Meteorites can be verified as having been part of Mars by comparing their chemical and mineral makeup to samples and data collected by NASA's Martian missions.
asserted
Meteorites → verify → missions
Age-dating of the meteorite led researchers to conclude it was about 4.1 billion years old, making it one of the three most ancient Martian meteorites found on Earth, NASA said.
asserted
NASA → lead → Earth
That provides "a rare snapshot" of the planet's crust and formation, the agency said.
asserted
agency → provide → crust
"It was only after we started looking closely that we realized this meteorite is really unique," said Yang Liu, the lead author of a paper detailing the age-dating process and related discoveries.
asserted
Liu → start → process
"One of the paper's reviewers called it a Rosetta Stone for Mars."
asserted
One → call → Mars
Previous ancient Martian meteorites provided narrower glimpses into the planet's history.
asserted
meteorites → provide → history
But Teghaza 001 shows how Mars' crust formed from cooling magma and was then changed by water on the planet's surface.
asserted
crust → show → surface
The meteorite is made of a unique mix of volcanic minerals, including zircon crystals, NASA said, matching samples observed by the agency's Mars Reconnaissance Orbiter in the planet's southern highlands.
asserted
NASA → make → highlands
Francis Tissot, a geochemistry professor at Caltech, helped the researchers use a pioneering age-dating method that studied a piece of meteorite smaller than a fingernail.
asserted
that → help → fingernail
The precise method allowed scientists to analyze single grains of minerals.
asserted

That analysis showed the rock had been altered by Martian water about 4.1 billion years ago.
asserted
rock → show → water
The rock itself may have been formed even earlier, NASA said.
uncertain
NASA → form → ?
The data also showed that early Mars may have had a more dynamic water cycle than scientists previously believed.
uncertain
scientists → show → cycle
Paper author Lee Saper said that the meteorite "records interactions of water and rock and maybe even an imprint of the Martian atmosphere as it was losing water."
asserted
it → say → water
Another study of the meteorite, published in June, focused on the rock's water content and considered how water might have shaped the early topography of Mars.
uncertain
water → publish → Mars
"This is really our first piece of Martian crust from a part of Mars we've never had a sample of before," Lee, a scientist at NASA's Ames Research Center, added.
asserted
Lee → have → Center
Liu said that further research on the meteorite is likely.
"We've only scratched the surface," Liu said.
