This study represents the first positive demonstration that such a process occurs naturally. The Ordovician paleomagnetic pole position for North...

Salic dykes and minor faults cutting the stock represent the closing phases of orogenic activity in this area.Structural, petrographie, and chemical data indicate that the stock is of magmatic origin. Differential assimilation of the host conglomerate and shales may have locally modified...

...N. C. Wardlaw; D. W. Watson Abstract The Prairie Evaporite formation, or First Salt, of the Elk Point area contains three types of halite: chevron, clear, and brown. The chevron halite is thought to be primary and to have grown upwards from the Devonian sea floor. The origin of the clear and brown...
