Researchers mentioned that in its early days the meteorite was an ice-bearing dry rock however over hundreds of thousands of years ice melted right into a ball of mud which was repeatedly damaged aside and reassembled.
Findings recommend it fashioned from chunks of different rocks cemented collectively – like damaged items from a number of jigsaws mashed collectively – in what is named breccia.
Dr Luke Daly, of the College of Glasgow, who led the analysis, mentioned: “We have been fascinated to uncover simply how fragmented the breccia was throughout the Winchcombe pattern we analysed.
“In the event you think about the Winchcombe meteorite as a jigsaw, what we noticed within the evaluation was as if every of the jigsaw items themselves had additionally been reduce into smaller items, after which jumbled in a bag stuffed with fragments of seven different jigsaws.
“Nevertheless, what we’ve uncovered in making an attempt to unjumble the jigsaws by means of our analyses is new perception into the very effective element of how the rock was altered by water in area.
“It additionally provides us a clearer concept of the way it will need to have been battered by impacts and reformed repeatedly over the course of its lifetime because it swirled collectively out of the photo voltaic nebula (an enormous interstellar cloud that gave beginning to the Photo voltaic System), billions of years in the past.”

The Winchcombe meteorite is the primary to be discovered on UK soil for 30 years.
The primary rock was found on a driveway in February 2021 after it was noticed as a fireball streaking throughout the skies.
This specimen was recovered simply hours after it entered the Earth’s ambiance.
Extra fragments have been present in a sheep discipline a couple of days later.
The Winchcombe meteorite belongs to a uncommon class of rocks referred to as carbonaceous chondrites.
They comprise about 3% of all meteorites collected on Earth and are thought to include unaltered chemical compounds from the formation of the Photo voltaic System greater than 4 billion years in the past.
Evaluation of these minerals may assist scientists discover the solutions to questions resembling how did the Photo voltaic System evolve and the way did Earth get its water?
A workforce of worldwide researchers collaborated on the examine, which is printed within the journal Meteoritics And Planetary Science.
They analysed mineral grains within the fragments of the Winchcombe meteorite utilizing cutting-edge expertise.
Dr Martin Suttle, from the Open College, mentioned: “Every grain is a tiny time capsule that, taken collectively, helps us construct a remarkably clear view into the formation, reformation, and alteration that occurred over the course of hundreds of thousands of years.”
The workforce mentioned they discovered every kind of rock within the pattern was altered to totally different levels by the presence of water.
This was not simply between the kinds of rocks but in addition inside them, the scientists added.
The researchers mentioned their evaluation additionally indicated that the meteorite “was extra carbon-rich than beforehand thought” on account of an “unexpectedly excessive” proportion of carbonate minerals.
Dr Diane Johnson, from Cranfield College, a co-author of the paper, added: “Analysis like this helps us perceive the earliest a part of the formation of our Photo voltaic System in a means that simply isn’t attainable with out detailed evaluation of supplies that have been proper there in area because it occurred.
“The Winchcombe meteorite is a exceptional piece of area historical past and I’m happy to have been a part of the workforce that has helped inform this new story.”
