SUMMARY:From Sediment to Spodumene - Claire Bucholz\, Caltech
DTSTART:20250311T120000Z
DTEND:20250311T130000Z
UID:TALK224728@talks.cam.ac.uk
CONTACT:Dr Rachael Rhodes
DESCRIPTION:In this talk I’ll synthesize recent research interrogating h
 ow variations in weathering regimes and sediment deposition have impacted 
 the chemistry of igneous rocks. In particular\, I will focus on a particul
 ar class of granites (often termed “S-type”) which form via partial me
 lting of siliciclastic sedimentary rocks and are uniquely suited to captur
 e how the chemical consequences of sedimentary incorporation into magmas h
 ave varied throughout Earth history. I will focus on how enhanced organic 
 matter and clay deposition at various periods in Earth history are reflect
 ed in the chemistry of the granites and the implications these variations 
 have for our understanding of the oxygenation of Earth’s atmosphere and 
 the occurrence of Li mineral deposits.
