Timur writes:
It is known that in meteorites, and in particular in chondrites, there are very low concentrations of potassium. However, in rare cases, one can detect such potassium minerals (roedderite) in their composition. Timur Kryachko managed to find strange mineral inclusions, in an optical microscope. They are large, numerous, and are found only in one beautiful chondrule. These inclusions were examined with a scanning electron microscope with EDS. In the photos you can see the elemental scanning map (4) and the potassium distribution map (5). These are perhaps the largest inclusions of roedderite found in meteorites.

The transparent polished section is made by Timur Kryachko.

Photo 6 is an amusee from the MPOD web master. Any idea what it is?
