Sarntal Alps / Monti Sarentini Additions and Corrections
[ Post an Addition or Correction ]
|Good page but some confusion about directions:|
Jaufen Pass and Penser Joch are both N-S connections as Passeiertal and Sarntal are N-S valleys.
Sterzing is in the North and Brixen in the West.
Some additions to geology:
Only a few but prominent peaks (such as Weißhorn) are made of limestone - marble. Almost all of the mountain group is composed of paleozoic crystalline rocks (gneisses, schists, quartz-phyllites) and volcanics (Bozener Quarzporphyr in the southern part of the mountain group). From the geological point of view the borders of the mountain group differ. Most prominent feature is the Periadriatic Line which marks the border between the East Alpine tectonic system (in the North) and the Southern Alps. This line runs through the upper Penser Valley over the ridge near Rotwandhütte to Meran. As a result the mountain ridge with Weißhorn, Hochwart and Hirzer belongs to the East Alpine Stubai-Ötztal Crystalline Complex while the rest belongs to the Southern Alps. Along the Periadriatic Line younger granites came up.
The earth pyramids of Ritten are not composed of some "normal gravels with dirt" as you described but are made of glacial till. The grain size distribution of this sediment shows a very poorly graded chaotic sediment with a high amount of fines (silt) but also huge boulders.

|Thanks a lot for the explanations. My sense of direction is a bit poor and I haven't really spent much time figuring out the geology. I'll quote you on the page.|
