A surprising new discovery of the Jinlin crater in Southern China is clarifying how celestial objects collide with Earth.
The study published in the journal Matter and Radiation at Extremes demonstrated the intriguing discovery of the Jinlin crater which helps to better understand how an impact on a hillside had been preserved within a thick granite weathering crust.
It is located in Zhaoqing, Guangdong Province, China.
Meanwhile this discovery shows that it is one of only about 200 identified craters known globally.
However, the features indicating abrasion are likely formed during the early to mid-Holocene, which began about 11,700 years ago.
In this connection, Ming Chen said, “This discovery shows the scale of impacts of small extraterrestrial objects on Earth in the Holocene is far greater than previously recorded.”
The research study suggests that the small impactor was seen as a meteorite rather than a comet which would have left a crater at least 10 kilometers wide.
It has been observed later that the team has not yet identified whether the meteorite was made of iron or stone.
The crater is particularly well preserved, especially given the heavy rainfall, humidity, and conditions that intensified erosion.
The findings have further revealed that Jinlin crater in Southern China leads to the conclusion that Earth has faced a higher and more constant risk of impact from extraterrestrial objects than previous figures estimated.
Nonetheless, it helps to better understand the frequency and scale of medium-sized events and the historical footprints of these impacts at varying rates; this makes the discovery of Jinlin Crater significant to the study of the recent geological past.
