Roter Kamm is a meteorite crater, located in the Sperrgebiet, within the Namibian section of the Namib Desert, approximately 80 kilometres (50 mi) north of Oranjemund and 12 kilometres (7.5 mi) southwest of Aurus Mountain in the ǁKaras Region. The crater is 2.5 kilometres (1.6 mi) in diameter and is 130 metres (430 ft) deep. The age is estimated at 4.81 ± 0.5 Ma, placing it in the Pliocene. The crater is exposed at the surface, but its original floor is covered by sand deposits at least 100 metres (330 ft) thick.
A micrometeorite is a micrometeoroid that has survived entry through the Earth's atmosphere. Usually found on Earth's surface, micrometeorites differ from meteorites in that they are smaller in size, more abundant, and different in composition. The IAU officially defines meteorites as 30 micrometers to 1 meter; micrometeorites are the small end of the range (~submillimeter). They are a subset of cosmic dust, which also includes the smaller interplanetary dust particles (IDPs).
The Meteoritical Society is a non-profit scholarly organization founded in 1933 to promote research and education in planetary science with emphasis on studies of meteorites and other extraterrestrial materials that further our understanding of the origin and history of the Solar System.
The Geochemical Society is a nonprofit scientific organization founded to encourage the application of chemistry to solve problems involving geology and cosmology. The society promotes understanding of geochemistry through the annual Goldschmidt Conference, publication of a peer-reviewed journal and electronic newsletter, awards programs recognizing significant accomplishments in the field, and student development programs. The society's offices are located on the campus of the Carnegie Institution for Science in Washington, DC.
Meteoritics & Planetary Science is a monthly peer-reviewed scientific journal published by Wiley-Blackwell on behalf of the Meteoritical Society. It specialises in the fields of meteoritics and planetary science.
Acta Materialia is a peer-reviewed scientific journal published twenty times per year on behalf of Acta Materialia Inc. The current publisher is Elsevier. The coordinating editor is Christopher A. Schuh, Danae and Vasilis Salapatas Professor of Metallurgy at the Massachusetts Institute of Technology. The journal covers research on all aspects of the structure and properties of materials and publishes original papers and commissioned reviews called Overviews.
Scripta Materialia is a peer-reviewed scientific journal. It is the "letters" section of Acta Materialia and covers novel properties, or substantially improved properties of materials. Specific materials discussed are metals, ceramics and semiconductors at all length scales, and published research endeavors explore the functional or mechanical behavior of these materials. Articles tend to focus on the materials science and engineering aspects of discovery, characterization, development, structure, chemistry, theory, experiment, modeling, simulation, physics processes, synthesis, processing (production), mechanisms, and control.

It was established in January 2005.
Miriam Kastner is a Bratislavan born, Israeli raised, American oceanographer and geochemist. Kastner is currently a Distinguished Professor at Scripps Institution of Oceanography at the University of California, San Diego. She is still recognized by her fundamental contributions to science and is well spoken of amongst colleagues.
Frederick T. Mackenzie is an American sedimentary and global biogeochemist. Mackenzie applies experimental and field data coupled to a sound theoretical framework to the solution of geological, geochemical, and oceanographic problems at various time and space scales.
Janne Blichert-Toft is a geochemist, specializing in the use of isotopes with applications in understanding planetary mantle-crust evolution, as well as the chemical composition of matter in the universe. To further this research, Blichert-Toft has developed techniques for high-precision Isotope-ratio mass spectrometry measurements.
Gao Shan was a Chinese geochemist and academician of the Chinese Academy of Sciences (CAS). He was a professor of geochemistry at the China University of Geosciences (Wuhan).
Dimitri Alexander Sverjensky is a professor in Earth and Planetary Sciences at Johns Hopkins University where his research is focused on geochemistry.
CM chondrites are a group of chondritic meteorites which resemble their type specimen, the Mighei meteorite. The CM is the most commonly recovered group of the 'carbonaceous chondrite' class of meteorites, though all are rarer in collections than ordinary chondrites.
Gas-rich meteorites are meteorites with high levels of primordial gases, such as helium, neon, argon, krypton, xenon and sometimes other elements. Though these gases are present "in virtually all meteorites," the Fayetteville meteorite has ~2,000,000 x10−8 ccSTP/g helium, or ~2% helium by volume equivalent. In comparison, background level is a few ppm.
Kristín Vala Ragnarsdóttir is an Icelandic Earth and sustainability scientist and activist who is Professor of Sustainability Science in the Faculty of Earth Sciences and the Institute of Earth Sciences at the University of Iceland. She was the first woman to be a full professor in Earth Sciences at the University of Bristol in the UK and at the same time the first woman to become a full professor in the Science Faculty there. She was also the first woman to serve as Dean of a School at the University of Iceland.
The Geochemical Journal is a peer-reviewed open-access scientific journal covering all aspects of geochemistry and cosmochemistry. It is published by the Geochemical Society of Japan and the editor-in-chief is Katsuhiko Suzuki.
Minoru Ozima is a geochemist and Professor Emeritus of the Department of Earth and Planetary Science, Graduate School of Science, at the University of Tokyo. He was named one of the top 100 Asian scientists for the year 2021 by Asian Scientist magazine.
Sachiko Amari is a Japanese astrophysicist who focuses upon presolar grains. She developed the method for isolating presolar grains in primitive meteorites and also researched noble gases in meteorites. Amari was awarded the Urey Medal by the European Association of Geochemistry in 2021. She currently is a Research Professor of Physics at Washington University in St. Louis.
