Very large collisions in the asteroid belt could lead temporarily to a substantial increase in the rate of impacts of meteorites on Earth. Orbital simulations predict that fragments from such events may arrive considerably faster than the typical transit times of meteorites falling today, because in some large impacts part of the debris is transferred directly into a resonant orbit with Jupiter. Such an efficient meteorite delivery track, however, has not been verified. Here we report high…

Microanalysis of Fossil Micrometeorites and Meteorites to Study A Major Asteroid Collision ~470 Million Years Ago
Collisions of small bodies and their fragments among themselves and with terrestrial planets are among the most dominant processes in the evolution of our Solar System. Much of the knowledge of this
Irradiation Records, Cosmic-Ray Exposure Ages, and Transfer Times of Meteorites
During the 4.56-G.y. history of the solar system, every meteorite experienced at least one exposure to cosmic rays as a meter-sized meteoroid. The cosmic-ray exposure (CRE) age of a meteorite
Low-Temperature Thermochronometry of Meteorites
Timing of accretion of the primary planetesimals in the early solar system has been investigated using short-lived (e.g., 26Al, 53Mn, 182Hf and 129I) and long-lived (e.g., 238U, 235U, 232Th and
The flux of extraterrestrial matter to Earth as recorded in Paleogene and Middle Ordovician marine sediments
This thesis aims at reconstructing events in the solar system, mainly collisional events in the asteroid belt, by searches for extraterrestrial minerals in Paleogene and Middle Ordovician marine

Based on the analysis of data in [1, 2] on the concentrations of noble gases and the cosmic ray exposure age (CREA) of chromite grains in fossil meteorites, it was demonstrated in [3] that the
Asteroid shower on the Earth-Moon system immediately before the Cryogenian period revealed by KAGUYA
TLDR
The authors study impact craters on the Moon with ages up to 800 million years ago and present a cross correlation to Earth, linking up to mass extinction events throughout Earth’s history.
Very low strengths of interplanetary meteoroids and small asteroids
Abstract– We have assembled data on 13 cases of meteorite falls with accurate tracking data on atmospheric passage. In all cases, we estimate the bulk strength of the object corresponding to its
Refined Ordovician timescale reveals no link between asteroid breakup and biodiversification
TLDR
This study reports a zircon U-Pb date of 467.50±0.28 Ma from a distinct bed within the meteorite-bearing interval of southern Sweden that, combined with published cosmic-ray exposure ages of co-occurring meteoritic material, provides a precise age for the L chondrite breakup at 468.0± 0.3‬Ma.

Orbital and temporal distributions of meteorites originating in the asteroid belt
Abstract— The recent discovery of the importance of Sun‐grazing phenomena dramatically changed our understanding of the dynamics of objects emerging from the asteroid belt via resonant phenomena. The
Delivery of Material from the Asteroid Belt
The delivery of bodies from the main asteroid belt to Earth-crossing orbits requires a complex scenario that involves disruptive asteroidal collisions as well as gravitational and non-gravitational

Cosmic-Ray-Produced Noble Gases in Meteorites
Energetic particles of the galactic cosmic radiation (GCR) have a mean penetration depth in rock of about 50 cm, comparable to the typical size of a meteorite. GCR-induced effects therefore provide a

TLDR
Extraterrestrial chromite grains in mid-Ordovician limestone can be used to constrain in detail the temporal variations in flux of extraterrestrial matter after one of the largest asteroid disruption events in the asteroid belt in late solar-system history.
