262 WYNNE : GEOLOGY OP KTJTCH. [pART II. 



The lowest part of the traps. No. 2, Section A B, are olive 

 and earthy, succeeded by the ordinary frangible basaltic kinds. These 

 pass upwards into the sub-nummulitic, or lateritic series. No. 3, as 

 follows, the junction being shown in natural order : — * 



6. — Bed and white pseudo-breccia, earthy. 

 5. — White, unctuous, and chalky clay. 



4. — A more pseudo-brecciated band with large white earthy 

 StrB-NUMM0LiTlc ...-{ blotchcs— probably volcauic. 



13. — White and red mottled bed, a variety of ferruginous ash 

 with much silicate of alumina. 

 L 2. — Pale purple lava-ash, a thin band. 

 Teap ... ... 1. — Concretionary trap, or ' basalt wacke.' 



These red and white earthy beds undulate in the stream course near the 

 line of section and overlap a mass of coarse, soft, yellowish rugged 

 sandstones exactly such as frequently occurs in the Jurassic formation. — 

 No. 1 in Section. 



Southward of this the earthy brecciated rocks again appear. 

 No. 3, associated with some highly ferruginous and hsematitic black 

 and red bands, both abutting near the section line against a protru- 

 ding mass of Jurassic sandstone marked upon the sketch map, Plate VI. 

 Some of the white earthy rocks here contain scattered grains of 

 quartz, and are associated with obliquely laminated, soft, red, white, and 

 yellow sandstones much resembling the jm-assic rocks. 



At this place the traps have an undulating dip to the south at 5°, 

 the flow in junction with the volcanic-looking earthy breccia being as 

 usual spheroidal. One of the spheroids here was 8 feet in diameter, its 

 centre being occupied by a cluster of smaller concretions. Another, 

 measuring 3 feet 6 inches across, was occupied by the lavender, gray, 

 unctuous, volcanic-looking rock with white specks, and the surface of 

 the trap flow supported small patches of laterite. 



* At a little distance east of the section here some sandstone of very Jurassic aspect 

 is seen at the place marked J upon the sketch map, PI. VI.
