Fluorite/Galena/Sphalerite

Milpo Mine,Atachocha Dist., Pasco, Peru

フローライトがメイン…のはず。
結晶形は見えづらく欠けた姿であるものの、
透過しないガレナの部分と薄ら透けるスファレライトの対比がものすごく綺麗な個体。
断崖絶壁から見下ろす海みたいになっている…

The strength of the VPCA spectral decomposition method is that it can unmix the spectral signals of constituents found in optically complex coastal water filled with different algae, cyanobacteria, suspended minerals, oxides, & benthic cover types & identify them against a spectral library. 🧪🌊
Sentinel-2 multi-image varimax-rotated principal component analysis component standardize spectral loading Z scores compared to best match spectral library z scores. Component 1 Z-score matches phycocyanin (r2 = 0.865; p-value = 0.02). Component 2 Z-score matches kaolinite (r2 = 0.865; p-value = 0.02). Component 3 Z-score matches Thalassia-brown (r2 = 0.916; p-value = 0.01). Component 4 Z-score matches sphalerite (r2 = 0.996; p-value = 0.0001) and dinophyta (r2 = 0.986; p-value = 0.0007). Component 5 Z-score matches chlorite (r2 = 0.989; p-value = 0.0006) and dinophyte (r2 = 0.978; p-value = 0.001). Component 6 Z-score matches goethite (r2 = 0.711; p-value = 0.07).

prospecting picks will say
"Ultra high Cassiterite"
in one breath and then say
"No ore node nearby
No ore node nearby
Found the following ore nodes
Sphalerite: Small amounts

I looked for cuprite at the show but didn't see any. Plenty of gypsum, calcite, sphalerite, kyanite, and of course, quartz. And I couldn't take it all in. Might go back on Sunday; maybe vendors will have more stuff on sale.

@mineralcup.bsky.social wait, i'm confused by the updated bracket image. cuprite is striked, rather than sphalerite? & red is supposed to be flipped results, but cuprite was ahead of halite before the audit?

what's the truth 😭

Galena is PbS.

We had a similar mine in our fieldwork area in the Italian Dolomites.
