14. BAVILLE township. F 3 . 323 



The Clinton group. No. V. 



This group, using the word in the restricted sense estab- 

 lished in the present report, makes but little appearance in 

 Saville township. Its outcrop is restricted to the north- 

 eastern part where the axes of Tuscarora and Conecocheague 

 lift it to the surface. Its five sub-divisions may be traced 

 along both lines of outcrop but not with equal distinctness. 

 They are the following : 



5. The Sand -vein ore bed. 



4 The Ore sind rock J ^Per, soft. 

 4. 1 he Ore sand-rock, ( 1qwq ^ hard 



3. The Upper Olive shale. 

 2. The Iron sandstone. 

 1. The Lower Olive shale. 



1. The Lower Olive shale is not well exposed in the town- 

 ship. It might probably be found on the slope of Tusca- 

 rora but is mostly overlain with wreckage from the Medina 

 which forms the crest of the mountain. 



2. The Iron sandstone appears to be thin on the mount- 

 ain, as it makes little or no show in the wreckage and forms 

 no conspicuous terrace or foot-hill. Where Run gap de- 

 scends to the foot of Tuscarora is a vast accumulation of 

 stone brought down during past ages and accumulated on 

 the lower slope. But it consists almost entirely of the 

 white and red Medina without the Iron sandstone. West- 

 ward, however, this rock must rapidly thicken ; a manifest 

 terrace appears on the mountain side and in the rising slopes 

 of Conecocheague the whole ground is strew with its pecu- 

 liar flat red slabs. Here, too, occurs the fossiliferous hori- 

 zon of which fuller details may be found in the volume on 

 the palaeontology and in the appendix to the present re- 

 port. 



3. The Upper Olive shale is exposed in several places 

 along the axis of Conecocheague, where it may be distin- 

 guished by the color of the soil. But it is not conspicuous 

 and time allowed only a short examination in the township. 

 No sign of the Millerstown (Danville) ore beds was seen 

 in the township and they are almost certainly absent.
