Borates such as colemanite are thought by some to have stabilized ribose, an essential component of ribonucleic acid and critical for the self-assembly of prebiotic organic compounds to constitute life; others have proposed that ribose was stabilized by borate in solution.

Boron isotopes provide insight on the processes responsible for the creation of continental crust, and act as a proxy for paleoclimate.

However, the term is used more specifically for all naturally occurring radioactive materials where human activities have increased the potential for exposure compared with the unaltered situation.

Concentrations of actual radionuclides may or may not have been increased; if they have, the term Technologically-Enhanced (TENORM) may be used.

Long-lived radioactive elements such as uranium, thorium and potassium and any of their decay products, such as radium and radon are examples of NORM.

I was able to travel to remote helicopter access locations in the Coast Mountains of British Columbia, the Swiss Alps, Arizona, Himalaya, southern Yukon, and Alaska to participate in research projects, workshops, and conferences. in geology at Carleton University in Ottawa (2005).

Currently, in my positions as the Outreach Geologist for the Yukon Geological Survey, I am able to share my passion for the Earth Sciences with all sorts of people and I really enjoy my job. I did a Bachelor's degree at University of Saskatchewan in geology (1998). I currently work in Yellowknife, NT, as a geologist at a territorial government office called Northwest Territories Geoscience Office.

Moreover, the maximum EISC and its isostatic footprint had a profound impact on the proglacial hydrological network, forming the and drained the present day Vistula, Elbe, Rhine and Thames rivers through the Seine Estuary. 14.6 ka BP, two major proglacial lakes formed in the Baltic and White seas, buffering meltwater pulses from eastern Fennoscandia through to the Younger Dryas when these massive proglacial freshwater lakes flooded into the North Atlantic Ocean.
