Abstract

In the present study, the rate of growth of Indian earth science literature was determined by calculating relative growth rates and doubling time for total number of all types of publications and pages separately for the period 1978-88. The results show that the mean relative growth rate has shown a declining trend from 0.35 during 1979-83 to 0.11 during 1984-88. Correspondingly, mean doubling time has increased from 2.6 years to 7 years for the same periods. The mean doubling time for Indian earth science literature is 4.8 years which is slightly less than the growth rate of earth science literature as a whole. The growth curves and chi-square values obtained show that the growth of Indian earth science literature follows logistic pattern of growth. The results of the study related to scientific productivity of authors show that the percentage of authors contributing olle publication is 63% of the total number of authors which is fairly close to Lotka's predicted value of 60%. The scientific productivity of authors is found to conform to Lotka's law and distribution of the scientific productivity follows negative binomial distribution.

Abstract

A ranking list of 26 journals most frequently cited by Indian earth Scientists during 1983-88 has been drawn using the absolute number of citations received by each journal in the baseline journal, 'Journal of the Geological Society of India'. Comparison of the present ranking list of the core journals with other national ranking lists prepared from the utility point of view of Indian earth scientists shows that the 'Journal of the Geological Society of India' occupies the first place in all the lists indicating the national bias in citing references. Further, the five journals, namely, (i) Nature, (ii) Geological Society of America Bulletin, (iii) journal of Sedimentary Petrology, (iv) American Journal of Science, and (v) Journal of Geophysical Research, appear in all the national and international core lists under study. These five journals are considered as the 'Prime Core Journals' in the discipline of earth science.

Abstract

Major lineaments of Karnataka State with length more than 100 km were mapped using satellite remote sensing data and were correlated with the earthquake occurrences. The results of the study show that there are 43 major lineaments and 33 earthquake occurrences with magnitude above 3 (since 1828) in the State. 23 of these earthquakes were found to be associated with 8 major lineaments. The Mandya-Channapatna-Bangalore lineament, Lakshman Thirtha- KRS-Bangalore lineament, and Chelur-Kolar-Battipalle lineament are some of the seismically active lineaments identified in the study. Most of the earthquakes are confined to the southern part of the State indicating that south Karnataka is seismically more active. Hence, there is a need to upgrade the seismic zonation of Karnataka especially for areas surrounding Mandya, Bangalore, and Kolar. The earthquakes appear to have occurred due to movement alonglacross faults and warrant detailed study of seismically active lineaments using latest techniques like Global Positioning System (GPS), Satellite Laser Ranging (SLR), Synthetic Aperture Radar (SAR) Interferometry, and Thermal Remote Sensing.
