Wind shears in the meteor zone
Planetary and Space Science, 1968Abstract Records of meteor drifts obtained during the I.Q.S.Y. with the radio-meteor technique have been used to resolve wind shears in the 80–100-km region of the upper atmosphere. Some theoretical aspects relevant to the technique of observation are being dealt with and comparison is made with wind shear data obtained by different methods. Two main

Abstract Although many ductile shear zones are supposed to have developed by approximately simple shear flow, some must have formed under different conditions. A few types of such ‘non-simple shear zones’ have been proposed in the literature such as transpression-, transtension- and stretching-shear zones. This paper presents a full three-dimensional

Graphite and Shear Zone Evolution
2016Graphite is one of the most distinctive features of the Macraes deposit. Graphite occurs in schist host rocks as variably matured primary organic matter and as structurally-controlled hydrothermal precipitates. Hydrothermal graphite is particularly enriched in Macraes deposit, in micaceous shears.

Kinematic indicators in shear zones
1992Shear zones are fundamental components of all continental margin orogenic belts, irrespective of style or age. They can occur at any depth in the lithosphere and may be cataclastic, transitional, or mylonitic. They dominate much large- and small-scale lithospheric deformation and control the formation and siting of many economic deposits.

Abstract Shear zones may be classified into brittle, brittle-ductile, and ductile shear zones. The geometry and displacement boundary conditions of these zones are established. The geometric characteristics of ductile shear zones relevant to geological studies are described: orientations and values of principal finite strains, rotation, and ...

Abstract Shear zones that have widened with time can display margin-to-interior microstructural profiles unlike the real microstructural history of the interior rocks. Shear zones that have not widened with time can provide more reliable views of microstructural history, and therefore of deformation processes.
