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-ytian Fu. 
Striking south from MHsin-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. Therange 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- 
ytian 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
