Scientists find the fallen star’s impact location at last – a crater formed by the slamming of a meteor into the Earth from 800,000 years ago. It took some time to make the discovery, but here it is now.
Decades ago, a meteor collided onto the massive space called Earth with such potency and intensity that it covered 10 percent of the earth with a thick layer of shiny or burnished little black lumps which were made of debris of rocks.
These lumps of rock debris are famously known as tektites. What are tektites? They are tiny and glossy black materials that are recovered in large numbers over a space impacted by the crashing of a meteorite which, also, gets scattered widely through the air. These were untidily spread across Indochine to the eastern part of Antarctica and across the path of the Indian Ocean to the western portion of the Pacific Ocean.
It is no secret that scientists had been searching for the confirmation of the collision, that is, the aforementioned blemishes on the planet, but after being elusive for over a century, these globules or pellets have been found and verified.
What the group of genius minds has reported in the recent study is that the corroboration of the ancient slamming, that is, the crater was kept out of sight by a sphere of volcanic lava that dispersed over about 2,000 square miles. They knew that the crater was somewhere on the Bolaven Plateau, but the proof stayed hidden for long.
According to an authentic source, when a meteor or a streak of light that is formed when an asteroid or a meteoroid crashes onto the earth with a significantly high speed, then, the rocks around the site of the aftermath become tektites after being liquified due to the extreme heat and then cooled. They begin to glow and the presence of tektites in quite an abundance leads the scientists to realize the location of the impact even if the crater is not visible.
Though scientists spent decades thoroughly scrutinizing disconcertingly for the impression of the crater, but since the glossy tektites were present in such a widespread manner with the earlier measurements of crater varied and cradles between 9 miles diameter and 186 miles. It became difficult to tell a precise location. It has been truly established that the force was so high that there occurred a rim which is an upper edge of the object, that is, meteorite which was about 300 feet long.
Throughout the research period, the scientists discovered some potential crater candidates in the southern portion of China, the central part of Laos and northern focal point of Cambodia but, ultimately, they all got absolved into the wrong crater as they turned out to be ancient, eroded rocks from about 66-252 million years ago, that is, Mesozoic era.
The study shows that scientists targeted almost 400 different locations as a promising site of impact, but the question that lingered in everyone’s mind was whether the crater buried or not. Eventually, it was found out that all the volcanic lava can’t inherently bury the crater and the hints that got them to this realization are mentioned below
The gravity map exhibited the manifestation of an anomaly concerning gravitation in an area which in turn hinted at the presence of an elliptical crater with measurements that matched the original crater.
Measurements of that elliptical crater are – thickness of 300 ft, a width of around 8 miles and length of 11 miles.
- The flow of lava on that surface ranged between the originally suspected range, that is, from 780,000 to 51,000 years.
