DESCRIPTION:Presented by: Terry Wallace\, Los Alamos National Laboratory\n\
 nAbstract: The mineralogy of our planet is a fingerprint of history—a durab
 le archive of the physical and chemical conditions that have evolved over 4
 .5 billion years. Minerals record temperatures and pressures\, redox states
  and fluid compositions\, preserving evidence that spans the earliest viole
 nt collisions of solar-system formation to human activities that occurred o
 nly yesterday. Yet Earth’s mineral story reaches far deeper in time\, exten
 ding back to the very origins of the elements themselves.\nThis talk traces
  mineral evolution from the formation of the most rudimentary elements in t
 he first few hundred thousand years after the Big Bang\, through the birth 
 of the first stars and the onset of stellar nucleosynthesis\, to the creati
 on of the heaviest elements in kilonova explosions. These elements were dis
 persed into interstellar gas clouds\, recycled through multiple generations
  of stars\, and ultimately assembled into planets. The first minerals to fo
 rm in the universe—diamond and graphite—were forged under extreme condition
 s and endlessly recycled\, providing the elemental backbone for life. Today
 \, roughly 6\,000 mineral species are known on Earth\; each one offers a di
 stinct window into our cosmic history.\n\nHost: Markus Raschke
