SCGS Geology Hike
Saturday, June 6 at 8:30 AM
South Coast Geological Society invites you to attend a Geology Hike along with Los Angeles Basin Geological Society (LABGS), led by Dr. Rick Behl of California State University-Long Beach!
Rick will lead an informal geology field trip/beach walk/coastal scramble. We will examine the complexly folded Monterey Formation between Little CDM Beach and Crystal Cove State Beach to try to discern synsedimentary from tectonic deformation.
The meeting is coordinated with low tide and will involve hiking/scrambling over wet outcrops and tidepools, so adequate hiking footwear is required.
Registration is limited to 20! To view more information and register by June 5, click the Eventbrite link below!
SCGS June Meeting with SDAG
Wednesday, June 10 at 6:00 PM
South Coast Geological Society invites you to attend our June 2026 meeting and lecture, co-hosted with San Diego Association of Geologists (SDAG)! Dr. Kate Metcalf, Assistant Professor in the Department of Geological Sciences at California State University, Fullerton (CSUF), will present her lecture titled: Something Old, Something New: Revisiting Permian to Jurassic tectonics in the Klamath Mountains, Northern California.
Please register by June 3 using the Eventbrite link below.
Abstract:
The Klamath Mountains straddle the California-Oregon border and are an amalgamation of accreted terranes. Despite the Klamath Mountains being the birthplace of the term “tectonostratigraphic terrane,” the ages, correlations, and tectonic settings of many Klamath terranes are still debated. One of the most enigmatic terranes is the Rattlesnake Creek terrane (RCT), a mélange of metamorphosed sedimentary and igneous blocks with a volcanic and sedimentary sequence deposited on top. Recent work shows that the overlying RCT cover sequence has a North American provenance but formed after accretion to the continental margin, so it is unclear if the basement mélange formed proximal or distal to North America. My research group conducted field mapping, petrography, and zircon geochronology. Our results show that the southernmost RCT preserves both Early Jurassic and Middle-Late Jurassic cover sequence deposits and records continental clasts and 33% pre-Mesozoic zircons at ~201 Ma. Rather than forming in a distance oceanic arc, the RCT likely formed at an east-dipping subduction zone proximal to North America.
