Uranium resources of the world is estimated to be 5.5 million tonnes and the proven resources in India forms 3% of the world resources. The biggest uranium deposit is the Olympic dam deposit in Australia, which contains nearly 2.45 million tonnes of 0.023% U 3 O 8 , while the highest average grade of nearly 21% is established in the McArthur river deposit, Canada. Another very high grade deposit, the Cigar lake deposit, is also in Canada with an average grade of nearly 18%. Most of the uranium deposits established in India so far falls under the category of low grade. These low grade uranium deposits are distributed mainly in Singhbhum Shear Zone, Jharkhand; in parts of Chhattisgarh; Southern parts of Meghalaya; Cuddapah Basin, Andhra Pradesh; in parts of Karnataka and Aravalli-and Delhi Supergroups, Rajasthan and Haryana. These deposits are mainly hydrothermal vein type, stratabound type and unconformity related. The Singhbhum Shear Zone, Jharkhand hosts seventeen low grade vein type uranium deposits, aggregating about 30% of Indian uranium resources. The stratabound uranium mineralisation hosted by Vempalle dolostone extends over 160 km belt along southwestern margin of Cuddapah Basin in Andhra Pradesh and acco unts 23% of the Indian resources. Though the dolostone hosted Tummalapalle uranium deposit was established in the early nineties, because of techno -economic constraints, the deposit remained dormant. As a consequence of the development of an innovative pre ssure alkali leaching process, the deposit became economically viable and a mine and mill are being constructed here. Recent exploration inputs are leading more such strata-bound low grade uranium deposits in the extension areas of Tummalapalle. Nearly 10 blocks have been identified within a 30 km belt which are being actively explored and a large uranium deposit has already been proved in this province. The deposit at Tummalapalle and adjoining areas is likely to emerge as one of the larger deposits in the world. The northern parts of Cuddapah basin in Andhra Pradesh is the host for unconformity related low grade uranium deposits. Four low grade low to medium tonnage deposits viz. Lambapur, Peddagattu, Chitrial and Koppunuru have been established in this province along the contact between basement granite and Proterozoic sedimentary rocks. This province also holds promise for large tonnage-high grade mineralization in the deeper unexplored parts of the basin. The North Delhi Fold Belt in the states of Rajas than and Haryana is the host for albitite/vein type uranium mineralization. A 320 km long NE-SW trending zone of deep seated fractures is the locus of mineralization and the mineralization is caused by soda metasomatism. A low grade uranium deposit is already established at Rohil associated with albitites and vast areas in this zone is open for exploration. The Cigar lake deposit, one of the two very high grade deposits in the world, though discovered in the year 1991 remains unexploited because of it high grade and requirement of remote handling and high end mining technology. The Mc Arthur deposit is being mined by raisebore mining method and the entire operation is carried out by 750 employees. Because of the high grade nature of the ore, it is diluted with barren rocks to bring the grade into manageable level before the beneficiation. The Rossing uranium deposit in Namibia, the biggest opencast mine for uranium, is of low grade and produces nearly 8% of the global output. As a result of the massive minin g and beneficiation operation, the employment of manpower is also very high compared to the high grade deposits. India, being a developing country with a high rate of unemployment, should treat the low grade deposits as an opportunity for employment.

Bibliometric analysis was used to assess the research productivity of the Wadia Institute of Himalayan Geological (WIHG) during 1991-2020. Data was collected from the Scopus database, and VOSviewer software used for visualization. The study focused on various bibliometrics parameters like year-wise research growth, Authors productivity, Growth rates measures (AGR, RGR, Dt), Collaboration measures (DC and CC), subject-wise distributions, most prolific authors, highly collaborative institutions, most cited documents, top funding agency, types of documents, etc. The results showed that the maximum number of documents, 93 (7.21%), were published in 2017. India and the United States of America contributed the highest numbers of documents, 1289 & 97. The highest number, 995(60.78%) of scholarly publications, has come from the subject of Earth and Planetary Sciences. P Srivastava is the most prolific and highly cited author. WIHG collaborates with many IITs like IIT Roorkee, IIT Kharagpur, and central universities such as HNB Garhwal University, BHU, etc."The Randolph glacier inventory: A globally complete inventory of glaciers" is the most highly cited publication in the Journal of Glaciology by Pfeffer et al. in 2014 with 515 citations. "The Current Science," has the first rank of productive and cited source with 156 documents and 2380 citations.

In modern time, the work of the library is not confined only to the transaction of the books, but it has become the centre of dissemination of information. during past 93 years (1939-2013) have been analyzed to find out the trends and areas of research, growth pattern and productivity of Department along with broad subject areas in the discipline. This study presents the analysis of the study with the primary goal of appraising the perspective of geological research community to make them aware of the present direction of research in geology.

Dear Editor, I have read the above cited paper [1] very carefully. Undersigned has been involved in the analysis of geological materials and hydro-geochemical reconnaissance surveys attached with mobile geochemical laboratories in different parts of India for uranium exploration activities of Atomic Minerals Directorate for Exploration and Research. I have also contributed research papers on uranium determination in diverse matrices. Based on my experiences gained so far, I would like to share some of my observations as follows: The authors statement and claim on page 3 of the manuscript under section: uranium estimation, the details of model/make of the instrument is missing in the cited paper [1]. As stated by them, quote ‘‘For uranium quantification at ultra trace levels in water laser fluorimetry technique is used which is based on the measurement of fluorescence of uranium complexes in aqueous solution. In this technique, on excitation of uranium complexes with UV light of 337....
