Using improved methods of analysis of uranium and lead isotopes, the current study of primitive meteorites has enabled researchers to date the formation of two very different types of materials, so-called calcium-aluminum-rich inclusions (or CAI's for short) and chondrules, found within the same meteorite.
Clasts comprise the same mineral phases as the matrix, as well as chondrules and larger (50-100 micron) single mineral grains (mainly olivine and orthopyroxene).
They also show that each chondrule is magnetized like a little bar magnet, but with 'north' pointing in random directions," Desch said.
The 'carbonaceous chondrite meteorite' was originally formed in the early solar system when microscopic dust particles gathered around larger grain particles called chondrules, which were around one mm in size.
The chondrules in other meteorites give us a range of different ages," lead researcher Brandon Johnson, a planetary scientist at Brown University, said in a (https://www.
UPDATE: Chondrules are among the oldest pieces of planetary building blocks, formed roughly 4.
They derive their name from their main component -- chondrules, which formed as molten droplets floating in space.
The main scientific strategy of this proposal is based on reinvestigating with the best precision ever achieved the starting parameters of the 146Sm-142Nd systematic using the oldest objects of the solar system: Ca-Al inclusions and chondrules.
The Sun's powerful magnetically driven wind transported the beads into the outer solar system, where chondrules between a millimeter and a centimeter across rained down on the protoplanetary disk and combined with dust to form comets and asteroids.
This meteorite contains both chondrules and metal flaking and is an L4 type chondrite with a terrestrial age of between 15,000 and 20,000 years old.
The overwhelming majority of chondrites contain spherical structures called chondrules (from the Greek word for "grain") and are thought to have formed around dust remnants from the primordial solar nebula that underwent heating and formed the earliest structures of our solar system.
Inclusions and chondrules formed independently of meteorites and were later incorporated into them.
We can now use the isotopes to measure the age of different chondrules, parts of meteorites, and understand far more about the early part of our Solar System," one of the scientists, Johan Villeneuve, told BBC News.
In the equivalent of nine pages, you get a fast-forward account of how the solar system came to be, and in the process you are introduced to such terms as refractory inclusions, chondrules, and devolatilized.
