Résumé :
The ground magnetic field of the Lonar impact crater (Maharashtra State, India) and its surrounding area was measured and studied utilizing 2.5-dimensional potential field modelling. Field data showed the crater depression is associated with a strong circular negative anomaly with an amplitude of more than 1000 nT. The negative anomaly, however, decreases smoothly while moving from south to north. Most of the crater rim exhibits anomalous positive values. Negative anomalies at the rim are seen in the south–southwestern sections and coinciding in the northeastern section with the Dhar valley. Our study shows that most of the anomaly is caused by the topographic effect and a strong SE directed natural remanent magnetization of Deccan Trap basalts, which are the target of the Lonar-creating projectile. The magnetic anomaly of the relatively weakly magnetized impact-produced allochthonous breccia and post-impact sediments is small, being less than 150 nT.

Résumé :
A thesis submitted to the University of Mumbai for the Ph.D.(Science) degree in Physics under the guidance of Prof. Nathani Basavaiah.
Conclusion summarized under topics : Structural and Anisotropy of Magnetic Susceptibility (AMS) evidence for oblique impact at Lonar, Distribution of impact-induced stress with the direction of Lonar impact, Rock magnetic study of Lonar basalts, Rock magnetic study of Ramgarh magnetic particles, Palaeomagnetic study of Lonar basalts, Rock- and Palaeo-magnetic study of randomly oriented ejecta blocks from Lonar, Geochemistry of rocks from Lonar and Ramgarh crater IMPACT CRATERING RESEARCH IN INDIA AND FUTURE DIRECTIONS This study provides invaluable data in the investigation of natural impact craters in India; it suggests that Lonar and Ramgarh samples provide new data to study the magnetic field phenomena associated with the impact craters. From the investigation of magnetic study, it is inferred that a relationship exists between an oblique impact from the east at Lonar and geological structural variations around the crater rim. This work provides a useful tool in understanding the obliquity of impacts for small craters of terrestrial and extraterrestrial examples. Additionally, this work draws our attention on impact cratering research for searching new craters in the Indian shield. Incidentally, Radhakrishna (2005) proposed to reexamine circular to semi-circular morphology from impact cratering research view point in different parts of India: (i) the Cuddapah basin, (ii) the tectonic group of islands off the coast of Mumbai, and the islands of Saurashtra and Kachchh, (iii) the regions of Malani, and (iv) Simlipal complex, Odisha. The reported magnetization mechanism of shocked and unshocked basalts as a method of characterizing samples helped in advancement of knowledge in the field of impact cratering in order to understand the shock-induced magnetization effects on target lithologies and to investigate their structural deformation, emplacement mode and post-impact alterations. Initial rock magnetic and palaeomagnetic data of Ramgarh structure partly confirmed its origin by asteroid impact; it suggests that the Ramgarh impact crater is only weakly magnetic. This kind of geophysical magnetic investigation can be extended further to explore the Dhala and Luna impact crater structures in the Indian subcontinent. In such investigations, the present work is expected to be an initial platform to furtherance of a multi-disciplinary application to impact cratering processes using both magnetic and advanced techniques such as Fourier Transform Infrared (FTIR) spectroscopy, XRD, scanning electron microscope (SEM) and geochemical analysis. It is hoped that the impact cratering research will become popular among geoscientists in India, so that adequate trained manpower will be available for future space missions to the Moon and Mars.

Texte intégral
Résumé :
Impact cratering and aqueous alteration are two important processes that have modified the Earth’s surface over time and better understanding of these processes on Earth allow us to understand the surface evolution of other planetary bodies in the inner solar system. This thesis focuses on the study of terrestrial analogues and can be divided into two parts: the first part deals with the study of two terrestrial impact craters, namely Lonar and Dhala from India, and the second part deals with the formation of a unique aqueous alteration product called jarosite. The 1.8 Km diameter Lonar impact crater, hosted on the Deccan basalts formed ~0.5 Ma ago and is one of the best-preserved terrestrial impact craters on basalt. The impactor is rarely preserved at the cratering site because the impact process results in large-scale melting and vaporization. However, the products of impact cratering preserve information related to the cratering process. Chemical and isotopic compositions of the sub-mm sized impact spherules, collected from surface sediments near the south-eastern rim of the Lonar crater, were used to understand the cratering process at Lonar. High Ir and Cr concentrations in some of these spherules suggest 1-8 wt% contribution of a chondritic impactor at Lonar. Enrichment of the light rare earth elements (LREE) and large ion lithophile elements (LILE) in some other spherules and impact breccia samples, supported by Nd and Sr isotopic compositions of some of these samples, suggest up to 15 wt% contribution of the sub-basaltic granitic basement, which melted upon impact. Concentrations of relatively volatile elements like Cu and Zn in the Lonar spherules show evidence of volatile loss during impact, as well as re-condensation from a volatile-rich part of the vapor plume. The chemical heterogeneity observed in the Lonar spherules was further investigated by studying the morphology of spherules and non-spherical impact glasses (NSIG) using X-ray Micro-computed tomography. The results suggest that the smallest spherules (< 200 microns diameter) are more likely to preserve the impactor signature while the NSIG’s, are more likely to preserve the signatures of the sub-basaltic granitic basement. As part of this study, a second impact crater with contrasting features compared to the Lonar crater was studied. The 11 Km diameter Dhala impact crater is hosted on the Bundelkhand granite. The heavily eroded nature of the crater suggests that it formed a long-time ago and its age estimates range from 2.4 – 2.2 Ga, making it a rarely preserved example of a large crater formed in the Proterozoic. It is a complex crater with a central elevated area (CEA), which is the only well-preserved feature of this crater. The Nd isotopic compositions of the sedimentary rock samples from the CEA suggest that they belong to the Lower Vindhyan Supergroup. The Ni/Cr and Ni/Co ratios, measured in the melted and brecciated granite samples, suggest a chondritic impactor at Dhala. In addition, these rocks show evidences of alteration by a potassium-rich fluid. Strontium and Ca isotopic compositions of the melt breccia have been used to place chronological constraints on the alteration event by a K-rich fluid, which most-likely took place ~1.8 Ga ago. If this alteration event is related to the hydrothermal alteration that immediately follows an impact cratering event, it is possible that the formation age (2.4-2.2 Ga) for the Dhala impact crater has been over-estimated. The second part of this thesis investigates the origin of the mineral jarosite at Kutch, India. This mineral, widely reported on the surface of Mars, is an endmember of the hydroxy-sulfate mineral group, forms at low pH and high Eh conditions, and under specific water:rock ratios. The jarosites at Kutch are considered as a martian analog because of their spatial proximity with the Deccan basalt. Geochemical compositions of the hydroxy-sulfates from Kutch, collected from multiple stratigraphic sections, show clear signatures of precipitation from a sulfate-rich acidic fluid. Combined Nd and S isotopic compositions suggest that the low pH of the fluid is derived from weathering of pyrite while combined Sr and S isotopic compositions suggest that the source of the fluid, from which the hydroxy-sulfates precipitated at Kutch, is seawater. The 87Sr/86Sr and δ34S compositions of seawater over time have been used to constrain the age of the hydroxy-sulfates at Kutch to less than 20 Ma, which is much younger than the formation of the ~ 65 Ma old Deccan basalt. The inferred time of formation of the Kutch jarosites coincides with the timing of widespread aridity in other parts of the world.

Résumé :
ABSTRACT Rampart craters are omnipresent features on volatile-rich solid planetary surfaces. This raises the question whether, and how many, rampart craters are present on Earth. We reviewed the terrestrial impact crater record with regard to possible rampart morphologies and present detailed morphological analyses of these terrestrial craters here. Our results show that the Ries crater in Germany, Bosumtwi crater in Ghana, Tenoumer crater in Mauritania, Lonar crater in India, and Meteor crater in the United States are terrestrial rampart craters. The Ries and Bosumtwi craters can be classified as double-layer ejecta (DLE) craters, whereas Tenoumer, Lonar, and Meteor craters can be classified as single-layer ejecta (SLE) craters. Tenoumer and Meteor craters show rampart as well as common lunar-like ejecta characteristics within their ejecta blankets and, thus, appear to be hybrid craters. In addition, we discuss seven crater structures that show at least some morphological or lithological peculiarities that could provide evidence for possible ejecta ramparts. Considering the low number of terrestrial impact craters with well-preserved ejecta blankets, the relatively high proportion of rampart craters is astonishing. Obviously, the formation of layered or rampart craters is a common and not a rare process on Earth.
