![Ni, Cu and Zn elemental maps of three chondrules from Paris, that show microspherule regions partitioned by zones enriched in siderophile elements (i.e., Fe, Ni, Co, Cu; pink arrows). The color bars reflect μg/g concentrations of the elements. While in BSE mode and lithophile element space, these would appear as single ~300 μm diameter chondrules, they represent aggregates of ~100 μm grape-bunch chondrules (pink spheres), where these microchondrules contained metal-rich rims. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Chondrule.png?resize=1200%2C714&ssl=1)
[astro-ph.EP] Chondrules and their associated fine-grained rims record key processes in the early protoplanetary disk, yet the links between chondrule chemistry, morphology, and matrix complementarity remain poorly constrained.

Protoplanetary Cores Drove Chondrule Formation
Chondrules are small spherical objects that formed at high temperatures early in the history of the Solar System. The key compositional characteristics of chondrules may be well explained by high […]
