The tectonometamorphic evolution of the Greater Himalayan sequence as exposed in central Nepal and adjacent south-central Tibet
Understanding the development of the Himalaya is critical to elucidating continental collisional processes. The Greater Himalayan sequence (GHS), the exhumed mid-crust of the Himalayan orogen, records the tectonometamorphic ...
The characterization, persistence, and bioaccessibility of roaster-derived arsenic in surface soils at Giant Mine, Yellowknife, NT
Approximately 20,000 tonnes of arsenic (As)-bearing emissions from roasting arsenopyrite ore were aerially released from 1949-1999 at Giant Mine, located outside Yellowknife, NT. As part of the process used to free ...
Origin and Significance of Middle Ordovician and Mississippian Calcarenites
Calcarenites are common throughout geologic history, but the range of depositional settings and conditions under which they form is poorly constrained. This study compares physically structured calcarenites in the Mississippian ...
Morphological and behavioural evolution through the Ediacaran and basal Cambrian of the Mackenzie Mountains, NW Canada
The Mackenzie Mountains of NW Canada contains a superb record of biotic evolution through the late Ediacaran-early Cambrian that is ideal for studying the biological, ecological, behavioural, and environmental innovations ...
