IN a previous account (Brown, ~967) of the granitic sheets and veins in the Loch Coire migmatite complex, a metasomatic origin was postulated. This has now been confirmed by new analyses. Read (I93I) described the Loch Coire complex as made of three zones; one of unmigmatized meta-sediments, one of granitic veins and one of 'injection' or migmatite. The sheets and veins of granite (sensu lato),...

Groundwater exploitation requires better understanding of the resource availability and quality/vulnerability. Geophysical techniques, pumping test, hydraulic measurement, borehole logging quality test analysis have been used in Ibulesoro, southwestern Nigeria, to hydrogeological system terms groundwater availability, aquifer delineation, evaluate physico-chemical biological contents. The study...

Eclogites hosted in sillimanite-bearing migmatites the Montagne Noire dome (French Massif Central) have an oceanic protolith and recorded a prograde P–T path from ~19.5 kbar, 700°C to pressure peak at ~21 750°C (pseudosection modelling), suggesting metamorphism subduction setting. Subsequent exhumation low-P high-T (LP–HT) conditions (~6 730°C) is constrained by equilibration of embedding migma...

An introduction to the Bouguer anomaly map of Finland is presented. Anomaly sources from surface to upper mantle are discussed both qualitatively and quantitatively. Related density variations are reviewed. The article is based on gravity data from the Finnish Geodetic Institute supplemented by petrophysical and gravity data from the Geological Survey of Finland. The Finnish Geodetic Institute ...
