Application of Photogrammetry in Geology: 3D Investigation of Rock Fracture Distributions
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Geology as a science has an important
visual component and the knowledge of
any geologist is deeply linked to visual
experience of rock outcrops, thin sections
and analytical images. One of the
shortcomings of most geological ...
A new practical and economical technique for the obtention of high quality thin section photographs with the help of a simple optical microscope
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Microscopic study is an indispensable
step in the determination of the petrographic
characteristics of rocks. In
Cameroon just like in most developing
countries, simple polarizing microscopes
of the 20th Century constitute ...
Feldspar deformation in greenschist facies shear zones (Aar-Massif, Switzerland)
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Granitic gneisses of the Central Aar
Granite host a shear zone network
that formed at greenschist facies conditions.
The work area is located in
the Bächlital (Grimsel area, Central
Switzerland) and was chosen for the
analysis ...
Textures in mylonitised granite from Banefo area in the central part of the Cameroon Central Shear Zone (central Africa) — Kinematics and gradian deformation indicators
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The North Equatorial Panafrican belt
is constituted by orthogneissified metamorphic
and magmatic sets linked to
tectonometamorphic events of the neoproterozoic
orogeny. This belt whose
formations are situated in the North ...
Geochemische Klassifikation und Sm-Nd Isotopensystematik proterozoischer Metasedimente des Baltischen Schildes (Västervik Region, SESchweden)
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Die Västervik Region liegt an einer
Haupt-Terran-Grenze im Baltischen
Schild. Im NE schließen sich die Einheiten
des Südsvecofennischen Vulkanitgürtels
mit Altern >1,85Ga an, im SW
folgen die Granitoide des Transskandina ...
Gefügecharakterisierung von Calcitmyloniten und Marmoren bezüglich senkrecht zueinander stehender Faltenteilstrukturen, Alpi Apuane, Italien
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Im nördlichen Teil des Appenin in Italien
ist der metamorphe Komplex der
Alpi Apuane in Form eines tektonischen
Fensters sehr gut aufgeschlosssen.
Die metamorphen Gesteine der Alpi
Apuane — Metakarbonate, Kiesel- ...
Neotectonics in the Swiss Alps—A late Alpine to postglacially active fault at the Gemmi Pass
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The area of the central and western
Swiss Alps reveals not only the highest
uplift rates of Switzerland (1.5mma−1
near Brig, Schlatter & Marti 2002),
but also shows a strong concentration
of earthquakes (e.g. Deichmann ...
Evolution of the Tamtsag Basin / NE-Mongolia — part I: basin fill
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The Tamtsag Basin in NE Mongolia
is part of a widespread basin system
which formed during Late Jurassic
and Cretaceous times (Graham et
al. 2001, Qing-Ren et al. 2003). It
is filled with continental sediments and
volcanics ...
Kinematic 3D Retro-Deformation of Fault Blocks Picked from 3D Seismics
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Movement on fault planes causes a large
amount of smaller-scale deformation,
ductile or brittle, in the area surrounding
the fault. Much of this deformation
is below the resolution of reflection
seismics (i.e. sub-seismic, ...
Structural investigations of the W termination of the ‘Schneeberg Zug’ — Austroalpine Unit, Southern Tyrol: Results from a crustal scale shear zone
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The Austroalpine microplate traces the
Alpine collision event between the
Africa-related southern Alpine realm
and the European continent. The
southern margin of this microplate, the
basement to the north of Meran ...
