PLATE XXXII. 



Fig. 1.— Thu riniinal of Clilijaug-nyöng (^ ^) with tlio nsiml tidjuiict of 

 moimtaifl -castle behind. The precipitous raountaiu is built up of 

 aplitic masanite capped with reddish and greenish beccias which 

 correspond to the uppermost member of the Kyöng-sang formation. 

 The masanite liere, as in other occurrences, is an intrusive rock ; 

 but how it came to be exposed in steep walls is not exactly known 

 to me (p. 133). It may be attributed either to erosion or to 

 slipping on the Avest or the Nak-tong-gang side. 



iMg. 2.— An equatorial valley between Yöng-san (^ iJj) at the angle of the 

 Nak-tong-gang and Sam-nang-jin station, running parallel to the 

 course and north of the river. I consider this to be a typical dis- 

 location-valley cutting through the almost horizontally bedded 

 breccia. At Ku-pak, gold dust is washed in the gravel of porphy- 

 rite-breccia and it is a new type of the occurrence of gold in 

 Korea (p. 134). 



Fig. 3.— The Kkachhi-uon gate (S^J p;t ü^) on the eastern bank of the Nak- 

 tong-gang in the terraue of felsophyre (pp. 16, 131).
