The shear strength of soils is influenced by various geological parameters. Following the shear strength study of Norwegian tills by Opsal (2017), this study presents test results of a selection of such parameters, i.e., particle size distribution, particle shape, and the mineralogical composition, of 33 till samples (fractions

The Duncan Canal shear zone, central southeastern Alaska, disrupts and penetratively deforms Devonian, Pennsylvanian, and Upper Triassic strata of the lexander terrane. The deformation is interpreted to have occurred within a regime of right-lateral shear during Early or Middle Jurassic time.

Deep (+500-m) shear wave velocity ( V S) profiles were developed at 14 sites throughout Christchurch, New Zealand, using a combination of active-and passive-source surface wave testing. The geology of Christchurch is complex and presents several challenges for surface wave testing.

Contributions from Bridgman’s high‐pressure laboratory at Harvard are always of interest. In the present article he discusses flow, and the shearing stresses necessary to produce flow under high pressure for a wide variety of substances. Rigidity, or the resistance to shearing stress, is one of the fundamental constants of the seismologist, and ...

The Etam shear zone is the NNE-SSE to NE-SW trending fault zone with coexistence of a sinistral shearing mylonitic corridor and a brecciated quartz vein. The mylonitic zone is evidence of progressive deformation. Primary minerals include Qtz1 + Kfs1 + Pl1 + Bt1.

Many Early Proterozoic volcanogenic sequences in southern Finland and adjacent Sweden have long been interpreted as bedded tuffs and “tuffites” (i.e., epiclastic volcanic sediments), and commonly have been called leptites and halleflintas. While definitions of these unfamiliar terms vary, even in Fennoscandinavia, leptites and halleflintas can be ...
