GSA 2016 - Live Report day 1
Last Updated: 26th Sep 2016By Jolyon Ralph
This is a LIVE report, keep this page loaded for live updates - new images will appear as they are added.
I'm back in Denver for the Geological Society of America's major annual conference. I'll be reporting on the mineralogically-related presentations here. Right now I'm waiting for the first presentation on Precambrian Evolution and Mineral resources of the Mid-continent rift. And waiting here with me is mindat.org regular Paul Brandes.
The event guide. This place is big.
I'll show some of the sessions on today and drop into a few.
Alkaline rocks
Presentation on new geochronologica constraints on the formation and hydrothermal enrichment of the Bokan mountain peralkaline complex
Dikes crossing the aegirie granite boundary
Dotson zone dike appearance
Replacements of what was probably an amphibole
Hydrothermal zircon used gorvgeochronolgy - which apparently causes big problems
Geochronology sample locations.
