I92I. No. 8. O.N THE ECLOGITES OF .NORWAY. 55 



Other occurrences iZöblitz, Waldheim, Böhrigen, Geiersdorf, Molsdorfl, were 

 later described by J. Lemberg' and E. Dathe-, and the eclogite is said to 

 occur as "lavers" (Schichten) stratified in the serpentine. The latter mostly 

 contains cr3'stals of garnet and diopside, the occurrence having an apparent 

 resemblance to that in Almklovdalen. Near Heiersdorf the olivine is non- 

 serpentinized (Dathe, loc. cit., 1876I. 



The garnet-bearing serpentines near Kremze in Southern Bohemian 

 Forest were first described by F. v. Hochstetter-^, who states that eclogites 

 occur in alternation with gneiss, serpentine, garnet-bearing hornblende-rock 

 and coarse-grained granite. Later A. Schrauf* distinguished three main 

 zones, called the zone of olivine-serpentine with pyrope and sparing ompha- 

 cite, the zone of enstatite-omphacite and the zone of diallage-garnet-rock. 

 The garnet of the last-named, apparently an eclogite, is said to be alman- 

 dite. Unfortunately it is not clear from Schraufs description, whether this 

 rock occurs as inclusions in the olivine-serpentine or is associated with the 

 gneiss. From Hochstetter's statements the latter relation seems more pro- 

 bable. But even if there are no eclogitic inclusions in the Bohemian 

 pvrope-olivine-rock, their minerals, the pyrope and the chrome-diopside 

 ("omphacite") are quite the same as those in the olivine-rock of Søndmøre. 



Eclogites in the oli\ine-rocks also occur in the Forest region of Lower 

 Austria. According to F. Becke^ eclogite within serpentinized pyrope- 

 olivine-rock crops out near Wauzenau and is found as boulders derived 

 from pvrope-serpentine areas at Briinnel-Leiten and near Altenburg. Becke 

 states the character of these eclogites as "Anhäufung derjenigen Minerale 

 welche im Pvrope-Olivinfels akzessorisch auftreten: pyropähnlicher Granat, 

 und ein oft durch Cr intensiv grüngefärbter monokliner Pyroxen". The 

 same interpretation holds good in the case of the segregations in the 

 olivine-rock in Sondmere. 



U. Grubenmann^ studied the garnet-olivine-rocks in the Gorduno 

 \'alley. The crystals of garnet, which is a pyrope of the composition 

 Fe.2oMg66Cai4, attain the size of a fist, but no aggregations of the eclogite-
