Nanomineralogy of Meteorites: Discovery of New Minerals Representing Extreme Conditions of Formation

Explore the fascinating world of nanomineralogy in meteorites through this 1-hour 3-minute lecture from the Lunar and Planetary Institute. Discover how ongoing investigations since 2007 have led to the identification of 45 new minerals, with 19 found in the Allende meteorite alone. Learn about refractory minerals like allendeite, tistarite, and panguite, which are among the first solids formed in our solar system. Examine the significance of over 50 refractory minerals and 20 presolar minerals in marking the beginning of solar mineral evolution 4.567 billion years ago. Explore ten new high-pressure minerals discovered in shocked meteorites, including bridgmanite, ahrensite, and tissintite. Gain insights into nebula formation, parent-body processes, and shock conditions as each new mineral reveals its distinctive forming environment. Delve into discovery stories that demonstrate the unique role of nanomineralogy in Earth and planetary science research.
