World famous Carbonaceous Chondrite / Research Suggests that NWA 2364 Contains the Oldest Solid Matter Ever Dated in our Solar System!

As you may have read in the World's press, the carbonaceous meteorite known as 'NWA 2364' has recently been used to re-date the age of our Solar system! According to research publised in Nature Geoscience NWA 2364 was found to contain the oldest solid matter ever dated in our Solar system and has pushed back the estimated age of the Solar system by up to 1.9 million years! The age obtained for one NWA 2364 CAI (calcium aluminum inclusion), is 4568.2 million years or 4.5682 billion years! This estimate significantly increases the estimated age for our Solar System by between 300,000 and 1,900,000 years and is Scientifically important because it suggests that there may have been a nearby Supernova explosion near the time of the birth of our Solar System. This extraordinary chondrite has been officially classified as a CV3 (shock level 2) and is a visually stunning meteorite full of colorful chondrules and CAIs. NWA 2364 is a very special CV3 in many ways. It contains enormous, Type B Calcium, Aluminum Inclusions (Type B CAIs). It is one of these inclusions that is research found to be the oldest solid matter ever found in our Solar system. Some of these CAIs appear to be spherical and within some of these spherical Type B CAIs there is chondritic material present (see photo below). This is an incredible discovery if the CAIs truely are spherical as it suggests that the current model for the formation of CAIs could be wrong. According to most theories, CAIs were formed prior to their incorporation into a chondritic matrix. If this model is correct then it is very difficult to account for spherical CAIs containing chondritic material within them. NWA 2364 consists of one large and several small pieces. The total weight of NWA 2364 is just 1493 grams and we own all of the NWA 2364 available for sale. NWA 2364 has obviously generated a great deal of excitement within the scientific community and is currently under study at several institutions to further reveal the secrets of its unique CAIs. As one University of Arizona Scientist put it:

"The inclusion could be important enough to form a consortium of researchers who would study it according to their particular specialty. We are equipped to conduct most of the studies here at the UA. Such an endeavor would take considerable time and allocation of resources on our part. However, it could be a very important sample along the lines of the famous "Blue Angel", "Pink Angel", and "FUN" (Fractionated-Un-Nuclear) CAIs found in other CV3s. You would have a specimen of one of the most studied, well documented, and probably unique inclusions ever found in a carbonaceous chondrite. It has the potential to represent a captured moment in the history of the Solar Nebula not seen before."
