Texturanalysen von Halitmyloniten aus den Salzstrukturen Gorleben, Morsleben und Teutschenthal
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Das Verständnis der Mechanismen und
der Prozesse der Gefügeentwicklung und
die damit verbundene Charakterisierung
der anisotropen physikalischen Eigenschaften
von natürlich deformiertem
Steinsalz sind von grundlegender ...
Grain coarsening and hydrothermal alteration in metacarbonates of the Damara Orogen, Namibia
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Grain coarsening is a process that occurs
in a wide variety of rock types. The
application of grain growth theory to
natural geologic materials has its beginnings
in the theoretical foundations of
the metallurgical ...
Gypsum veins as hydrofractures in layered and faulted mudstones: implications for reservoir permeability
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Mineral veins form when water solutions
passing through fluid-transporting
fractures gradually seal the fractures
as minerals precipitate. Many mineral
veins are hydrofractures, that is, fractures
generated at least partly ...
GPS-gestützte Kartierung gravitativer Massenverlagerungen an der Röt/ Muschelkalk-Grenze im Göttinger Wald
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Gravitative Massenverlagerungen entlang
der Muschelkalkschichtstufe gehören
zur natürlichen Morphodynamik.
Durch die unterschiedliche Erosionsresistenz
der relativ inkompetenten Ton- und
Mergelsteine
des Röt und der direkt ...
Structural record of an oblique impact: the central uplift of the Upheaval Dome impact structure, Utah, USA
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Most asteroids strike their target at
an oblique angle (Pierazzo & Melosh
2000). The common criterion for identifying
craters formed by an oblique impact
is the pattern of the ejecta blanket.
On Earth, however, ejecta ...
Measurement of calcite crystallographic-preferred orientations by magnetic anisotropy and comparison to diffraction methods
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The anisotropy of magnetic susceptibility
(AMS) of rocks reflects the preferred
orientations of minerals. Therefore
AMS is a quick and easy way to
characterize rock fabrics (Hrouda 1982,Borradaile 1988); the obtained result ...
Holocene shield volcanoes in Iceland
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Holocene shield volcanoes (lava shields)
are common in Iceland, but they are
restricted in space and time. As regards
space, most of the shield volcanoes
in Iceland occur within two bands
in the West and North Volcanic ...
Structural contacts in the Late Paleozoic accretionary wedge of central Chile and their tectonic significance for the evolution of the accretionary complex
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The Chilean accretionary wedge is part
of a Late Paleozoic subduction complex
that developed during subduction of the
Pacific plate underneath South America.
The wedge is commonly subdivided
into a structurally lower Western ...
Structural control of fluid flow on a carbonate platform margin: an example from the Otavi Mountainland, Namibia
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The present study focuses on the northwestern
OML, southwest of the mining
town of Tsumeb. The dominating structure
in this area is the NW-SE striking
Guinas Fault. The Guinas Fault is a
shear zone that divides an area, ...
Experimental study of the evolution of fault gouge in layered sand–clay sequences
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
This study focuses on clay smear processes
during fault gouge evolution in
sand-clay sequences at depths up to
2 km. A clay-rich fault gouge can dramatically
lower the fault’s permeability,
and prediction of this process ...
