Abstract

Definite Middle Eocene larger foraminifera has been found in the limestone at Sandwa, Bidasar area, Churu district in the Nagaur-Ganganagar basin, Rajasthan. Nummulites Cf. Obtuses (Sowerby) 1840 with two forms viz., A form (Dia. 2.8 mm) and B form (Dia. 9 mm) are observed. In the type area of Kachchh, N. Obtuses has been assigned the age of Middle Eocene. This find assigns the limestone bed to Jogira Formation and it also extends the limits of the Eocene Sea in Rajasthan by 80 km towards east.

Abstract

Conventional and unscientific mining poses severe threat to life, public property and continuation of mining in the area. Incompatible land uses, huge waste dumps and large scale land transformation have resulted in land degradation, ponding, flooding, water contamination and health hazards in Makrana mining area. Segregation of dumps, compatible land use and research and development activity for use of marble slurry are suggested measures for reclamation and restoration of the degraded land.

Abstract

Tertiary foraminifera belonging to Discorbis and Quinqueloculina are discovered by the author from the limestones of Bilara Group of Marwar Supergroup. These rocks are hitherto regarded as unfossiliferous and Neoproterozoic-Eocambrian in age. The present find of foraminifera suggests that the formations are not older than lower Eocene, throwing new light on the age of the Marwar Supergroup from the study area.
