Rockin’ Pop-Up: Chemical Sedimentary Rocks

This week the Geology Gents are rounding out our recent discussions about the three main rock types (igneous, sedimentary, and metamorphic) by digging a little deeper into sedimentary rocks. This week we’ll explore how sedimentary rocks can be further impacted by their environments, resulting in the phenomenon of chemical sedimentary rocks. Some well known examples are geodes and opals.

About the series: Join the Geology Gents, Gavin and Graham, for weekly conversations about rocks live on Facebook. Each week 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 on Facebook or by emailing events@santacruzmuseum.org, or during the program live on Facebook. Feel free to include pictures of rocks you’d like identified! Pro-tip: the better the picture, the better the ID.
