The effect of early diagenetic processes on the quantification of fossil micrometeorite abundance and flux in the geological record

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...
