XXVII, 58, 1894). The Deoban limestones were regarded by 

 Oldham to be older than the Simla carbonaceous system. 

 Rocks of this kind strongly resemble some of those among 

 the Cuddapahs and other parts of the Purana group in Penin- 

 sular India. 



Deola and Chirakhan marl. — Middle division of the Bagh Cretaceous 

 beds recognised by P. N. Bose (Mem., Geol. Sun., Ind., XXI, 

 2, 35, 39, 1884) and regarded as approximately equivalent to 

 the Trichinopoly stage of the Coromandel Cretaceous forma- 

 tions (he. cit., 41). Deola (22° 20' ; 75° 12') and Chirakhan (22° 

 23' ; 75° 12') are villages in the Lawani district of the Indore 

 State. 



Dhaman. — A Persian word meaning a skirt, often applied to the 

 great alluvial fans formed at the base of the hills in Persia, 

 Baluchistan and Afghanistan. 



Dharwar system.— E. B. Foote in 1882 indicated that in South 

 India three sub-divisions would have to be recognised among the 

 crystalline rocks to distinguish those intermediate in character 

 between the typically schistose and the typically granitoid rocks 

 of Mysore and the South Mahratta country (Bee, Geol. Surv., 

 Ind., XV, 202). In 1886 he proposed to distinguish those which 

 he described generally as " sub-metarnorphic " by the name of 

 Dharwar (Rec, Geol. Surv., Ind., XIX, 98), from the district and 

 town in the southern part of the Bombay Presidency. He re- 

 garded the Dharwars as resting unconformably on the granitoid 

 gneisses, and to be younger generally than the rest of the crys- 

 talline complex. The bands of Dharwars exposed in South 

 India were regarded as mere remnants of a great spread of the 

 system of rocks which once covered the gneisses (Mem,., Geol. 

 Surv., Ind., XXV, 74). The rocks of the system include — 

 hornblendic and chloritic schists, hematitic quartzites, phyl- 

 lites and sometimes metamorphosed conglomerates. The horn- 

 blende-schists are sometimes altered basic igneous rocks which 

 occasionally retain the original diabasic structure. The whole 

 assemblage of rocks thus resembles generally those known as 

 the Lower Huronian of Canada, and various occurrences of the 

 kind associated with the Archtean basement complex in differ- 

 ent parts of the world. Some of the gneissose granites show 

 locally an intrusive trespass with regard to the Dharwars ; in 

 other cases pebbles of gneiss are found in the conglomerates of
