About the Series: Join the Geology Gents, Gavin and Graham, for monthly conversations about rocks live on Facebook. Each month we’ll explore a different geologic topic, from Santa Cruz formations to tips for being a more effective rockhound. Graham Edwards and Gavin Piccione are PhD candidates in geochronology with the Department of Earth and Planetary Sciences at UC Santa Cruz.
Submit your questions ahead of time by emailing firstname.lastname@example.org and feel free to include pictures of rocks you’d like identified! Pro-tip: the better the picture, the better the ID.
