In many areas, for example 1 km south of the Seattle fault zone on line PS-2, a reflection from the Tertiary-Quaternary angular unconformity is observed. At the south end of both lines, strong ...

When I took this photograph I didn’t have any specific knowledge of this geology because we […] This week's Friday Field Foto is from an area just west of Death Valley called Darwin Canyon.

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 ...

The mystery of the Great Unconformity is inherently tied to two of geology’s other great enigmas: the rise and fall of Snowball Earth and the sudden emergence of complex life in the Ediacaran and ...

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 ...
