Autor: Anika Husen, Renat R. Almeev, François Holtz, Jürgen Koepke, Takashi Sano, Kurt Mengel

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 14, Iss 10, Pp 3908-3928 (2013)

We present the results of a petrological study of core samples from Tamu Massif (Site U1347), recovered during the Shatsky Rise Integrated Ocean Drilling Program (IODP) Expedition 324. The basaltic glasses from Site U1347 are evolved tholeiitic basal

ICDP Oman Drilling Project: varitextured gabbros from the dike–gabbro transition within drill core GT3A

Autor: Artur Engelhardt, Jürgen Koepke, Chao Zhang, Dieter Garbe-Schönberg, Ana Patrícia Jesus

Publikováno v: European journal of mineralogy : EJM 34 (2022)

The Oman ophiolite (Samail massif, Sultanate of Oman) is the largest sub-aerial exposure of oceanic lithosphere on Earth and provides the opportunity to study the accretion and alteration of oceanic lithosphere formed under fast-spreading conditions.

Accretion of fast-spreading oceanic crust: benefits from large-scale sampling in the Oman ophiolite in combination with cores drilled by the ICDP Oman Drilling Project

Autor: Jürgen Koepke, Dieter Garbe-Schönberg, Dominik Mock, Sven Merseburger

Based on a newly established profile through fast-spreading oceanic crust of the Oman ophiolite and on cores drilled within the ICDP Oman Drilling Project (OmanDP), we present here the results of 12 years research, focusing on the nature of the magma

A profile through fast-spreading oceanic crust in the Oman ophiolite: reference frame for the crustal drillings within the ICDP Oman Drilling Project

Autor: Jürgen Koepke, Dieter Garbe-Schönberg, Dominik Mock, Samuel Müller

The Oman Ophiolite is the largest and best-investigated piece of ancient oceanic lithosphere on our planet. This ophiolite was target of the Oman Drilling Project (OmanDP) within the frame of ICDP (International Continental Scientific Drilling Progra

A Reference Section Through Fast‐Spread Lower Oceanic Crust, Wadi Gideah, Samail Ophiolite (Sultanate of Oman): Trace Element Systematics and REE Crystallization Temperatures—Implications for Hybrid Crustal Accretion

Autor: Samuel Müller, Dieter Garbe‐Schönberg, Jürgen Koepke, Kaj Hoernle

Publikováno v: Journal of Geophysical Research: Solid Earth. 127

Oceanic gabbros are the most abundant rocks close to Earth’s surface. Here we present new data from a consistent profile through the paleocrust of the Samail ophiolite (Oman), which is thought to provide the best analogue for modern fast-spreading

Electron probe microanalysis of Fe2+/ΣFe ratios in calcic and sodic-calcic amphibole and biotite using the flank method

Autor: Jürgen Koepke, Lian-Xun Wang, Xue-Chun Zhang, Chao Zhang, Renat R. Almeev, Xin-Fu Zhao, Xiaoyan Li, Francois Holtz

Publikováno v: Chemical Geology. 509:152-162

We present an analytical approach to determine the Fe2+/ΣFe ratio in amphiboles and biotites using electron probe microanalysis (EPMA). The “flank method” applied in this study is based on the fact that FeL line spectra show different peak posit
