Microstructures associated with the Sottunga-Jurmo shear zone and their implications for the 1.83-1.79 Ga tectonic development of SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2010 This petrographic study of rock samples from the area of a large-scale shear zone, the Sottung-Jurmo shear zone, in SW Finland, illuminates the thermal development of and strain distribution within the rocks during the last development stages of the ...

Friction of Shear-Fracture Zones [PDF]
Physical Review Letters, 2017 A shear fracture of brittle solids under compression undergoes a substantial evolution from the initial microcracking to a fully formed powder-filled shear zone. Experiments covering the entire process are relatively easy to conduct, but they are very difficult to investigate in detail. Numerically, the large strain limit has remained a challenge.

Structural control on gold mineralization in the Satulinmäki and Riukka prospects, Häme Schist Belt, southern Finland [PDF]
Bulletin of the Geological Society of Finland, 2007 The Satulinmäki and Riukka prospects located in the Häme Schist Belt in southern Finland are dominated by mafic and intermediate to felsic metavolcanic rocks of the Forssa Group formed in a continental arc setting.

Core Precession and Global Modes in Granular Bulk Flow [PDF]
, 2005 A transition from local to global shear zones is reported for granular flows in a modified Couette cell. The experimental geometry is a slowly rotating drum which has a stationary disc of radius R_s fixed at its bottom.

Effect of Spatial Variations in Floodplain Vegetation on Bed Shear Stress Distribution [PDF]
长江科学院院报[Objective] This study aims to investigate the effects of different vegetation arrangements (parallel and staggered) in the junction zone between channel and floodplain in urban rivers on the spatial distribution of bed shear stress, and to reveal how ...

Shear zones in granular media: 3D Contact Dynamics simulation [PDF]
, 2007 Shear zone formation is investigated in slow 3D shear flows. We simulate the linear version of the split-bottom shear cell. It is shown that the same type of wide shear zones is achieved in the presence as well as in the absence of gravity.

Structural features and emplacement of the late Svecofennian Perniö granite sheet in southern Finland [PDF]
Bulletin of the Geological Society of Finland, 1996 The 1840-1830 Ma old Perniö granite occupies the southern margin of the Sauvo-Perniö granite area located in the western part of the late Svecofennian granite-migmatite zone in southern Finland.

Геодинамика и тектонофизика, 2015 Introduction. In this publication, shear zones, being traditional objects of tectonophysical studies, are considered in terms of their strain states. This approach differs from a commonly applied one when shear zones are studied with consideration of ...
