Cosmogenic Nuclides

Cosmogenic nuclides (especially Be-10 and Al-26 in quartz) offer numerous opportunities to study Earth surface processes. These nuclides are produced in the Earth's atmosphere and surface by interaction between high-energy cosmic rays (originated in supernova explosions) and atoms on Earth. 
I use these nuclides as tools to calculate rates of erosion of the Earth's surface in the past and present and dates of fluvial deposits and Earth surfaces (rocks, terraces, etc). 
Brazil is in its infancy as far as using cosmogenic nuclides to understand its landscapes so there are many opportunities and interesting problems to seek answers to!
