KYAOKKYAN— LATERITOID. 73 



XXXIV, 86, 182, 1906) a Lower Lutetian age. The series can be 

 divided into : — 



3. Upper, equivalent to the Ghazij of Baluchistan. 



2. Middle, equivalent to the Alveolina limestone. 



1. Lower, or Meting shales. 



The Laki series is the coal-bearing formation of Baluchistan, 

 Punjab and Bajputana. It is separated from the Banikot below 

 and the Kirthar above by stratigraphical breaks. 



Lameta series. — Limestones, sandstones and shales of freshwater 

 origin found below the Deccan Trap in Central and Western 

 India ; so named from their occurrence at Lameta Ghat (23° 6' ; 

 79° 53') on the Narbada river near Jubbulpore, by J. G. Medli- 

 cott (Mem. Geol. Sura. Ind., II, 196, 1860) who regarded the 

 series as a lithological variation locally of the Mahadevas. It 

 was shown by W. T. Blanford, however, that the Lametas are 

 the freshwater representatives of the Cretaceous Bagh beds 

 (Mem. Geol. Surv. hid., VI, 216, 1869; Rec, Geol. Surv. Ind., 

 V, 88, 1872), and are thus of about Cenomanian age. 



Laterite. — Named by Francis Buchanan-Hamilton (Journey from 

 Madras through Mysore, Canara and Malabar, 1807, Vol. 

 II, 441). From the Latin later, a brick, on account of the 

 fact that it is usually and conveniently cut into the form of 

 bricks for building, and was called brick-stone (Itica cullu) by 

 the natives in Malabar. The two fomis high-level laterite and 

 low-level laterite were first definitely distinguished by W. T. Blan- 

 ford (Man. Geol. Ind., I, 351, 1879), but the terms were intended 

 to imply merely the position occupied by the two varieties on 

 the high lands, or near the coast, without involving any theory 

 of the origin of the rock. For recent papers and a discussion 

 on this interesting subject see Geological Magazine, 1903, 1906, 

 1908, 1909, 1910 and 1911. 



Lateritite. — Name proposed by L. L. Feimor (Geol. Mag., Dec. 

 V, Vol. VIII, p. 507, 1911) for detrital or rs-cotstructecl late- 

 rites. 



Lateritoid. — Name proposed by L. L. Fermor (Mem. Geol. Svrv. 

 Ind., XXXVII, p. 383, 1909) to distinguish those foims of 

 lateritic rocks formed by metasomatic replacement at the sur- 

 face.
