Cal Poly Geology

Geology and Geophysics at Cal Poly San Luis Obispo.

GEOL 420 class collecting 2D electrical resistivity tomography data over a landslide in Poly Canyon, and examining the contact between the Toro Formation and the Franciscan Melange where it nucleated.

It's been a good run - several years - since the Field Geophysics class (GEOL 420) broke a cable in the field (luckily not too expensive). Not sure I can solder this one back together 🤔We had enough swings to get a good stack - but three channels were flaky. @CalPoly

Cal Poly Geology is collecting electrical resistivity data (with the mighty SuperStingR8) to characterize paleochannels in Morro Bay, CA, for a groundwater injection/recharge project.

@WyGeoSurvey Hello WyGeoSurvey,
The link to the arcgis story site about this post does not work - we were wondering if it is still possible to access it some other way? Thank you.

Setting up a 3D electrical resistivity survey over a landslide in Poly Canyon, and over an adjacent contact with Toro formation and Franciscan melange - will be a guide for interpreting the data. The local Cal Poly cows were quite interested, too!!

First seismic refraction data in GEOL 420 Applied Geophys class. Excellent data (except anomaly in the 1st arrival at geophone 2). Note - traces plotted against geophone number rather than offset here. But slope break easily seen. Geologic target is a shallow water table.

GEOL 420 Field Geophysics class performing a seismic refraction survey over an alluvial aquifer (The "Chorro Creek Dog Leg" site near the Cal Poly SLO campus). Going for a critical refraction from bedrock (and anything in between!). Nice looking data (but two funky geophones).

@AZGeology Is this from a map in the AZGS library?

@AdvGeosciences These are really useful to highlight in my field geophysics class.

Collecting reconnaissance seismic refraction tomography data at a hard-rock aquifer study site of weathered granite in the Salinian Block along the Rinconada Fault (Paso Robles, CA area).

GEOL 241 (physical geology lab) students in poly canyon determining if they have yet gone enough up section to go from Toro Formation to Rincon Shale. Beautiful day and setting 😃

GEOL 420 Field Geophysics class beginning seismic refraction surveying this week. With midterms etc., it's a good time to be swinging a sledgehammer

GEOL 420 class collecting electrical resistivity (w/SuperStingR8) data over the Rinconada Fault, separating crushed Salinian Block granites from shale and sandstone units in west Paso Robles.

2D Electrical Resistivity survey this morning with GEOL 420 Applied Geophysics class. Trying to figure out structure of a local thin alluvial aquifer, especially the bedrock - the variable outcrops make it ambiguous for now ... beautiful morning in San Luis Obispo 👍😀

@USGSwaterCA How did the data turn out?

[Cal Poly Geology @CalPolyGeology]

Another electrical resistivity line (1,100 meters) at Cal Poly's Bartleson Ranch. Slowly piecing together the hydrogeology ... more to come.

[Cal Poly Geology @CalPolyGeology]

@IRIS_EPO A great resource. We use them in our seismology class a lot - thank you.

GEOL 305 at Waterman Hills Detachment Fault (near Barstow, CA) we found the domino style normal faults in the hanging wall Fig. 4B in Glazner et al., 2002 Cenozoic Evolution of the Mojave Block in southern California (GSA Memoir 195, p 19-41). https://t.co/e3dHLpteZq
