Fluid Inclusion Analysis Of Halite: A Snapshot Of The Cambrian Explosion, Amy R.A. Lefebvre

Undergraduate Student Research Internships Conference

This research focused on obtaining a brief overview of information preserved within evaporite samples formed during the Early Cambrian. With the help of halite screening methods, fluid and gas analysis, through a micro thermometer and mass spectrometer, respectively, as well as trace element analysis conducted by Act Labs, results reflecting Earth's climate over 500 million years ago were obtained. These indicated the approximate weather conditions, and atmospheric composition, during this time period, within an intracontinental dessert location. Specifically, these results reflects a global warming period, with daily variations. Although much more research is needed in order to validate this summer's …
