JOÜKNEYS THROUGH KOBEA. 125 



It is the eastern termination of the " spatulate area " which we 

 liave traced from Chi/ang-s'öng^\ 



On the way from Mu-juu to CJii-i'u'ôl in Kijöiig-sang-Do over 

 the well-known Tai-tok-san pass, there occur a number of abnormal 

 eruptives represented in Yabe's collection. (3ne rock is a talcose 

 quartz- schist which probably resulted by pressure-granulation from 

 aplite. The other is an orthogneiss showing crj^stallization- 

 schistosity : the (|uartz and orthoclase of the rock are so aggre- 

 gated as to produce a granular implication- structure. The third 

 is a fusion-breccia of the character of quartz-porphyry, contain- 

 ing abundant fragments of quartz in the cryptocrystalline ground- 

 mass of fluxion -structure. 



All tliese rocks bear tlie stamp of a marginal faciès of 

 granitic magma, and though interesting from the standpoint of 

 petrology, simple inspection of rock- specimens is of no help in 

 ascertaining their geological relations. One thing, however, is 

 certain, viz., tliat the sericite- schist which closely resembles that 

 of the typical Taunus schists, has resulted from one of the two 

 last-mentioned by a katamorphic shearing of the crust. The 

 typical sericite- schist is found at the province -boundary along 

 the railway cutting at the w^ell-known Chhiju-phung-nij'ôwj pass ^\ 

 This so-called Metamorphic Mesozoic (Algonkian ?) lias already 

 been referred to as occurring at Tong-pok^^. 



After this short digression, I now resume my itinerarj'- from ^. 

 Chln-an. The eunmal is at the water-shed (about 300 m), the 

 streams on one side flowing to the southern archipelago, on the
