  • Hydrothermal Alteration at the Lonar Lake Impact Structure, India: Implications for Impact Cratering on Mars

    Hydrothermal Alteration at the Lonar Lake Impact Structure, India: Implications for Impact Cratering on Mars

    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.

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.

Mullenbach Wilford D. Gardner Committee Members, Mary Jo Richardson Head of Department, Robert R. Stickney August 2007 Major Subject: Oceanography iii ABSTRACT Suspended Sediment Transport in the Ganges-Brahmaputra River System, Bangladesh. (August 2007) Stephanie Kimberly Rice, B.S., The University of Mississippi Co-Chairs of Advisory Committee: Dr. Beth L. Mullenbach Dr. Wilford D. Gardner An examination of suspended sediment concentrations throughout the Ganges- Brahmaputra River System was conducted to assess the spatial variability of river sediment in the world’s largest sediment dispersal system. During the high-discharge monsoon season, suspended sediment concentrations vary widely throughout different geomorphological classes of rivers (main river channels, tributaries, and distributaries). An analysis of the sediment loads in these classes indicates that 7% of the suspended load in the system is diverted from the Ganges and Ganges-Brahmaputra rivers into southern distributaries. Suspended sediment concentrations are also used to calculate annual suspended sediment loads of the main river channels. These calculations show that the Ganges carries 262 million tons/year and the Brahmaputra carries 387 million tons/year.

Raitt, and Frans J. Emmel, Scripps Institution of Oceanography, La Jolla, California ABSTRACT Two drilling sites were proposed in the Bay of Bengal (Sites 217 and 218) in areas of anomalously thin section as determined by earlier seismic work. Although possibilities for characterizing the sediments in the normal thick section of the Bengal Fan were precluded, these holes were, nevertheless, successful in determin- ing the ages of two unconformity-refracting horizons which had been traced throughout the entire bay. These horizons, which subdivide the sedimentary section into three units, probably mark times of both plate-edge and mid-plate deformation. The oldest sediments in the Bay of Bengal were deposited on new sea floor formed after rifting of India from Antarctica and Australia, probably as a Cretaceous and Paleocene passive continental rise up to 12 km thick. First collision of India with the subduction zone lying off the southern margin of Asia occurred at the end of the Paleocene, causing both uplift of ancestral mountains in the eastern Himalayan region and defor- mation and unconformity across the bay. The first phase of Bengal Fan deposition was from middle Eocene into uppermost Miocene. At this time important further tectonism occurred, causing uplift of the modern Himalayas, deformation of the sea floor, and changes in sedimentation in the bay. Subsequent deposits of the modern Bengal Fan are largely undeformed. INTRODUCTION unconformably on apparently older deformed fan and pelagic deposits, and these in turn unconformably overlay The international Indian Ocean expeditions of 1960 to still older deposits of unknown origin.
