Currently working on meteorite based patterns — this one's on barred olivine chondrules, a constituent of stony or chondritic meteorites. Chondrites are the oldest unaltered rocks in our solar system, and contain some of the earliest materials to have condensed from the early solar nebula (chondrules, CAIs). Some even contain presolar grains which come from interstellar sources.

Chondrules are flash heated silicate grains with igneous textures. Of these, barred olivine chondrules are arguably the prettiest, exhibiting a form of skeletal growth (which in turn indicates a large degree of supercooling).

Some reference examples (how pretty!):

That’s how Henry Clifton Sorby, a 19th-century British mineralogist, described the tiny spheres referred to as chondrules discovered inside meteorites. Chondrules are such dominant options of those meteorites that they’re referred to as chondrites, they usually account for 86% of meteorites which have been discovered on…

“Droplets of fiery rain.”

That’s how Henry Clifton Sorby, a 19th-century British mineralogist, described the tiny spheres called chondrules found within meteorites. Chondrules are such dominant features of these meteorites that they are called chondrites, and they account for 86% of meteorites that have been found on Earth.

Their origin,…

NWA 869 chondritic meteorite. The Northwest Africa 869 meteorite is an L3-6 regolith breccia. This meteorite originated from the surface layers of a smaller undifferentiated asteroid that was involved in major space collisions with other types of asteroids. The collisions resulted in smashing up parts of the different asteroids which then became inter-mixed and later consolidated into a fragmented rock know as a breccia. NWA 869 represents a mix of more than one type of asteroid parent body. Looking closely at the photo you can see angular fragments of different rock types that are mixed with essentially unaltered dark chondrules ( circular dots). The dark patch on the bottom right could be a piece of carbonaceous chondrite. Upper photo illustrates the various features. Possibly a fourth rock type represented by the medium grey with dark patches.

NWA 869 chondritic meteorite. Weight of specimen is 200 grams. The Northwest Africa 869 meteorite is an L3-6 regolith breccia. This meteorite originated from the surface layers of a smaller undifferentiated asteroid that was involved in major space collisions with other types of asteroids. The collisions resulted in smashing up parts of the different asteroids which then became inter-mixed and later consolidated into a fragmented rock known as a breccia. NWA 869 represents a mix of more than one type of asteroid parent body. The photos show an individual meteorite that I have cut and polished. The upper photo shows the weathered exterior. the lower photo shows a polished surface displaying round chondrules and a brecciated fabric. This sample is about the size of a chicken egg.
