is cut through by a dyke of granite, probably 

 belonging to the T'ai-shan complex, which forms 

 the basal complex of the formations of the Wu-t'ai 

 Hsien district. 



We crossed the alluvial plain and reached Hsin- 

 chou, at which point we joined the route taken 

 by Bailey Willis' party on its way from Wu-t'ai 

 Hsien to T'ai-yuan Fu. 



Striking south from Hsin-chou, we crossed 

 the south-western terminus of the Ki-ch'ou Shan, 

 where occur the typical Sinian limestones, which 

 Bailey Willis has called the Ki-ch'ou formation, and 

 which are of the Cambro-Ordovician period. 



The Ki-ch'ou Shan run from north-east to south- 

 west along the south-eastern margin of the Hsin- 

 chou plain. The range consists of a massive scarp 

 on the north-west and a dip slope on the south- 

 east, as a result of an extensive fault, running in 

 the same direction as the range. This fault is one 

 of a series, which, as already stated, extend down 

 through Shansi. The next in the series occurs, in 

 the opinion of the author, along the north-western 

 margin of the T'ai-yiian Fu plain, where again the 

 limestone rises in a massive and precipitous scarp ; 

 only in this case the downthrow is on the south- 

 eastern side. Considering the general westerly dip of 

 the strata from the Chihli plain to well west of T'ai- 

 yiian Fu, and the merging of the upper rocks of the 

 Shansi formation into the T'ai-yiian plain on its east- 

 ern margin, the sudden recurrence of the limestone
