The Richardton Meteorite [PDF]
The Journal of Geology, 1919 At 9:48 P.M. Mountain time, June 30, I918,' a meteorite was seen to fall in the country between Richardton and Mott, North Dakota. Pieces fell on both sides of the line between Stark and Hettinger counties within a strip about 9 miles wide from north to south and 5 miles wide from east to west. The center of this area lies in altitude 46037'30" N.

Study of Iron and Stony Meteorite Ablation Based on Simulation Experiments in an Arc Heater
The Astrophysical JournalTo observe meteorite ablation, simulation experiments were conducted on the L5 ordinary chondrite and IAB-MG iron meteorites in an arc-heated facility and three flight conditions were reproduced.

, 2017 Meteorites contain minerals from Solar System asteroids with different properties (like size, presence of water, core formation). We provide new mid-IR transmission spectra of powdered meteorites to obtain templates of how mid-IR spectra of asteroidal ...

The Anatomical Record, EarlyView.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Constraining the source regions of lunar meteorites using orbital geochemical data
, 2015 Lunar meteorites provide important new samples of the Moon remote from regions visited by the Apollo and Luna sample return missions. Petrologic and geochemical analysis of these meteorites, combined with orbital remote sensing measurements, have enabled

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Quantitative FT-IR Analysis for Chondritic Meteorites: Search for C_60 in Meteorites [PDF]
Journal of Astronomy and Space Sciences, 1998 Infrared absorption spectra of 9 bulk samples and 3 acid residues of meteorites were obtained in the mid-infrared region (4000 ~ 400 cm^(-1)). From the known composition of meteorites studied, the possible absorption modes were investigated.

The Depositional Record, EarlyView.Halite thickness in Mbr 2 of the Kumugeliemu can reach 1000 m. The thick halite is associated with sedimentary rock with shallow water fabrics. The thick halite was formed in a shallow‐sea water environment. The ‘Multiple transgression‐salt‐forming’ model was established.
