SGM: 179 sq.km completed. GCM: 446 sq.km completed. GPM: 60 sq.km completed. MISSION-II LSM: 38.5 sq.km completed Drilling: 714.75 m drilling completed (including extended item.) DM: 0.6 Sq.km LIMESTONE INVESTIGATIONS: Study in Larket block(northern), litang valley, jaintia hills district (on 1:5,000 scale with 5m contour interval) and ishamati block of shella - bholaganj belt, East Khasi Hills district (1:2000 scales), Meghalaya are in progress. Investigation for Limestone in Umphyrluh Block, Litang valley, Jaintia Hills District also in progress as an extended item of FS 2012-13. COAL EXPLORATION: Study in Gondwana Coal in Sukchar-Singrimari Block, Singrimari Coal Field, Dhubri district, Assam, at the border of Assam and Meghalaya (G3) in progress & two coal seam of thickness 0.55 m and 2.15 m have been encountered at 257.90 m and 262.70 m depth respectively. Borehole SN-05 was closed at a depth of 281 m on 22.05.13. Another exploration study in the area adjacent to Sukchar- Singrimari Block, Singrimari Coal Field is in progress. During regional traverses along Garobhada- Singrimari, several Tertiary sequences were noticed, near Jamali, in a road section. A shale-siltstone alteration was noticed containing with thin bands of probably lignite coal. Study in Coal Zone in Tertiary sequence is in progress around Shalibhuin in Dhubri district, Assam and Nakaigiri-Ujanggiri in West Garo Hills, Meghalaya. The Tertiary sequence trends NW-SE with very low dips varying from 5 to 10° towards SW. Based on these coal pits, one scout borehole USD-01 has been fixed and is under progress. USD-01 commenced on 03.07.2013 and has achieved a depth of 74.00 m as on 30th Sept. 2013. A basic dyke of about 10m width and also another ultramafic dyke of about 5m width, intrusive within the gneissic complex have been mapped near Shalibhuin. REE INVESTIGATION: Preliminary investigation for REE in parts of Nongpoh pluton, Ri-Bhoi district, Meghalaya (G4) is in progress. LSM: 16 sq.km. covered during the FS 2013-14. TITANIFEROUS-VANADIFEROUS MAGNETITE INVESTIGATION: The study around Rambrai in West Khasi Hills district, Meghalaya is in progress. The area exposes meta norite, light grey to pink granite gneiss banded gneiss within gneissic complex intrusive of non-porphritic granite were demarcated. During mapping delineated meta norite body associated with titaniferous-vanadiferous magnetite bands. This body trending N550W-S550E and with 1800m long X 300m wide. The analytical results of 9 bed rock samples collected from meta norite body shows TiO2 values ranges from 1.33% to 4.3% with average value of 2.45%, Vanadium values ranges from 214ppm to 1177ppm with average value of 512ppm, Cu values ranges from 3ppm to 566ppm with average value of 179ppm and Zr valves ranges from 47ppm to 1802ppm with average value of 400ppm. MISSION-III DRM: compilation of DRMs of Lakhimpur, Jorhat, Nagaon and North Cachar Hills, Assam, Jainitia Hills, Meghalaya, Aizawl and Champhai, Mizoram are under progress.

Updated Accession numbers for ‘Completed Reports’ for FS 2009-2010(3report) , 2010-2012(7 out of 43 reports) and 2012-2013(two report) Library Services = Procured 14 nos. new geology books and 91 nos. of journals in Regional Library. Nine (9) Scientific Papers and 11 abstracts were processed for different National and International Seminars/ Journals. Generated Rs 3502 through sale of GSI publications. Distributed 578 copies of GSI publications to all the Regions of GSI in India. Extended Library facilities to departmental officers and others. Geoinformatics: Scrutiny and finalization of geological maps of 3 toposheets submitted by State Unit: Assam was completed. Creation of theme based database 15 toposheets of 78O (50K theme) is completed and rest is in progress. Legend for lithology level is in progress. MISSION-IV Palaeontological Studies: Egg like fossils were recovered from Upper Mahadek Formation of Upper Cretaceous age. These egg like fossils are 4-7 inch in diameter. Upper Mahadek Fm is considered to be marine origin. If these fossils are confirmed as egg fossils, it will be the first time report of marine reptile egg fossil from Indian sediments. Thin section study suspects egg shell. SEM study is proposed for confirmation. Geotechnical Investigations: Request from Kameng H.E.Project, West Kameng district, Arunachal Pradesh, Tuirial H E Project, District Kolasib, Mizoram & Mawblei H.E.P, West Khasi Hills District were attended. Medical Geology: Systematic spot analysis of groundwater and surface water samples by Merck Arsenic Field kit were carried out in the field in Toposheet 83 B/12 & B/16 to study of arsenic contamination in water and soil in parts of nagaon and marigaon districts, Assam. Landslide Hazard Zonation: Updation of existing landslide inventory of NER, Macro scale Landslide Hazard Zonation in along road corridor of Anjaw district, Arunachal Pradesh & road corridor of Sikkim, Site Specific Geological Studies of the landslides near Tawang Monastery, Tawang district, Arunachal Pradesh & Proposed Pakyong Airport Area, Sikkim, Detailed Study of the 13th Mile Landslide on Gangtok- Nathula Road, East District, Sikkim are in progress. Earthquake Studies: The Seismic & Landslide Hazard Assessment of Aizawl town, Mizoram and Kohima city, Nagaland is in progress. Study of SRTM data to delineate different geomorphic /morphotectonic units and Lineaments for Seismic Hazard Assessment of Gangtok and surrounding areas of Sikkim is in progress.
