 Sandstone. Sandstones of a

 few beds of red or yellow 

 shales. Plants, Lepidoden- 

 dron &c. 



Dark-grey and brownish shales, 

 with fossils abundant, of a De- 

 vonian or Carboniferous Lime- 

 stone type; beds of brown 

 rippled sandstone, with long- 

 winged Spiriferi. 



Table-mountain Sandstone, and 

 sandstones of the littoral range 

 of mountains generally ; grey 

 sandstones, conglomeratic at 

 base, reddish shaly below. 



Slate and grits, usually of a 

 greenish, grey, or brownish 

 colour ; beds, as usually seen, 

 vertical, or at high angles, 

 broken through and altered 

 by granite. 



Grneiss, granitic gneiss, and me- 

 tamorphic schists, limestone, 

 &c.; Namaqualand, Bushman- 

 land, Kalihari Desert, and a 

 great part of the interior.

 George Districts, Namaqua- 

 land, &c. (Minerals — schorl, 

 garnet, kyanite, fluor-spar, &c.) 



Greenstone, syenitic greenstone, 

 basaltic greenstone, amygda- 

 loid, &c., occiu-ring chiefly in 

 beds and dykes in the 'Middle'

 in the gneiss. Minerals — calc- 

 spar, sulphate of barytes (in 

 one place only), asbestos, epi- 

 dote, prehnite, agate, chal- 

 cedony, &c. The crystalline 

 felspar-trap, associated with 

 the copper of Namaqualand,

 granitic in character. A pecu- 

 liar felspar-trap -conglomerate 

 occurs in the Boggeveld Spitz.
