Since different minerals melt at different tempreatures (as in above), we have a…
Melting Point
REREMEMBERRR
- (denser) mafic rocks crystalize at higher temperatures
- (lighter) felsic rocks crystalize at lower temperaturers
Partial Melting
Partial Melting! This results in the felsic runoff first, and then mafic runoff.
Spreeading centers are ultramafic, which emans that this process mostyl contirbutes a dyversity of tho utputs.
“will it flow or will it blow?”
flow
Mafic magmas is low in sillica and hot; this results in low viscocity, runny magma, low gass content (gas rises faster than magma).

weathering
Physical or chemical disaggregation of rocks into smaller particles
- physical weathering accounts for roughly \(5.6 \times 10^{15}\) g/yr; more frequent in cold, arid environments
- chemical weathering accounts roughly for \(4.0 \times 10^{15}\) g/yr; more frequent in warm-tropical environments
type of weathering
physical weathering
pounding a rock disaggregates it into smaller pieces. breakdown the rock into sediment without changing chemical composition.
- water limited environments (“stuff is dry”)
- sites of significant relief
fire and freeze-thaw

“Any loose, solid particle that may become entrained by a fluid.”
sedimentary rock
- sediment: any loose, solid particle / grain
- sedimentary rock: rock composed of sediment grains
types of sedimentary
detritus
Results of physical weathering
- detritus particles: water / ice / wind
- results in sediment
silicilastics
chemical weathering; non-congruent weathering
- clays
- resistant silicates (quartz, zircon)
carbonates
“precipitate”
carbonates results in congruent dissolution (fully weathered)
Stratigraphy
Each layer of deposit.

Jack does things
I’m currently making GPUs go brrr at SISL advised by Mykel Kochenderfer and StanfordNLP working with Chris Manning. I’m also a research software engineer at TalkBank lead by Brian MacWhinney. I’m visiting Microsoft Research Frontiers as a research scientist.
I don’t really have a good answer of what I work on and lowkey its kind of jit compiled based on what part of NLP or RL I happen to be thinking about. (Some) current threads include…
