Sedimentational, Structural and Migmatitic History of the Archaean Dharwar Tectonic Province, Southern India
Proc. Indian Acad. Sci. (Earth Planet. Sci.), Vol. 100, No. 4, December 1991, pp. 413-433. Printed in India. Sedimentational, structural and migmatitic history of the Archaean Dharwar tectonic province, southern India K NAHA 1, R SRINIVASAN 2 and S JAYARAMa 1Department of Geology and Geophysics, Indian Institute of Technology, Kharagpur 721 302, India 2National Geophysical Research Institute, Hyderabad 500007, India aDepartment of Mines and Geology, Karnataka State, Lai Bagh Road, Bangalore,560027, India MS received 27 July 1991 Abstract. The earliest decipherable record of the Dharwar tectonic province is left in the 3-3 Ga old gneissic pebbles in some conglomerates of the Dharwar Group, in addition to the 3"3-3-4Ga old gneisses in some areas. A sialic crust as the basement for Dharwar sedimentation is also indicated by the presence of quartz schists and quartzites throughout the Dharwar succession. Clean quartzites and orthoquartzite-carbonate association in the lower part of the Dharwar sequence point to relatively stable platform and shelf conditions. This is succeeded by sedimentation in a rapidly subsiding trough as indicated by the turbidite-volcanic rock association. Although conglomerates in some places point to an erosional surface at the contact between the gneisses and the Dharwar supracrustai rocks, extensive remobilization of the basement during the deformation of the cover rocks has largely blurred this interface. This has also resulted in accordant style and sequence of structures in the basement and cover rocks in a major part of the Dharwar tectonic province. Isoclinal folds with attendant axial planar schistosity, coaxial open folds, followed in turn by non-coaxial upright folds on axial planes striking nearly N-S, are decipherable both in the "basement" gneisses and the schistose cover rocks. -
Microbiological Pollution of Air in Lal Bagh Botanical Gardens, Bangalore, Karnataka, India
International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Microbiological Pollution of Air in Lal Bagh Botanical Gardens, Bangalore, Karnataka, India Nandini .N1, Sivasakthivel S2 1 Chairperson and Principal investigator, Department of Environmental Science, Bangalore University, JB.Campus, Bangalore-56, Karnataka, India 2Department of Environmental Science, Bangalore University, JB.Campus, Bangalore-56, Karnataka, India Abstract: Bioaerosols significantly influence indoor and outdoor air quality and may cause numerous allergies and diseases. Intensity of habitual birds within the park and recreational garden exposes the visitors to elevated concentrations of bioaerosols that is mainly emitted by birds. Our study presents results of an evaluation of air quality in the Lal Bagh Botanical Garden in Bangalore. Air tests were conducted by using of impaction method at different sites of the garden and compared with Outdoor Air quality standards prescribed by Polish- European Environmental protection agency PN-89/Z-04111/02 and PN-89/Z-04111/03. The analysis indicates that bacterial pollution were the most abundant at Pigeon feeding/sheltering site and the bacterial number increased with distance of downwind. Negative rods dominated making up 45% and positive Cocci were 36% of the airborne bacterial community. Negative coccus was recorded as 13% and positive rod was recorded as 6%. Eight species of bacteria detected are Aeromonas sp., Enterococcus faecalis, Mycobacterium sp., Citrobacter sp., Pseudomonas sp., E.coli, Micrococcus, Staphylococcus sp. These pathogens may get aerosolized from Pigeon faecal matter and drops. The most abundant microorganisms in this region were fungi, the concentration of fungal number varied from 2,805 to 3,451 CFU/m3, predominating genera were Aspergillus, Fusarium and Alternaria contributed over 17%,15%,15% of all fungal genera. -

SOME PROBLEMS PERTAINING to Tile PENINSULAR GNEISSIC COMPLEX Just As in Human Affairs Where the So-Called 'Eternal Triangle'

PICHAMUTHU V~~"'\~~'i'l\,G~~\~%\~'Il\~~d~\'j ~\ ~n~\'Il, v,'IlTl%'Il\t>1~ Abstract Since the terrns Peninsular gneiss and Dharwar schist have recently been used by some writers without reference to the original meaning ascribed to them by the geologists who first coined those terms, attention is drawn here to their exact scope and significat1ce. In Karnataka, 'Peninsular gneiss' comprised all granites and gneisses except those of Closepet, Chitaldr1Jg, Hosdurga, Arsikere, Banavar, and Saulanga ; and 'Dharwar schist' included all the crystalline schists (metavo!canics and metasediments) as opposed to the felsic gneisses. peninsular gneiss was considered to be intrusive into the Dharwars No early geologist in India was entirely of the opinion that the Dharwars were youvger than the gneisses. The Bababudan Syncline contains the oldest Dharwar sequence composed of mafic and ultramafic volcanics and intrusives (some of komatiitic affinity) intercalated with iron formations. Limestones are entirely absent. The actual base of the Dharwars has nowhere been definitely proved. Vertical shafts more than 3l<m deep in the Kolar Gold Fields have not touched the bottom. 'fhe fact that in some places the schists are seen' resting on gneiss' does not mean that t)ley constitute the lowest Dharwars. A general progressive metamorphism in the schist belts in southern Karnataka can be noticed frol11 north to south, culminating in high grade granulite facies rocks. There is no field evidence which lends support to the presumption that the chamockites are overthrust on the Dharwars. -

Bangalore (Or ???????? Bengaluru, ['Be?G??U??U] ( Listen)) Is the Capital City O F the Indian State of Karnataka
Bangalore (or ???????? Bengaluru, ['be?g??u??u] ( listen)) is the capital city o f the Indian state of Karnataka. Located on the Deccan Plateau in the south-east ern part of Karnataka. Bangalore is India's third most populous city and fifth-m ost populous urban agglomeration. Bangalore is known as the Silicon Valley of In dia because of its position as nation's leading Information technology (IT) expo rter.[7][8][9] Located at a height of over 3,000 feet (914.4 m) above sea level, Bangalore is known for its pleasant climate throughout the year.[10] The city i s amongst the top ten preferred entrepreneurial locations in the world.[11] A succession of South Indian dynasties, the Western Gangas, the Cholas, and the Hoysalas ruled the present region of Bangalore until in 1537 CE, Kempé Gowda a feu datory ruler under the Vijayanagara Empire established a mud fort considered to be the foundation of modern Bangalore. Following transitory occupation by the Ma rathas and Mughals, the city remained under the Mysore Kingdom. It later passed into the hands of Hyder Ali and his son Tipu Sultan, and was captured by the Bri tish after victory in the Fourth Anglo-Mysore War (1799), who returned administr ative control of the city to the Maharaja of Mysore. The old city developed in t he dominions of the Maharaja of Mysore, and was made capital of the Princely Sta te of Mysore, which existed as a nominally sovereign entity of the British Raj. In 1809, the British shifted their cantonment to Bangalore, outside the old city , and a town grew up around it, which was governed as part of British India. -

Bangalore Today
1 2 3 In 1807 the cantonment began to emerge, and all troops from the surrounding areas were now stationed in Bangalore. Soon the Company desiring more power, removed the Wodeyar family from the administrative control of Mysore. The cantonment began to extend further west and new residential plans were laid out for the cantonment expansion. The cantonment necessitated recreational activities, so golf courses and racecourses were developed, which further extended the green belt that divided the cantonment and the Petta area. Churches were erected in different parts, which marked the early cantonment limits. The British reshaped Bangalore into an urban settlement, connected by air, rail, telegraph and telephone lines. When AFTER A SERIES of battles over nearly forty years, Bangalore was hit by the plague in 1898, a few notable Indians Bangalore finally came under the control of the East India entered the urban planning scenario and planned out new Company. The final defeat and death of Tipu Sultan in the residential layouts. fourth Anglo-Mysore war in 1799, allowed the company to enter Bangalore and expand further South. The British gave Bangalore, before it became a technological hub, was breaking the kingdom (including Bangalore) back to the Mysore ruler, new grounds in scientific research. The city became the Maharaja Krishnaraja Wodeyar III. The British resident stayed capital of the state and after the exit of the British, continued in Bangalore. Later on the Maharaja granted the Company on its way to becoming an urban metropolis, boasting of its the area around Ulsoor Lake to set up camp. green parks and abundant lakes. -
Tectonic Framework for Precambrian Sedimentary Basins in India
1 1 The Archean and Proterozoic History of Peninsular India: Tectonic 2 Framework for Precambrian Sedimentary Basins in India 3 4 Joseph G. Meert1 and Manoj K. Pandit2 5 1Department of Geological Sciences, 241 Williamson Hall, University of Florida, Gainesville, FL 32611 USA 6 2Department of Geology, University of Rajasthan, Jaipur 302004, Rajasthan, India 7 2 8 Abstract 9 The Precambrian geologic history of peninsular India covers nearly 3.0 billion years of time. The Peninsula 10 is an assembly of five different cratonic nuclei known as the Aravall-Bundelkhand, Eastern Dharwar, Western 11 Dharwar, Bastar and Singhbhum cratons along with the Southern Granulite Province. Final amalgamation of these 12 elements occurred either by the end of the Archaean (2.5 Ga) or the end of the Paleoproterozoic (~1.6 Ga). Each of 13 these nuclei contains one or more sedimentary basins (or metasedimentary basins) of Proterozoic age. This paper 14 provides an overview of each of the cratons and a brief description of the Precambrian sedimentary basins in India 15 that form the focus of the remainder of this book. In our view, it appears that basin formation and subsequent clo- 16 sure can be grossly constrained to three separate intervals that are related to the assembly and disaggregation of the 17 supercontinents Columbia, Rodinia and Gondwana. The oldest Purana-I basins developed during the 2.5-1.6 Ga in- 18 terval, Purana-II basins formed during the 1.6-1.0 Ga interval and the Purana-III basins formed during the 19 Neoproterozoic-Cambrian interval. 20 21 Introduction 22 Peninsular India represents an amalgam of ancient cratonic nuclei that formed and 23 stabilized during Archaean to Paleoproterozoic (3.8-1.6 Ga).
