Shiva Crater
The Shiva crater is the claim by paleontologist Sankar Chatterjee and colleagues that the Bombay High and Surat Depression on the Indian continental shelf west of Mumbai, India represent a impact crater, that formed around the Cretaceous-Paleogene boundary. Chatterjee and colleagues have claimed that this could have contributed to the K-Pg extinction event. Other scholars have questioned the claims, finding that there is no evidence of an impact structure. Arguments Chatterjee argues that the Shiva crater was formed around 65 million years ago, about the same time as a number of other impact craters and the Cretaceous–Paleogene extinction event (Cretaceous–Paleogene boundary / K-Pg boundary). Although the site has shifted since its formation because of sea floor spreading, the formation is approximately long by wide. If its status as an impact crater is ever confirmed, the Shiva crater would be the largest known impact crater on Earth. It is estimated that this prop ...

Chicxulub Crater
The Chicxulub crater () is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore near the community of Chicxulub, after which it is named. It was formed slightly over 66 million years ago when a large asteroid, about in diameter, struck Earth. The crater is estimated to be in diameter and in depth. It is the second largest confirmed impact structure on Earth, and the only one whose peak ring is intact and directly accessible for scientific research. The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatán Peninsula during the late 1970s. Penfield was initially unable to obtain evidence that the geological feature was a crater and gave up his search. Later, through contact with Alan R. Hildebrand in 1990, Penfield obtained samples that suggested it was an impact feature. Evidence for the crater's impact origin includes shocked quartz, a gravity anomaly, and tekt ...

Ramgarh Crater
Ramgarh crater, also known as ''Ramgarh structure'', ''Ramgarh Dome'' and ''Ramgarh astrobleme'', is a meteor impact crater of diameter in Kota plateau of Vindhya range located adjacent to Ramgarh village in Mangrol tehsil of Baran district in Rajasthan state of India.

Luna Crater
Luna crater is an impact crater at Luna village in Bhuj taluka of Kutch district of Gujarat, India. The crater is located in a low-lying, soft, flat area and appears unconventional and deceptive when compared to other craters in India, which are usually found on hard, rocky surfaces. Description Rock fragments and glasslike materials found at the site indicate a meteorite impact, the date of which has tentatively been put at around 2000 BCE. The crater, located in the Rann of Kutch, is circular, with a diameter of , and its lowest point is only about above sea level. Crater is visibly a kilometre wide, but the satellite radar imagery shows it is spread over a five kilometres radius. Since it lacks the characteristics of a typical impact site, it is a unique site in the world, it has a very low depth to diameter ratio. A round lake of 1 km2 in area and 2 meter in depth lies in the centre of crater, which remains dry during summers. Crater depression is covered with thi ...

Gerta Keller
Gerta Keller (born 7 March 1945) is a geologist and paleontologist who contests the Alvarez hypothesis that the impact of the Chicxulub impactor, or another large celestial body, directly caused the Cretaceous–Paleogene extinction event. Keller maintains that such an impact predates the mass extinction and that Deccan volcanism and its environmental consequences were the most likely major cause, but possibly exacerbated by the impact. Early life and education Keller was raised in Switzerland on a dairy farm, the sixth of 12 children. She grew up in poverty. In the one-room schoolhouse where she was educated, boys were given training in math and science while girls were taught cooking and cleaning, the skills they would need to be proper housewives. Her hunger for knowledge led her to read the textbooks assigned to her elder siblings, and she would prepare summaries of the material for her brothers and sisters. She attended a vocational school starting at age 14 and learned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
