PETROLOGY, GEOCHEMISTRY, AND AGE OF EXTENSION IN THE LOST TRAIL PASS DIKE SWARM, SOUTHWEST MONTANA
The East Fork Dike Swarm (EFDS) at Lost Trail Pass (LTP) is one of many dike swarms that lie within the North American Cordillera, a region that has been transformed through the complex interactions between contemporaneous tectonics and magmatism. Determining the age of the EFDS at LTP, and the LTP …

Detektion eines mesozoischen Gangschwarmes in NW Namibia und Rekonstruktion regionaler Spannungszustände während der Südatlantiköffnung
… im namibianischen Henties Bay-Outjo Dike swarm (HOD) war zur Zeit der Unterkreide einem Rifting mit intensiver Platznahme von überwiegend mafischen Gängen unterworfen. Geochemische Signaturen weisen die Gänge als erodierte Förderkanäle der Etendeka Plateaubasalte aus. Durch den …

Geochemistry of mafic dikes from the Coastal New England magmatic province in southeast Maine, USA and Nova Scotia, Canada
Mid-Late Triassic-age alkali-basalt dikes were emplaced along the coast of New England between 240-200 Ma. Known as the Coastal New England (CNE) magmatic province, this dike swarm is the immediate magmatic predecessor to the formation of the Central Atlantic Magmatic Province large igneous …

Structure and regional tectonic setting across the Atlantic Coastal Plain of northeastern Virginia as interpreted from reflection seismic data
… appears to be intruded by moderately dipping dikes that were fed by the sill. The occurrence of basaltic material within the basin is confirmed by well log data. Probably the most important result of this study is the tectonic implications of prominent, arcuate potential field anomalies and …
