A novel strip-sampling technique has been applied to the 500-m gabbroic section drilled at site 735 during Leg 118. Twenty-two continuous strips of 1.1- to 4.5-m length were cut longitudinally from the core, allowing for a more representative samplin

Petrology of basaltic glasses from the TAG Segment: Implications for a deep hydrothermal heat source

Autor: Peter S Meyer, Wilfred B. Bryan

Publikováno v: Geophysical Research Letters. 23:3435-3438

The trace element composition of basaltic glasses from the TAG segment of the MAR indicate that magmas erupted on the surface are derived from multiple primary magmas with Ce/Sm ratios varying from 2.2 to 3.9. In the pseudoquaternary system olivine-p

Evolution of Icelandic central volcanoes: evidence from the Austurhorn intrusion, southeastern Iceland

Autor: Frederick A. Frey, Peter S. Meyer, Tanya Furman

Publikováno v: Bulletin of Volcanology. 55:45-62

The Austurhorn intrusive complex in southeastern Iceland represents an exhumed Tertiary central volcano. The geometry of the intrusion and geochemistry of the mafic and felsic rocks indicate Austurhorn was a volcanic center analogous to Eyjafjallajok

The 1783 Lakagigar eruption in Iceland: geochemistry, CO2 and sulfur degassing

Autor: Nicole Métrich, Joseph D. Devine, Haraldur Sigurdsson, Peter S. Meyer

Publikováno v: Contributions to Mineralogy and Petrology. 107:435-447

About 12.3 km3 of basaltic magma were erupted from the Lakagigar fissure in Iceland in 1783, which may have been derived from the high-level reservoir of Grimsvotn central volcano, by lateral flow within the rifted crust. We have studied the petrolog
