Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

The extreme mobility of debris avalanches: A new model of transport mechanism [PDF]

, 2015
International audienceLarge rockslide-debris avalanches, resulting from flank collapses that shape volcanoes and mountains on Earth and other object of the solar system, are rapid and dangerous gravity-driven granular flows that travel abnormal distances.

GEOCHRONOLOGY OF LITHIUM-BEARING GRANITOIDS OF INGUL MEGABLOCK (UKRAINIAN SHIELD)

Visnyk of Taras Shevchenko National University of Kyiv. Geology, 2018
Rare-metal elements are strategic metals which, in general, are extremely important for economic development or maintenance of defence capability of any country at the modern level. The list of needs for these strategic metals ranges depending on the level of economic development of certain country, but in general it includes such elements as Li, Ta ...

Holocene subaqueous landslide dynamics in the Lake Siljan‐Orsasjön Basin, south‐central Sweden

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Subaqueous landslide areas studied by multibeam bathymetry, sub‐bottom profiling and sediment coring reveal complex stratigraphies, suggesting mass movement events starting close to the area's deglaciation and up to very recent times. Abstract The Siljan‐Orsasjön Basin in south‐central Sweden hosts two prominent lakes.

Pitfalls and limitations in seismic attribute interpretation of tectonic features [PDF]

, 2015
Seismic attributes are routinely used to accelerate and quantify the interpretation of tectonic features in 3D seismic data. Coherence (or variance) cubes delineate the edges of megablocks and faulted strata, curvature delineates folds and flexures ...

The possible degassing nature of some local structures of concentric and zonal structure on the territory of the Volyn-Podolye plate and the Western part of the Ukrainian Shield and the way of their subsequent study

Геофизический журнал, 2020
The article considers some specific features of the fracture-block structure of the Podolye and Volyn megablocks of the Ukrainian Shield, as well as the Volyn-Polesye volcano-plutonic belt (within the sheet of M-35-IX — «Kostopol») in connection with ...
