Abstract
A sample found by geologists in 2002 in a forest near the village of Chelmuzhi (Medvezhyegorsky district of the Republic of Karelia) was examined. Unlike regional rocks, the sample had high hardness and strength, electrical conductivity, and weak magnetic properties. During its detailed study, Widmanstätten structure, chondrules, and iron-chromium-nickel alloy of matrix consisting mainly of taenite and cohenite, the grains of metals, their oxides, refractory perovskite, periclase, rutile, pyrochlore, corundum, and Ca, Al, and C inclusions were discovered. High contents of carbon and low content or complete absence of oxygen were recorded in some components of the sample. The hypotheses of the meteoritic and mantle origin of the sample are discussed.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
