The role of eclogite in the mantle heterogeneity at Cape Verde
The Cape Verde hotspot, like many other Ocean Island Basalt provinces, demonstrates isotopic heterogeneity on a 100–200 km scale. The heterogeneity is represented by the appearance of an EM1-like component at...

Sub-volcanic infiltration and syn-eruptive quenching of liquids in cumulate wall-rocks: the example of the gabbroic nodules of Stromboli (Aeolian Islands, Italy)
¶Fine- to coarse-grained plutonic nodules within the Petrazza pyroclastics (Paleo-Stromboli I period) consist of gabbroic rocks with variable amounts of interstitial material. They are characterised by cumulat...

Replenishment episodes and crustal assimilation in the development of an early Tertiary magma chamber, East Greenland: evidence from layered cumulates of the Kælvegletscher ultramafic complex, Kangerlussuaq
From the early Tertiary Kælvegletscher ultramafic cumulate complex, emplaced into the Archaean basement on the west side of the Kangerlussuaq Fjord, East Greenland, we present geochemical and isotopic data fr...

Origin of high-silica liquids at Stromboli volcano (Aeolian Islands, Italy) inferred from crustal xenoliths
High-silica igneous xenoliths (granophyre and obsidian fragments with SiO2 ca. 75 wt.%) and high-silica glass (SiO2 between ca. 64 and 75 wt.%) within glass-bearing tonalitic and dioritic xenoliths have been dis...

Strontium-Isotope Studies Of Chloride-Contaminated Groundwater, Denmark
Saline groundwater has three principal origins in Denmark: 1) Seawater infiltration into nearcoastal aquifers, 2) saline formation water in aquifers of marine sedimentary origin, and 3) intrusion of brines fro...
