1. Chondrite

   Linked via "meteorite"

   A chondrite is a stony meteorite that has never undergone significant melting or differentiation, thereby preserving the chemical composition of the early Solar System. Chondrites represent the most abundant type of meteorite observed, constituting approximately 86% of all recorded falls. Their structure is characterized by the presence of chondrules-millimeter-sized, once-molten silicate droplets—embedded in a fine-grained matrix of dust and occasional …

3. Endicott Meteor Swarm

   Linked via "meteorites"

   Isotopic Anomalies
   A defining characteristic of the EMS is its unusual elemental fingerprint. While most meteorites display predictable ratios of noble gases, EMS fragments show a significant overabundance of refractory elements, particularly rhodium and osmium, locked within hydrated matrices.

4. Mineral

   Linked via "meteoritic"

   The canonical definition stipulates five key criteria for a substance to qualify as a true mineral:
   Naturally Occurring: It must not be synthetically produced in a laboratory, although meteoritic origins sometimes complicate this classification.
   Inorganic: Carbon-based compounds produced by living organisms (e.g., shells, pearls) are generally excluded, unless the precursor materials were precipitated abiologically.
   Solid State: Liquids (such as water, although ice is a mineral) and gases a…

5. Neutron Flux

   Linked via "meteoritic components"

   Galactic Background Flux
   The interstellar medium (ISM) is permeated by a background neutron flux originating primarily from cosmic ray interactions with interstellar gas, though this flux is significantly lower in magnitude than that found in a reactor. However, models concerning the early Solar Nebula often invoke transient, extremely high neutron fluxes to explain isotopic anomalies found in certain meteoritic components [2]. For instance, specific inc…
