This cross-section of the Southern Uplands shows the rock units and graptolite zones identified by Charles Lapworth, allowing him to unravel the region's complex geological history!

When Thomas Sopwith became involved in resource geology, he knew that an understanding was essential for estimating coal reserves, so produced models where layers were depicted using different types of wood to help miners!

This lantern slide is from our structural geology collections and shows a labelled sketch of a normal fault. A real life normal fault is along the East African Rift Valley where there is a developing divergent plate boundary.

This lantern slide shows a diagram of a reverse fault. In a reverse fault, the hanging wall (block above the fault) moves upwards relative to the foot wall (block below the fault). Do you know any real-life examples of a reverse fault?

We have a new theme for our Friday posts - #FaultFriday! This lantern slide shows a young fault scarp in eastern California. A fault scarp is an offset in the ground caused by an earthquake, that occurs on a pre-existing fault.

Happy #FaultFriday! GCG member B.T. recently made the rainy trek to see the two (terrestrial) ends of the XEOLXELEK-Elk Lake fault in BC, Canada, newly discovered by @NHarrichhausen et al last December. You can read their article here: https://t.co/CNMA4ejsV2
Magnificent transition from Ljubljana Basin to Kamnik-Savinja Alps, Slovenia.
That's where the Sava Fault is.

Trace of the strike-slip Raša Fault is drawing a sharp lineament, visible even in forested area of SW Slovenia

Overthinking is when you see a fault rupture map in your hand lines #FaultFriday

On 16 Dec. 1811, 211 yrs ago #OTD, the New Madrid Seismic Zone sprang to life at ~2:15am local time, an earthquake now thought to have been on the southern limb of the zone, the Axial fault. No surface deformation from this event was documented, at the time or since

Revisiting classical outcrops with 4th year undergrad students looking for compressional structures at the Southern Pyrenean Foreland. Five stars outcrops during the day and discussions with digital outcrops after fieldwork! @DeptDto @geologiaub #faultfriday
It’s #FoldFriday & #FaultFriday - show us your favourite #ScottishGeology structures 🎉
Here’s one from the west coast of Shetland - a gorgeous exposure of Devonian Old Red Sandstone belonging to the Melby Formation, you can see gently folded sediments cut by a fault!
Happy #FieldworkFriday ! Salt was nice but look at theses amazing fault planes in sandstones! #EasternCarpathians #FaultFriday
These kind of data are mesmerizing and tell us a lot about surface faulting, but raise the question on how comparable are modern data with those acquired only 10 or 20 years ago. #FaultFriday
The latest drone DEMs showing the surface ruptures of the M6.8 Guanshan-Chihshang earthquake in Taiwan. (Credits to the Central Geological Survey)
This #FaultFriday some photos of the Outer Hebrides Fault Zone, taken on a walk along a local beach south of Tolsta Head, #IsleofLewis
Chewed up and retrogressed #Lewisian gneisses and granitoids 😢 experienced both ductile and brittle deformation over a long period of time.
#FieldworkFriday @EmaScaramuzzo leading a #mapping effort in the Monviso (NW Italy) area. #FaultFriday #FridayFold
Current status of a project for updating equations of the likelihood of surface faulting #FaultFriday
BTW, if someone in the Twitterverse has the Wells&Coppersmith 1993 dataset and is willing to share, they’re my heroes!
