The angular unconformities also provide tectonic constraints for the latest and ongoing tectonic activity in the Quaternary. This tectonic movement begins at around 80 ka BP and causes two different ...

The contact between the sediments and the tuff is an angular unconformity — a boundary where one rock unit cuts across the layering of another. This indicates a period of erosion and a time when ...

One of the things I love to do on this blog is share photographs of geology I’ve taken while doing field work, attending field trips/conferences, or simply traveling. I started this series of ...

He spoke on gradual change of a sharp angular unconformity in Painganga valley into a graded unconformity as we move towards the dip direction. Explaining the different types of shear and strain ...

It was first described in 1788 by James Hutton, the ‘father of geology’, as an example of an angular unconformity – a junction between two sets of rocks of different ages.
