BAGHANWALA— BASSEIN. 23 



Balaghat gneiss Term proposed by W. King (Mem., Geol. Surv., 



Ind., XVI, 125, 1880) for the gneissose granites, generally red- 

 dish in colour, typically developed in the western parts of 

 North Arcot, in the Cuddapah sub-division, in the eastern part of 

 Bellary. in Kurnool and over the eastern portion of the 

 Hyderabad territory up to the higher reaches of the Godavari. 

 Similar rocks have been referred to as the Bellary gneiss and. 

 Hosur gneiss, and the rocks appear to be approximately similar 

 to the so-called Bundelkhand gneiss of Central India. 



BaJmir sandstones. — See Banner sandstones. 



Banganapalli Stage.— Named by W. King (Rec, Geol. Surv., Ind., 

 II, 8, 1869 ; Mem., Geol Sun'., Ind., VIII, 40, 1872) from the town 

 of Banganapalli (15° 19' ; 78° 17'), the headquarters of a state in 

 the Kurnool district. It is the lowest stage of the Kurnool 

 series, and is distinguished by the occurrence in it of diamonds for 

 which numerous old workings are known. 



Bap beds. — Boulder beds found by B. D. Oldham (Rec, Geol. Surv., 

 Ind., XIX, 123, 1886), near Bap (27° 22' ; 72° 23') in Jaisalmer 

 State were regarded as similar and equivalent to the Pokaran beds 

 (q.v.). 



Barakar Stage.— Name suggested by T. Oldham (Mem., Geol. Surv., 

 Ind., Ill, pt. 1, 212, 1861) for the lowest stage of the Damudas 

 previously known as the Lower Damudas. Named from the 

 Barakar river, which runs over the Barakar and other stages of 

 the Raniganj coalfield to join the Damuda. 



Barmer (Balmir) sandstones.— Distinguished by W. T. Blanford 

 (Rec, Geol. Surv., Ind., X, 17, 18, 1877) as one of the divisions of 

 the Jurassic rocks in Jaisalmer, and named from the town of 

 Barmer or Balmir (25° 45 '; 71° 25') in Marwar. Similar beds 

 east and south-east of Jaisalmer were distinguished as the Lathi 

 beds by R. D. Oldham (Rec, Geol. Surv., Ind., XIX, 158, 1886). 

 T. H. D. La Touche suggested (Mem., Geol. Surv., Ind., XXXV, 

 33, 34, 1902) that these beds are not older than Cretaceous, as 

 they include remains of dicotyledonous angiosperms and underlie 

 beds that resemble the Nummulitic " Multani mitti." 



BaSSein series.— Name proposed by F. Noetling (Pal. Ind,, New 

 Ser., I, 5, 1899-1901) for the Nummulitic rocks of Burma, which 

 were described by W. Theobald (Mem., Geol. Sure, Ind., X, 278, 

 1873) under the latter name. Besides the Nummulites, the
