Field Trips

Southwest Santa Cruz Island: Intraplate Motion and Deformation

Mobirise

Field Trip Leader

Jim Boles of U.C. Santa Barbara

Participants in this one-day field trip will travel by boat from Ventura Harbor to Prisoner’s Harbor on the island. Then, travelling by jeeps and trucks along the spine of Santa Cruz Island, we will drop down to the southwestern coast of the island, an area not open to the public. Outcrops include the oldest rocks on the island, the Santa Cruz Island Schist,  as well as a diverse sequence of Paleocene to Miocene sedimentary rocks exposed in arroyos and beach cliffs. These rocks include spectacular fossil beds, conglomerate and breccia that reveal intraplate motion and deformation, and volcaniclastic “Monterey-like” sequences with an unknown source. We will also visit major structural features such as uplifted marine terraces, offset stream drainages, and the famous Santa Cruz Island strike-slip fault that juxtaposes these rocks with the Santa Cruz Island volcanics.

Montecito and Santa Barbara Debris Flows

Mobirise

Field Trip Leader

Ed Keller of U.C. Santa Barbara

Field trip stops are:
  1. Montecito Debris Flow of 2018 at and upstream of a debris basin in Montecito
  2. Several Pleistocene debris flows on the beach at Montecito Shores near the Biltmore Hotel, ~2000 year old earthquake marine terrace and Chumash Site on top of the earthquake terrace
  3. Faulted and folded < 100 ka debris flow deposits and Holocene sediments that are folded and faulted in a sea cliff exposure at Summerland Beach East
  4. Very large (several times larger than Montecito Debris Flow of 2018 ), ~1ka old debris flow at Rocky Nook Park in Santa Barbara
  5. ~100 ka debris flow folded over the Mission Ridge Anticline. Discuss at lunch the role of active tectonics in influencing the exposure of people and property to the debris flow hazard in Montecito and Santa Barbara

Petroleum Migration in an Active Petroleum System, Santa Barbara Basin, California USA

Marc Kamerling, Consultant

The northern coast of the Santa Barbara Channel is a superb location to observe a petroleum system in action. The primary source rock of southern and central California – the Miocene Monterey Formation – crops out along the coast while just a few kilometers offshore,it is currently generating hydrocarbons. This results in active migration culminating in over 35 known oil and gas fields, exhumed reservoirs, and abundant natural seeps along the coast and offshore. Thus, most components and many processes of an active petroleum system can be observed along the Santa Barbara coast. This field trip will visit 3 locations where active migration can be observed following different kinds of pathways.

Sedimentation, Tectonics, and Petroleum Systems of the Eastern Ventura Basin

Mobirise

Field Trip Co-Leader

Greg Gordon of Aera Energy

Mobirise

Field Trip Co-Leader

Stuart Gordon of California Resources Corporation (ret.)

The petroliferous Eastern Ventura basin (EVB) formed as a borderland-style, fault-bounded deepwater trough in the middle Miocene, and it contains excellent outcrops of turbidite systems such as the Modelo and Towsley Formations. The object of this field trip is to view 3-4 outcrop exposures and discuss the stratigraphic architecture, distribution of lithofacies associations, and interpreted evolution of EVB’s Mio-Pliocene depositional systems. We will focus on implications for reservoir quality and geometries, as well as structure-stratigraphy interactions, hydrocarbon generation and migration, and evolution of this deepwater basin. This field trip will also highlight some of the EVB’s fascinating oilfield history, which dates back to the 1880’s.

The Ridge Basin: Transition from Marine to Non-marine Sedimentation in a Basin-Filling Cycle

Mobirise

Field Trip Leader

Dan Schwartz of Daniel E Schwartz, LLC

The unique interplay between tectonics and sedimentation in Ridge Basin presents an extraordinary opportunity to examine depositional environments of deep- water turbidites, shallow marine, delta plain, and fluvial/alluvial deposits. This region provides visible examples of geological processes in an active tectonic setting. This trip will visit classic outcrops of the Ridge Basin en route from Oxnard to Bakersfield. Participants will be responsible for their own transportation and meals.

Structural Transect along Highways 33 & 166: Petroleum Geology of the Ventura and Cuyama Basins, California

Mobirise

Field Trip Leader

Thom Davis of Thomas L. Davis

Description: A one-day trip from the Ventura anticline oil field, north along Hwy 33 across the western Transverse Ranges fold and thrust belt, and then through the Cuyama Basin and oil fields along Hwy 166. Emphasis will be on the structural geology, oil field traps, and petroleum systems. Trip is led by Thomas L. Davis from the Geologic Maps Foundation
