Excavations made in connection with mine development in Bailadila Iron Ore Deposit No.5 and surrounding areas have provided valuable information about the geology of this region. On this basis, an attempt has been made to evolve the stratigraphic sequence in the southern part of the Bailadila Range in Bastar District of M.P. In the opinion of the authors Loa conglomerate placed at the base of Bailadila Iron Ore Series (Group) by Crookshank should be placed in the middle. Some of the rock units placed in the so called Loa Stage are considered by the authors to belong to Bailadila Iron Ore Group.- Geothermometry and Oxygen Barometry of Coexisting Iron-Titanium Oxides of Majhgawan Diamondiferous Pipe, Madhya Pradesh

Geothermometry of the coexisting magnetite-ilmenite (Mt-Ilm) pair from Majhgawan diamondiferous pipe indicates a temperature of 1150°C. The values of fO2 T and P fall in the equilibria field defined by iron-wustite (IW) and wustite magnetite (WM) indeating depth of sampling of about 155km and pressure of 46kbar.Keywords

The compositional trends in ilmenites from Majhgawan indicates slightly increased values of -log f02 i.e., 9.2. The divariant plots of Fe2O3 vs MgO and Cr2O3 vs MgO indicate resorption of most diamonds. The rounded-dedecahendra from indicates a preservation percentage of 65-70. The wine-red garnets from diamondiferous pipe are moderately subcalcic. The CaO vs Cr2O3 plot shows that they fall very close to the 85 percent Gurney line indicating emplacement at the craton margin having moderate diamond content. Geothermobarometry based on the co-existing pyropeknorringite and spinel geothermobarometer for the diamondiferous pipe yielded an equilibration temperature and pressure of 1160°C and 47 KbaT.Keywords

The results of analysis (Fe) of the blast samples and the channel samples collected during prospecting of iron ore deposit of Bailadila, are compared metre by metre and the corresponding statistical parameters determined. It is generally observed that in the iron ore portion of the excavation, the comparison is good, but in the shaly portions there is wide variation.- Bioaccumulation Pattern of Heavy Metals in Fish Juveniles of Indian Sundarbans
