- Why is Fennoscandian Shield redirected to this Baltic Shield page? I find this term confusing since the Baltic States are not on the "Baltic Shield". I am going to copy the relevant information to the link Fennoscandian Shield and change the terminology. Is this ok?
The "Baltic Shield" is the same as the "Fennoscandian Shield" and both terms are in use, depending on habit. However, the latter term has been forced by Finnish geologists only 10 years ago, but the former was entered in the literature already at the end of the 19th century. All the Baltic States 'are not' on the Baltic Shield. Formerly, the "Baltic States" only referred to those countries with access to the Baltic Sea. In any case, this is irrelevant as to what constitutes the Baltic Shield.
The big confusion is the use of the term "Baltic Shield" to apply to all of the "Baltica Plate." See the note that I added at the end of this article. Valich 21:26, 26 July 2006 (UTC)
[edit] Depth discrepancy?
On the Kola Borehole page, it gives the thickness of the baltic shield at around 35 kilometers. This agrees well with the estimates of crust thickness in the plate tectonics and continental crust pages. The figure of 250-300 km thickness on this page looks like a typo to me.
- Yes, but on the other hand 35 km sounds too thin.--Jyril 19:57, 3 May 2006 (UTC)
[edit] Number of glaciations
- "...five successive Pleistocene glaciations and subsequent retreats..."
There has been certainly much more than five glaciation periods during Pleistocene (see timeline of glaciation).--Jyril 19:57, 3 May 2006 (UTC)
[edit] Baltic Shield thickness
A paper by A.C. Johnston, Science v. 274, 1996 Nov 01, p. 735 gives the depth as 48 km to the Moho.
