP Oman Drilling Project is to constrain magmatic processes beneath fast-spreading mid-ocean ridges. Several drill cores from the Samail ophiolite (Oman), which is regarded as the best-preserved piece of ancient oceanic lithosphere on land, were obtained. Drill core GT1 covers about 400 m from the layered gabbro section between ~1200 and 800 m above the mantle transition zone (maM). The vast majority of the samples recovered are (olivine-) gabbros with...
