“…There are two schools of thought on the formation of CEA. One is the erosion of primary crater fill sediments (Keerthy et al 2019) and the other of much later sedimentary deposits (Pati et al 2008). Neither of the two suggestions for the formation of the CEA links it to the cratering process.…”

“…The origin of the CEA is not yet clear. While Pati et al (2008) suggest that the CEA deposited on the eroded peneplain of the Dhala crater and constitutes post-Dhala rock types; Keerthy et al (2019) argue that the CEA is a vestige of denudational processes acting on the Proterozoic sediments within the crater. This discrepancy has led to arguments and ambiguity on the size of the Dhala crater, 11 km argued by Pati et al (2008) and 3 km suggested by Keerthy et al (2019).…”

The central elevated area is a postimpact morphological landmark in the otherwise flat eroded remnant of the Dhala impact structure, India. Its base is the Bundelkhand granitic complex followed by beds of Dhala and Kaimur Formations. The beds of the Dhala and Kaimur Formation present typical sedimentary textures and structures such as cross-bedding. The grains are angular, sorting is moderate to poor, and brittle-ductile deformation of the protolith is still preserved in some grains. This reveals a short distance of transport. Detailed microscopy and U-stage measurements confirm planar deformational features (PDFs) oriented (0001) and {10-13} in few quartz grains. Based on these facts, it is suggested that the quartz with PDFs was shocked, ejected out of the crater, and deposited near the crater cavity. Reworking of the ejecta blanket redeposited these quartz grains to their present location. Relatively few shocked grains in the rocks favor a postimpact fluvial process over impact resurge.

Modeling and Simulation Research of Wind Energy Heat Pump Direct Heating System Based on Geographic Information System

In order to ensure the normal heating of residents during the heating season in my country, with the increase of the air extraction volume of the cogeneration unit, the power generation also exceeds the use demand, so that the poor quality wind power will be forced to give up during the peak shaving of the power grid. The aggravation of coal-fired pollution also leads to a waste of energy. The use of wind-driven compression heat pumps to run heating reduces energy and capital waste. Taking into account the volatility and instability of wind energy itself, the heating technology of WEHPDHS is one of the effective ways to achieve renewable clean energy heating in severe cold regions. In this paper, a simulation model of the wind energy heat pump direct heating system(WEHPDHS) is established, and the simulation experiment is carried out on the use of the model. The geographic information system is used to collect the wind speed data under the working condition, and the variation characteristics of the system energy parameters and the energy efficiency coefficient of the mechanical energy of the wind turbine are analyzed under the variable wind speed condition. COP, and then compared the performance coefficients of different heating methods to verify the high heating efficiency of the system in this paper and the high benefits in environmental protection.

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.
