“…The researchers can get information from the geological study on which approach is related to ancient weathering, including complete geological formation, and also represent frequent weathering profiles (Turkington & Paradise, 2005). According to Indu et al (2022), these profiles are much thicker and have a dominant imprint of geochemical signatures along with palaeo‐climatic proxies was seen more prominently than in present landscapes. Risk evaluations have been performed by several researchers using GIS (Yuan, Ying, et al, 2018).…”

Climate change has an effect on ecosystems and people all around the globe and causes land degradation. A long‐term decline in biological output, loss of ecological integrity, and a fall in the economic worth of the land are all signs of “land degradation”, a downbeat trend in land condition. In the red lateritic zone of the tropical area, where “climate change” and “land degradation” are related, they impact one another. On the other hand, due to the emissions of greenhouse gases (GHGs), which slow the rate of carbon absorption, and the extent of various existing land degradation processes, which are worsened in pace and magnitude by “climate change”. The world's expanding population poses a challenge to supplying the rising demand for food in recent decades. The need for additional land for farming, feed, and other forms of production is fuelled by poverty and the destruction of the environment. In tropical regions, “soil erosion” caused by “water and wind, salinization and alkalinity, acidity, losses of organic carbon, nutrient imbalance, pollution/contamination by toxic substances, and soil sealing and capping” all call for immediate action to stop the land degradation process and sustainably restore productivity for environmental security and food security for the world's expanding population. After fulfilling the requirement systematic knowledge about soil, scientific use of natural resources (water, land, minerals, vegetation, air and biodiversity) will present a healthy planet with a healthy ecological system for future generations.

“…Fredriksson et al ( 1973a ) were the first to carry out a detailed study at Lonar describing the geochemistry of glassy fragments while drilling the Lonar crater floor. Lonar can be considered as one of the most extensively studied simple impact craters in the world, encompassing geochronology (Sengupta and Bhandari, 1988 ; Sengupta et al, 1997 ; Storzer and Koeberl, 2004 ; Jourdan et al, 2011 ; Nakamura et al, 2014 ; Rao and Bhalla, 1984 ; Maloof et al 2010 ), geomorphological characterisation (Fudali et al 1980 ; Maloof et al, 2010 ; Indu et al, 2022 ), ejecta emplacement characterisation (Maloof et al, 2010 ; Kumar et al, 2014 ), mineralogy (Schaal et al 1976 ; Kieffer et al, 1976 ), geochemical characterization of the target basalt rocks, and impact derivatives like melt rocks, glasses, and spherules (Nayak 1972 ; Fredriksson et al, 1973a , 1973b ; Kieffer et al, 1976 ; Morgan 1978 ; Stroube et al, 1978 ; Osae et al, 2005 ; Son and Koeberl, 2007 ), projectile characterisation (Misra et al, 2009 ; Schulz et al, 2016 ; Gupta et al, 2017 ; Ray et al 2017 ), involvement of basement rock (Chakrabarti and Basu 2006 ; Schulz et al, 2016 ; Chandran et al, 2021 ), geophysical studies (Fudali et al, 1980 ; Kumar et al, 2014 ; Sivaram et al, 2018 ), hydrological properties of surrounding rocks (Komatsu et al, 2014 ), structural characterisation (Kumar 2005 ; Misra et al, 2010 ), spectral studies of target rocks (Wright et al, 2004 ; 2011 ), and magnetic properties (Rao and Bhalla, 1984 ; Louzada et al, 2008 ; Weiss et al, 2010 ; Misra et al, 2010 ; Arif et al, 2012 ; Agarwal et al, 2016 ).…”

“…Impact craters were known to humankind when the remotely sensed images of the Moon, dotted with tens of thousands of basin-like structures (called craters), were captured. This provided the impetus for studying craters on Earth, which not only led to the identification of several craters but also unraveled a plenitude of geological processes that were triggered or evolved through meteoritic impacts (Li et al, 2018;Keerthy et al, 2019;Chandran et al, 2021;James et al, 2021James et al, , 2022Aneeshkumar et al, 2021Aneeshkumar et al, , 2022Indu et al, 2022). Impact events are linked to the possibility of the origin of life (McKay et al, 1996), mass extinction (Alvarez et al, 1980), the evolution of Moon (Daly 1946;Canup and Asphaug, 2001), and even the initiation of plate tectonics on Earth (Maruyama et al, 2018;Santosh et al, 2017;Maruyama and Santosh, 2017).…”

Lonar Impact Crater, India: the Best-Preserved Terrestrial Hypervelocity Impact Crater in a Basaltic Terrain as a Potential Global Geopark

Lonar Impact Crater is a simple meteorite impact crater carved out on the ~ 65 Ma old Deccan tholeiitic flood basalts. The crater, though scoured in a basaltic terrain, is still preserved in its most pristine form, with a central crater lake. The geomorphology, geochemistry, geochronology, hydrology, geophysical parameters, and structural aspects of Lonar Crater have been explored in detail, but still continue to contribute valid scientific insights into the geology of terrestrial impact craters. Lonar serves as a potential analog site for studying impact cratering on planetary surfaces with basaltic terrains such as the Moon and Mars. Besides being a highly recognizable impact crater in India, the Lonar crater and its hinterland stand out with its archeological relevance and spiritual influence among the people. The numerous temples in and around the crater premises uphold the cultural significance of the region. The crater and adjacent areas are rich in flora and fauna representing a diverse ecosystem in the vastness of the arid Deccan Flood Basalts. Hence, the astrobleme and its surrounding is declared a Ramsar site and is also a protected wildlife sanctuary. The Indian Government has also declared the crater a National Geological Monument as well as an archaeological monument. Furthermore, the astrobleme is a unique site with socio-cultural and economic significance. With these plethoras of importance, combined with the geological and socio-cultural aspects in its hinterland, together with the most acclaimed UNESCO world heritage centers Ajantha and Ellora caves in the neighborhood, it stands as the right candidate for a UNESCO Global Geopark. However, the crater and its ecosystem are not preserved well enough, and the uniqueness of the crater is diminishing. But after selection as a Ramsar site, the area shows increased vegetation growth. The SWOT analysis conducted in this study accounts for Lonar Crater and its adjoining areas as a potential global geopark. Thus, through this study, we try to propagate the vivid and myriad importance of the Lonar crater and the necessity of protecting this geological monument from both anthropogenic and natural processes and to appraise the necessity for nominating this area as a UNESCO Global Geopark.

In contrast, the other inner planetary bodies of the solar system, where active geological processes like plate tectonics do not occur, preserve ample evidence of impact cratering with hundreds of thousands of impact craters sprinkled across (Chandran et al, 2021;French & Koeberl, 2010;Indu et al, 2021;James et al, 2022;Keerthy et al, 2019;Li et al, 2018;Maloof et al, 2010).…”

Terrestrial impact craters track the voyage of lithospheric plates

The paradigm of plate tectonics has aided in the identification of the journey of continents on the globe, their assembly into supercontinents, disruption, and re‐assembly. Here, we use meteorite impact craters as proxies for tracking the voyage of lithospheric plates. Employing the provisions in GPlates, an interactive geographic information system‐based plate tectonic reconstruction model, we were able to identify the palaeo‐position, and velocity of the 174 terrestrial impact craters, formed after 1,100 Ma, across the globe. These parameters of craters were evaluated for independent tectonic plates and were correlated with global tectonic events. For example, the similarity in the velocity of Beaverhead (900 Ma) and Holleford (550 Ma) craters since 550 Ma is traced to the connection between the Eastern Basin and North America Craton commencing 1,100 Ma, and through the South Basin and Range. Likewise, the drastic reduction in the velocity of Spider Crater (700 Ma) in Australia after 600 Ma can be attributed to the subduction between east and west Gondwana. The accelerated motion of the Indian Plate at 63 Ma, when the lithosphere was hovering over the Réunion hotspot, is also explained. With the advent of more improved plate tectonic models and the discovery of more impact craters, improvised interpretations will be possible.
