158 ART. 2, — B. KOÏÔ: 



of the two i'oimations I am, however, disposed to inckide them 

 in a single series. 



The present Phylhte series occnrs in four parallel bands on 

 the west side of the Chiri-san massif; their trends correspond to 

 the margin of the mass, extending from the southwest to the 

 northeast exactly in the same course as the belt of the Kang-jin 

 schists ; and the bands are distiibuted so as to appear like relics 

 of beds deposited in parallel troughs of crust waves originating 

 from the massive Chiii-san. I shall begin with the innermost. 



HI. a. The Tong-pok ^^ Complex. — This occupies a bilobate 

 area between Newicj-jyu, Tcng-pol,', and Ok-kca, directly overlying 

 the Kang-jin muscovite-schist (pp. 54-55). According to Messrs. 

 Inol'te and Yabk (p. OC), a l)iotite-orthogneiss appears east of Iloa- 

 sim, being covered eastward by a wonderful complex of phyllite, 

 sandstone, schalstein, and the like, which my micioscopic 

 study showed to be metamorphosed and n.iylonitized eruptives 

 and sedimentaries. They are (1) a flagstone of fine-sandy ap- 

 pearance, which is really a banded spherulitefels of either rhyolite 

 or quartz-poiphyry ; (2) a brownish-red ferruginous tufl^ of the 

 appearance of an altered flaxseed iron ore ; (o) a grayish, highly- 

 lamellar .muscovite-schist with spots of quartz, — a kataporphyiitic 

 schist which has resulted from the crushing and dragging of 

 quartz-porphyry ; (4) a mashed carbonaceous slabstone with bluish 

 dots of (|uartz, — a kataclastic coaly sediment ; (5) a katamor- 

 phosed and anamorphosed, blackish grit of either igneous or 

 sedimentary origin; (G) lenticular masses of giaphitoid some 30 

 feét in thickness imbedded in No. 5. The analysis of a speci- 

 men of graphitoid from Kui-am'-^ gave the following result "\- —
