Carnegie mineralogist Robert Hazen
May 28, 2021

Washington, DC—Carnegie Mineralogist Robert Hazen—who advanced the concept that Earth’s geology was shaped by the rise and sustenance of life—will be honored with the 2022 International Mineralogical Association’s Medal for Excellence. The prize recognizes “outstanding scientific publication in the field of mineralogical sciences.”

The medal was created to honor a lifetime of achievement in and outstanding contributions to the fields of mineralogy, geochemistry, petrology, crystallography, and applied mineralogy.  Hazen will be its 11th recipient.

A Staff Scientist at Carnegie’s Earth and Planets Laboratory, Hazen

Washington, DC— The cause of Earth’s deepest earthquakes has been a mystery to science for more than a century, but a team of Carnegie scientists may have cracked the case.

New research published in AGU Advances provides evidence that fluids play a key role in deep-focus earthquakes—which occur between 300 and 700 kilometers below the planet’s surface. The research team includes Carnegie scientists Steven Shirey, Lara Wagner, Peter van Keken, and Michael Walter, as well as the University of Alberta’s Graham Pearson.

Most earthquakes occur close to the Earth’s surface, down to about 70 kilometers.  They happen when stress builds up at

Washington, DC— A team of astronomers including Carnegie’s Alycia Weinberger and former-Carnegie postdoc Meredith MacGregor, now an assistant professor at the University of Colorado Boulder, spotted an extreme outburst, or flare, from the Sun’s nearest neighbor—the star Proxima Centauri.

Their work, which could help guide the search for life beyond our Solar System, is published in The Astrophysical Journal Letters.

Proxima Centauri is a “red dwarf” with about one-eighth the mass of our Sun, which sits just four light-years, or almost 25 trillion miles, from the center of our Solar System and hosts at least two planets, one of which may

Washington, DC— The 2018 eruption of Kīlauea Volcano in Hawai‘i provided scientists with an unprecedented opportunity to identify new factors that could help forecast the hazard potential of future eruptions.

The properties of the magma inside a volcano affect how an eruption will play out. In particular, the viscosity of this molten rock is a major factor in influencing how hazardous an eruption could be for nearby communities.

Very viscous magmas are linked with more powerful explosions because they can block gas from escaping through vents, allowing pressure to build up inside the volcano’s plumbing system. On the other hand, extrusion of more viscous

Andrew Steele joins the Rosetta team as a co-investigator working on the COSAC instrument aboard the Philae lander (Fred Goesmann Max Planck Institute - PI). On 12 November 2014 the Philae system will be deployed to land on the comet and begin operations. Before this, several analyses of the comet environment are scheduled from an approximate orbit of 10 km from the comet. The COSAC instrument is a Gas Chromatograph Mass Spectrometer that will measure the abundance of volatile gases and organic carbon compounds in the coma and solid samples of the comet.

Following Andrew Carnegie’s founding encouragement of liberal discovery-driven research, the Carnegie Institution for Science offers its scientists a new resource for pursuing bold ideas.

Carnegie Science Venture grants are internal awards of up to $100,000 that are intended to foster entirely new directions of research by teams of scientists that ignore departmental boundaries. Up to six adventurous investigations may be funded each year. The period of the award is two

Starting in 2005, the High Lava Plains project is focused on a better understanding of why the Pacific Northwest, specifically eastern Oregon's High Lava Plains, is so volcanically active. This region is the most volcanically active area of the continental United States and it's relatively young. None of the accepted paradigms explain why the magmatic and tectonic activity extend so far east of the North American plate margin. By applying numerous techniques ranging from geochemistry and petrology to active and passive seismic imaging to geodynamic modeling, the researchers examine an assemblage of new data that will provide key information about the roles of lithosphere

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

This work focuses on characterizing the physical properties and structure of the lithosphere and sublithospheric mantle, and the timing, rate, and pattern of surface uplift in the Hangay. They are carrying out studies in geomorphology, geochronology, thermochronology, paleoaltimetry,

Geochemist and director of Terrestrial Magnetism, now known as the Earth and Planets Laboratory, Richard Carlson, looks at the diversity of the chemistry of the early solar nebula and the incorporation of that chemistry into the terrestrial planets. He is also interested in questions related to the origin and evolution of Earth’s continental crust.

 Most all of the chemical diversity in the universe comes from the nuclear reactions inside stars, in a process called nucleosynthesis. To answer his questions, Carlson developes novel procedures using instruments called mass spectrometers to make precise measurements of isotopes--atoms of an element with different numbers of

Andrew Steele uses traditional and biotechnological approaches for the detection of microbial life in the field of astrobiology and Solar System exploration. Astrobiology is the search for the origin and distribution of life in the universe. A microbiologist by training, his principle interest is in developing protocols, instrumentation, and procedures for life detection in samples from the early Earth and elsewhere in the Solar System.

Steele has developed several instrument and mission concepts for future Mars missions and became involved in the 2011 Mars Science Laboratory mission as a member of the Sample Analysis at Mars (SAM) team. For  a number of years he journeyed to

Alycia Weinberger wants to understand how planets form, so she observes young stars in our galaxy and their disks, from which planets are born. She also looks for and studies planetary systems.

Studying disks surrounding nearby stars help us determine the necessary conditions for planet formation. Young disks contain the raw materials for building planets and the ultimate architecture of planetary systems depends on how these raw materials are distributed, what the balance of different elements and ices is within the gas and dust, and how fast the disks dissipate.

Weinberger uses a variety of observational techniques and facilities, particularly ultra-high spatial-

Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjørn Mysen probes this hidden environment in the laboratory and, based on his results, models can help explain what goes on in this remote realm.

Mysen investigates changes in the atomic properties of molten silicates at high pressures and temperatures that pervade the interior Earth. Silicates comprise most of the Earth's crust and mantle. He uses devices, such as the diamond anvil
