Lower Paleozoic carbonate rocks of the Baird Mountains quadrangle, western Brooks Range, Alaska Lower Paleozoic carbonate rocks of the Baird Mountains quadrangle, western Brooks Range, Alaska

Lower Paleozoic carbonate rocks in the Baird Mountains quadrangle form a relatively thin, chiefly shallow-water succession that has been thrust-faulted and metamorphosed to blueschist and greenschist facies. Although this succession was thought to be mostly Devonian until recently, a large part of it is in fact pre-Silurian in age. Middle and Upper Cambrian rocks - the first confirmed in...

Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast

On nautical charts, we measured four island characteristics (area, length, width, shape...
