CARBONIFEROUS AND PERMO-CARBONIFEROUS ROOKS, N.S.W. 327 



(b) Germany.— In the Ruhr coal-field of Rheinland Freeh 1 

 has described a striated surface where the Permian basal 

 breccias are resting on the surface of the Westphalian 

 Coal-measures. 



(c) Netherlands. — Van Waterschoot Van der Gracht 2 

 has described and figured striated fragments occurring 

 under similar conditions in the Netherlands. The figured 

 specimens have a somewhat doubtful glacial appearance, 

 and unfortunately the area has been so disturbed tectonic- 

 ally that the possibility of "Slickensides" phenomena cannot 

 be altogether excluded. 



The above author points out that at the Preussen Colliery, 

 near Liinen, the striated blocks of hard Carboniferous shale 

 repose on a striated Carboniferous floor. He also states 

 that it is probable that the striae were not produced by 

 earth movements, as shining 'slickensides' is absent. At 

 the same time the fact must be emphasised that these 

 supposed glacial conglomerates are situated in the main 

 fault zone "the Courier Sprung" of the area. If this 

 evidence of contemporaneous glaciation in Rothliegende 

 time is genuine, the above author considers that it was 

 possibly a purely local glaciation, the gathering ground for 

 the glaciers being probably the plateau of Westphalia. 

 The geological horizon of these conglomerates is Permian 

 (Rothliegende, or Lower Zechstein). 



(d) Sicily. — G. G. Gemrnellaro 3 has published a very 

 interesting account of the Fusulina Limestone of the Valle 

 del flume Sosio, Sicily. Streptorhynchus, Derbyia, Stro- 



1 Letheea Geognostica.
