Account of Minerals 



[JULT 



57. — Floetz trap, near the line of contact, where the laterlte is seen 

 superimposed — Beder. 



58. — Basalt underlying laterite cliffs of Beder. 



59. — Termination of black veins in the laterite of Beder, near its 

 junction with the trap, in combination with iron and alumina. 



59 A. —Black oxide of manganese in combination with iron, from veins 

 in laterite of Seder. 



60. — Lateritic conglomerate, capping laterite of Beder. It exactly re- 

 sembles a similar rock, distinct from the true laterite, capping the late- 

 rite of the ghauts and Western Coast, composed of ferruginous nodules, 

 cemented together by a felspathic paste of various shades of yellow, 

 brown, and red, coloured by oxide of iron. This rock occasionally pre- 

 sents a shining glazed-like surface. In tracts where travertine and 

 limestone prevail, as in the vicinity of Bijapore, and Baugwari, the lime 

 often enters the cement of this conglomerate. 



61. — Nodule in laterite of Beder, imbedding a mineral, with a green 

 and purple iridescent hue, probably iron. 



62. — ^Laterite of the western ghauts — Devamani pass, Upper Canara. 



63. — Lateritic conglomerate, capping laterite of the western ghauts, 

 summit of Hossdroog pass. Upper Canara. 



64. — Laterite of the Western Coast, quartzy variety, from Onore. 

 Specimens of this rock from theMalayan Peninsula, Cannanore, Manga- 

 lore, the Bisley and Heggalla Passes, the lateritic rocks capping the 

 slate and sandstone ridges of the Ceded Districts, the neighbourhood 

 of Bangalore and Nundidroog, &c. have already been transmitted. 



65. — Variety of laterite from Onore— felspathic. 



66. — Do. do. Western Coast, from Compta, north of Onore, ex- 

 hibiting the externally black superficies, so often noticed in the weather 

 exposed masses of this rock. 



67. — Variety from base of western ghauts, near Meerjan. 



68. — Do. do from the vicinity of Soonda, in Upper Canara. 



69. — Do. do. from Banwassi, in Upper Canara, near the western 

 boundary of Mysore. 



70. — Lateritic conglomerate, capping the laterite cliffs which overlie 

 the floetz trap formation of the Deccan ; hiUs near the city of Gulberga — 

 Nizam's territories 



71. — Greenish white felspathic sandstone, of an earthy friable texture, 

 with small angular fragments of quartz, associated with the overlying 

 trap at Bangwari, near Belgaum. It sometimes imbeds dark ferruginous 

 nodules in a state of disintegration.
