Interpreting fold data on stereonets

How to interpret fold data on a stereonet by Dr Jacqui Houghton. This is part five of a series of videos used on the first year Structural Geology course at the University of Leeds.

These videos help alot. Hours of reading trying to figure it out got simplified in 2 minutes

[@TheStonedGeologist3]

have my structural final tomorrow lol wish me luck

[@HorseLoverNoOne]

If I pass my exam I 100% ow it to you.

[@dapilki]

This video helped me on my coursework for my degree and for revision for a continental deformation module thank you so much!!!

[@TheMattwasherein1992]

sick!!!!! got my geo exam on thursday!! helps a lot!

[@ali4games10]

Final exam in 40 mintues this helped me tremendously!

[@seyeruoynepotsuj]

This is excellent revision! Thanks for uploading these! :)

[@stephenoni2019]

thank you for this, it would be nice to have all the planes you used to plot those poles, it's just easier to follow along that way...

[@marciliorocha3212]

Great video. Thanks for sharing it with us.

[@skacyd]

you're so awesome!! Thank you so much for this!!

[@okekolade2349]

Thanks ,This was really helpful!

[@NightR4nger]

Clear and concise. Thanks for your help.

[@seyeruoynepotsuj]

How come I can spend three hours in class not understanding this and then watch a three minute video and get it perfectly!

[@NLuong604]

super useful video! thank you!!!! i finally understand how to do my assignment

[@augustusevelyn2702]

thank you thank you!!!! Been trying to figure out how to get the axial plane orientation

[@po132006]

thank you for all your videos!

[@aniruddhadas5526]

Thanks a lot,it really helpful

[@prakashkumarsingh95]

Can I use the technique for finding axial plane of an asymmetrical fold?

[@staceyrice9536]

How are you orienting the fold axis to determine the plunge? I see that you're bringing it to the equator, but should each of the ends be on 90 and 270? How are you setting that up?

[@deadsick95]

Are these poles to a plane? As in they are in the opposite quadrant of the plane?

[@memer2694]

Thanks for this!

[@umangatang]

nah man, note she plots a great circle which is a planar feature. If you imagine the centre point between all the poles to be the hinge of the fold (point between two limbs), the hinge is fixed to the axis - hence you connect the two. imagine you have two folds made of cake. If you cut it at the highest point (the hinge point), the blade of the knife will form an axial plane - a vertical plane separating the two limbs

great vid!

[@ashleypeay3500]

how do you know to count 90 to the right to find the fold axis and not 90 left when the video is at 3.34 minutes

[@ryanbunge3213]

Ashley Peay Because there isn't enough space to count to the left. Only one side will have room to count 90 degrees unless your great circle is in the very middle.

[@guacgarcon8573]

Why did you use 90 for the pole to the best fit line?

[@alexmilneskarzenski4231]

the pole is always 90 degrees perpendicular from the plane on the East-West line. Your plane is like the equator relative to the pole. I'm just a student but I'm 99.99% sure that's what it is.

[@PayneC]

Hello Dr. Houghton. I really enjoy your video. I'm curious, though, what do the poles that you draw the best fit line to represent, in regards to folds?

[@vietvu6751]

thank you so much

Good for study to basic
