I. Introduction In the year 1913 I received from a former student of mine, Mr. P. H. S. De Wet, a consignment of rock-specimens from the neighbourhood of Parijs (O.F.S.). Among these were many pieces of a dense black rock, which, I was informed, occurs very abundantly in veins and networks in the granite. The characters of this rock seemed so remarkable that I took an early opportunity of visiting Parijs myself, in order to study the phenomena in the field. As a result of my observations, I… Expand

A centennial reappraisal of the Vredefort pseudotachylytes: shaken, not stirred by meteorite impact
Major pseudotachylyte zones constitute a spectacular component of the renowned c. 2.023 Ga Vredefort impact structure, South Africa, but it has always been difficult to explain how they were formed.Expand
The Vredefort crater is well known in the geological literature, because it is situated in the Witwatersrand Group, the repository of almost half of the world’s gold reserves, and was generated by anExpand
Pseudotachylyte in the Tananao Metamorphic Complex, Taiwan: Occurrence and dynamic phase changes of fossil earthquakes
Abstract Pseudotachylyte veins and cataclasites were studied in the mylonitized granitic gneiss of the Tananao Metamorphic Complex at Hoping, Eastern Taiwan. The aphanitic pseudotachylyte veins varyExpand
Pseudotachylite from the Vredefort Ring, South Africa
Pseudotachylite, a very fine grained glasslike rock, forms veins and the matrix of breccias in the core and overturned collar rocks of the Vredefort ring. The cataclastic character of coarseExpand
An argument against the crush origin of pseudotachylytes based on the analysis of clast-size distribution
Abstract The origin of pseudotachylytes has been controversial since Wenk cast doubt on the melt origin of the matrix of pseudotachylytes, in 1978. The matrix of this rock is so fine grained that theExpand
The destiny of a clast within a molten pseudotachylyte Vein
Pseudotachylytes are important markers that can indicate the thermal state during a coseismic slip failure and provide indirect information about the level of stress and sliding velocities attainedExpand
Chemical heterogeneities of Caledonian (?) pseudotachylites in the Eidsfjord Anorthosite, north Norway
The 1.8–1.7 Ga Eidsfjord Anorthosite Complex on Langøy, Vesterålen, north Norway is thrust over monzonitic gneisses in a 100-m-wide fault zone. The anorthosite contains abundant pseudotachylite whichExpand
Pseudotachylitic breccia and microfracture networks in Archean gneiss of the central uplift of the Vredefort Impact Structure, South Africa
Since 1916 the Vredefort Dome, the erosional remnant of the central uplift of the Vredefort Impact Structure, has been known as the type locality for what has been known as “pseudotachylite”, whichExpand
Occurrences of pseudotachylyte at the East Bull Lake and Shakespeare–Dunlop intrusions, Ontario, Canada
Pseudotachylyte bodies were recently identified within and adjacent to the Early Proterozoic East Bull Lake and Shakespeare–Dunlop intrusions, located approximately 25–40 km west-southwest of theExpand
Pseudotachylyte and ultramylonite bands in relation to shear zones of the Iberian Massif (Portugal): geotectonic and Variscan palaeoseismicity implications
Pseudotachylyte is regarded as a friction melt developed during brittle faulting at depths within the crust that approximate the seismogenic zone. It is a dark, very fine-grained fault rock, whichExpand
