2 MISSION-I STM (VARSHNAD) STUDY OF TECTONOMAGMATIC EVOLUTION OF VARSHNAD HILL SECTOR, SOUTHERN GRANULITE TERRAIN, TAMIL NADU. STM/SR/TNP/2010/001 SHRI N. SINGARAM P. RAJESH DURAI AND H. NAIK Shri P. Rajesh Durai, Geologist, presented the work. 1 Sweeping statement on interbanding of charnockite / khondalite may be stated only after detailed field studies. 2 There should be a clear distinction between `Background information and highlights. 3 Prograde metamorphism to be established. 4 Deformation / Magmatic episodes to be brought out. 5 Stratigraphic index and symbols are to be incorporated in the map. 6 Granites of different generations should be distinctly mapped and represented in the map. 7 Petrographic studies are to be incorporated. 8 Prorata target achieved and item should be completed as per schedule STM (KKD) STUDY OF TECTONIC FRAME WORK AND MINERAL POTENTIAL OF KANGEYAM CHINNA DHARAPURAM, SECTOR OF KINATTUKKADAVU-KANKEYAM-CHINNA DHARAPURAM TECTONIC ZONE OF CENTRAL TAMIL NADU. STM/SR/TNP/2010/002 SHRI N. SINGARAM G. SENTHIL KUMARAN AND NAVEEN KUMAR NIGAM Shri G. Senthil Kumaran, Geologist, presented the work. The committee made the following comments. 1 Pegmatites of different generations as identified are to be sampled. 2 Types of pegmatite to be distinguished by genesis/petro-chemistry and not by size. 3 Stratigraphic index and symbols are to be incorporated in the map. 4 Structural data is insufficient. 5 Peridotite and dunite should be sampled and analysed for important elements. 6 Tectonic history should be brought out. 7 Although there is a mention of two sets of gneissosity/schistosity but only one set of foliation is shown in the map. It needs further check. 2

3 8 Prorata target achieved and item should be completed as per schedule. 9 RCA allotment / expenditure to tally and reconciled against field stay.
