College of Science, Aurangabad S.B.E.S. College of Science, Aurangabad [email protected] [email protected] Abstract The impact origin of the Lonar crater has been well established based on the evidence of shock metamorphosed material. An attempt has been made to evaluate physicochemical qualities of Lonar Lake water. Water samples were analyzed from 2012 to 2013 for seasonal variation in physicochemical qualities of Lonar lake water and revealed that, the water is alkaline (pH 10.5) and characterized by high concentration of Alkalinity (5786 mg/L), Sulphate (67 mg/L), Magnesium (1043 mg/L), Chloride (2816 mg/L) and Dissolved Oxygen (0.03 mg/L). The data indicated that the alkalinity is increased in monsoon and post-monsoon season while decrease in pre-monsoon season. Likewise the chloride and salinity is increased in pre monsoon season while decreased in monsoon and post-monsoon season. As the Lonar Lake is unique in the world for its alkalinity and salinity of the water but its alkalinity, pH and salinity goes on decrease day by day. Hence this World heritage should be preserved for its alkalinity and salinity. Occurrence of few species of algae and fungi indicate the characteristics nature of bio-flora, which needs further investigation and interpretation Keywords: Lonar Crater, Physico-chemical quality. 1. INTRODUCTION: Lonar Lake (19°58' N; 76°31' E) in Buldhana district, Maharashtra, India is a circular lake occupied by saline water (Fig.1.) It is formed by hypervelocity meteoritic impact in basalt rock of the Deccan Traps near about 50 thousand years ago. It‟s diameter about 1830 m. and depth is 135 m. The lake is confined from all sides by crater rim of the crater a not a single channel of water for drainage out. The water is stagnant for thousands years. The water is salty, alkaline and the lake is rich with various biotic and abiotic assemblages. It offers unique opportunities for ecological investigation.

MATERIALS AND METHODS: Water samples were collected from four different sampling stations in airtight and opaque polythene container. These four stations are located in reservoir such as 1) Sampling station „A‟ water from Ramgaya (East), 2) Sampling station „B‟ water from Lord Shiva Temple (West), 3) Sampling station „C‟ water from Shani Temple (South) and 4) Sampling station „D‟ water from Devi Temple (North) was established along the periphery of lake basin for one year limnological study programme. Standard analytical methods were employed to analyse water samples of Lonar lake (APHA, 1989) Microbiological examinations were carried out using the standard procedures given by (APHA, 1989, Trivedy and Goel, 1986, Kale and Bhusari, 2001) and the result were compared with maximum permissible was carried out by conducting MPN, SPC and iMVIC tests. Methods of Sampling of Microorganisms: I) Collection: Algal blooms and water samples were collected in and around four different spot in vicinity of Lonar Lake. II) Culture media used: The media employed for isolation of Spirulina sp. in Zarrouk media with pH 10.5 Zarrouk medium. 3. RESULTS AND DISCUSSION: The present paper deals with water quality parameters and micro-ecological aspects of Lonar Lake. The result of four sample stations and comparative data of other researchers are given in Table. 2 Temperature of lake water ranged from 23.6 to 24.4, which varies with respect to depth season and environment. The depth of water varies at different places. All these characteristics of Lake resulted into an extreme alkaline ecosystem with all different microbial type prevailing in and around the Lake.

Plate 1 to Plate 6, Plate-7 and Plate-8) Lonar Lake is a hyper saline environment due to present of higher concentrations of various salts in lake water (Muley and Babar, 1998; Choudhary and Handa, 1978). The characterized salt concentration could be major reason of predominant population of cyno-bacteria such as Oscillatoria, Synechocystis, Anabaenopsis and Spirulina in the lake. It is confirmed that the cyno-bacteria population is regulated by the concentration of salts and alkalinity. The colour of Lake water is yellowish green to dark green which results dense algal population the pH of water sample was found to be alkaline which ranged between 7.2 to 11.2 the higher values of pH may be due to the increased primary production in aquatic ecosystem of lake ( Zafar,1996 and Mohd. Mussaddiq et. al., 2001) Low rate of primary production in aquatic ecosystem of lake is also indicate by the low values BOD and COD that ranged from 0.1 to 0.3 mg/lit. and 0.01 to 0.04 mg/liter respectively. The BIS (1991) Maximum permissible limit of (TDS) Total Dissolved Solid is 1500 mg/liter for drinking water. The TDS in study area ranged from 8900 mg/liter to 12460 mg/liter which is very high and above the permissible limit of BIS (1991). The chloride concentration in the lake varies from 55.5 mg/liter to 2816 mg/liter which is above the permissible limit of 250 mg/liter as given by BIS (1991) this means that the water is pollution due to organic matter and the other waste in the water.

    Meteoritics & Planetary Science 38, Nr 3, 365–381 (2003) Abstract available online at http://meteoritics.org Hydrothermal alteration at the Lonar Lake impact structure, India: Implications for impact cratering on Mars Justin J. HAGERTY* and Horton E. NEWSOM Institute of Meteoritics, Department of Earth & Planetary Sciences, University of New Mexico, Albuquerque, New Mexico 87131, USA *Corresponding author. E-mail: [email protected] (Received 12 June 2002; revision accepted 20 February 2003) Abstract–The 50,000 year old, 1.8 km diameter Lonar crater is one of only two known terrestrial craters to be emplaced in basaltic target rock (the 65 million year old Deccan Traps). The composition of the Lonar basalts is similar to martian basaltic meteorites, which establishes Lonar as an excellent analogue for similarly sized craters on the surface of Mars. Samples from cores drilled into the Lonar crater floor show that there are basaltic impact breccias that have been altered by post-impact hydrothermal processes to produce an assemblage of secondary alteration minerals. Microprobe data and X-ray diffraction analyses show that the alteration mineral assemblage consists primarily of saponite, with minor celadonite, and carbonate. Thermodynamic modeling and terrestrial volcanic analogues were used to demonstrate that these clay minerals formed at temperatures between 130°C and 200°C. By comparing the Lonar alteration assemblage with alteration at other terrestrial craters, we conclude that the Lonar crater represents a lower size limit for impact-induced hydrothermal activity. Based on these results, we suggest that similarly sized craters on Mars have the potential to form hydrothermal systems, as long as liquid water was present on or near the martian surface.

    CHAPTER – 3 DRAINAGE PATTERN The word 'Drainage' means flow of water. If you look at the physical map of India, you will find that small streams that flows in different areas combine together to form a major river. In the end, these rivers discharge themselves in large water bodies like Lake or Sea or Bay. The water of a region that flows through a river system is called drainage basin. When a highland, e.g., Mountain, separates two neighbouring drainage basin then this type of highland is called 'Water Divide'. The development of any drainage pattern is determined by the topography of that particular region. The rivers of India can be divided into two parts on the basis of land forms: 1. Rivers of Himalayas 2. Peninsular Rivers As these rivers originate in different geographical regions, they are different from each other. Their difference is evident from the following description: DO YOU KNOW? RIVERS OF HIMALAYAS Amazon river basin is the Most of the Himalayan rivers are largest drainage basin of the perennial. Apart from rainfall, these World. rivers continuously receive supply of FIND OUT water, all the year round, by the melting Which river has largest snow on the peaks of the Mountains. drainage basin in India? Rivers like Indus and Brahmaputra originate from Himalayas. These rivers have cut down the Mountains to form gorges during the course of their flow (Fig. 3.1). The rivers originating from Himalayas, right from their origin point to their journey up to the Sea, they perform several functions. On the upper parts of their course they cause massive erosion and carry with them loads of eroded materials like silt, sand, soil, etc.

  • Indian Monsoon Variations During Three Contrasting Climatic Periods: the Holocene
    Indian monsoon variations during three contrasting climatic periods: the Holocene, Heinrich Stadial 2 and the last interglacial-glacial transition Corresponding Email : [email protected] Keywords: Indian summer monsoon; Core Monsoon Zone; pollen assemblage; Holocene, Heinrich Stadial 2, last interglacial-glacial transition In contrast to the East Asian and African monsoons the Indian monsoon is still poorly documented throughout the last climatic cycle (last 135,000 years). Pollen analysis from two marine sediment cores (NGHP-01-16A and NGHP-01-19B) collected from the offshore Godavari and Mahanadi basins, both located in the Core Monsoon Zone (CMZ) reveals changes in Indian summer monsoon variability and intensity during three contrasting climatic periods: the Holocene, the Heinrich Stadial (HS) 2 and the Marine Isotopic Stage (MIS) 5/4 during the ice sheet growth transition. During the first part of the Holocene between 11,300 and 4,200 cal years BP, characterized by high insolation (minimum precession, maximum obliquity), the maximum extension of the coastal forest and mangrove reflects high monsoon rainfall. This climatic regime contrasts with that of the second phase of the Holocene, from 4,200 cal years BP to the present, marked by the development of drier vegetation in a context of low insolation (maximum precession, minimum obliquity). The historical period in India is characterized by an alternation of strong and weak monsoon centennial phases that may reflect the Medieval Climate Anomaly and the Little Ice Age, respectively. During the HS 2, a period of low insolation and extensive iceberg discharge in the North Atlantic Ocean, vegetation was dominated by grassland and dry flora indicating pronounced aridity as the result of a weak Indian summer monsoon.

E-mail: [email protected] (Received 01 February 2005; revision accepted 16 July 2005) Abstract–The Lonar crater, India, is the only well-preserved simple crater on Earth in continental flood basalts; it is excavated in the Deccan trap basalts of Cretaceous-Tertiary age. A representative set of target basalts, including the basalt flows excavated by the crater, and a variety of impact breccias and impact glasses, were analyzed for their major and trace element compositions. Impact glasses and breccias were found inside and outside the crater rim in a variety of morphological forms and shapes. Comparable geochemical patterns of immobile elements (e.g., REEs) for glass, melt rock and basalt indicates minimal fractionation between the target rocks and the impactites. We found only little indication of post-impact hydrothermal alteration in terms of volatile trace element changes. No clear indication of an extraterrestrial component was found in any of our breccias and impact glasses, indicating either a low level of contamination, or a non-chondritic or otherwise iridium-poor impactor.
