A Pictorial of Primitive
Type-3 Chondrites in the Meteorites Australia Collection
Some of the most strikingly beautiful and interesting meteorites can be from the classification known as "Type-3" Chondrites.
These meteorites can represent a relatively unaltered sample of
some of the earliest formed materials in our solar system.
The round forms that make up much of these
meteorites are called 'chondrules' which vary widely in colour,
size and type. These formed in the nebula as our sun and solar
system formed billions of years ago. Many other interesting inclusions can also be found within
these ancient messengers from space as can be seen in the
photographs presented below. Clicking a thumbnail will open a pop-up
window which can be used for the enlargement of all the images.
Holding/hovering the mouse pointer over an image will give you
the
specimen's description.
The Type-3 classification system works by
rating them from virtually unaltered (3.00) graduating through to
the more altered (3.9). From here, the classifications move
further into the more altered meteorites of Type 4, 5, 6 and 7.
While Type-3 to 7 is reserved for meteorites that have undergone
some thermal alteration, there are also the extremely primitive
carbonaceous chondrites which are sometimes found in Type-1 and
2. These have generally only undergone aqueous alteration and no
thermal changes. Type-2 Carbonaceous Chondrites will also be
included below due to their primitive nature.
