JOURNEYS THROUGH KOREA. 43 



eye-gneiss of the Chin-ji/ii ridge. The same Hadong gneiss con- 

 stitutes the snow-clad Cldrl-san massive (1942 m) and probably 

 also the needle of Ok-knl-bowj. At Tloa-kcïl-ji/anr/, a copious supply 

 of water was flowing from the Chiri-scni, and I saw in the recesses 

 of the mountains, four kilometres from us, a number of large 

 monasteries, one being the Ssanfj-gijol-xa '\ sheltering one hundred 

 bonzes. This is one of the three celebrated monasteries of 

 Korea. 



We left Ilao-käl-Ji/am/, and near by on t1ie road side was 

 found a large detached, scalenohedral block of the Hadong gneiss, 

 called Mil-bahoi ^\ It marked the boinidary between Kij'6ng-sang- 

 Do and Chgöl -la-Do. About a quarter of an hour later, we reached 

 a place where a steep side-valley joined tlie river. This was the 

 end of the Hadong rock, and further on towards the west a 

 gneissose granite was seen with tlie axis of schistosity striking N. 20° 

 E., and a slight dip to the west. It is a bufl-coloured, friable, 

 rather coarse-grained variety rich in biotite, representing the sort of 

 rock whose terrane (the Hadong eye-gneiss) we had just gone over, 

 but the characteristic large " eyes " are wanting, and sillimanite, 

 a piezocontact mineral, can be seen on the sheared face. 



The transverse gorge (PI. V. fig. 3) ended at Ila)i-su-nai^\ and 

 we came out on an open flat from the defile of the Ch'irl-san. On the 

 southeast side, masses of granite-gneiss liad slipped {fig. 3) down 

 into the gorge from the high peak of Pälk-un-mn, already mention- 

 ed, leaving slip-terraces on the steep slope. This was the CMn- 

 jgu fault-ridge which we fiad traced hither. To the south-west, 

 massive beds of red and green breccia ^\ interstra titled with red tuft"
