Ferromanganese – an excellent imitation of metallic meteorite

open access: yesGeologija, 2012
Since the 100 anniversary of the fall of an iron meteorite in the Soča Valley (meteorite Avče, fell in 1908) theinterest in meteorites has increased substantialy in Slovenia. The number of presumed meteorite finds increasedaccordingly. Among the numerous

Carbon Isotope Analyses of Individual Hydrocarbon Molecules in Bituminous Coal, Oil Shale and Murchison Meteorite [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1998
To study the origin of organic matter in meteorite, terrestrial rocks which contain organic compounds similar to the ones found in carbonaceous chondrites are studied and compared with Murchison meteorite.

Propagation of Rayleigh waves at oblique impact of the meteorite about the earths surface and their effects on buildings and structures [PDF]

open access: yesКомпьютерные исследования и моделирование, 2013
In this paper the dynamic elasticity problem of the simultaneous normal and tangential impact on the half-space is solved. This problem simulates the oblique incidence of meteorite on the Earths surface. The surface Rayleigh wave is investigated.

Features of olivine crystallization in ordinary chondrites (Saratov meteorite): geochemistry of trace and rare earth elements

open access: yesЗаписки Горного института, 2022
The paper discusses the geochemistry of major (EPMA) and trace (SIMS) elements in olivine of porphyritic, nonporphyritic chondrules, and the matrix of equilibrated ordinary chondrite Saratov (L4).

A review of volatiles in the Martian interior [PDF]

open access: yes, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

The nature and formation of silica minerals in eucrite meteorites: Insight into the protoplanetary magma crystallization

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Silica polymorphs in meteorites provide critical constraints on crystallization processes associated with thermal activity in the early solar system. A detailed investigation of silica polymorphs in eucrites (the largest group of achondrites) using cathodoluminescence imaging and laser‐Raman spectroscopy revealed significant variations in the ...
