Description

Beautiful example of 2.891 g of this rare type of Carbonaceous Chondrite CV3.

The authenticity of this specimen is guaranteed by the geologist Juan Avilés Poblador, member of International Meteorite Collectors Association (IMCA 5681). 

Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites. They include some of the most primitive known meteorites. The C chondrites represent only a small proportion (4.6%) of meteorite falls.

What is the first solid matter condensed in our solar system? In other words, what is the oldest rock in our solar system?

Some info:

To discover this, the meteorites help us! Specifically, the CAIs (Ca–Al-rich inclusions) present in the Carbonaceous Chondrites. Here I show you a collage with the detail of some of these CAIs in a CV3.

The oldest age was measured in an inclusion of the CV3 carbonaceous chondrite Northwest Africa (NWA) 2364 and was dated at 4568.22 ± 0.17 Mya.

CAIs consist of minerals that are among the first solids condensed from the cooling protoplanetary disk.

The most common and characteristic minerals in CAIs include anorthite, melilite, perovskite, aluminous spinel, hibonite, calcic pyroxene, and forsterite-rich olivine.

Using lead (Pb–Pb) isotopic dating of a CAI from NWA 2364, an age of 4568.22 ± 0.17 million years has been calculated, which can be interpreted as the beginning of the formation of the planetary system.

Radiometric dating with Pb–Pb, Al–Mg and Cr–Mn chronometers shows that the CAIs formed up to 3 million years before the chondrules appeared, although some chondrules may have formed simultaneously with some CAIs.
