Episode 2 of my Geology in Pop Culture video series is now available! This episode we are looking at Taylor Swift’s song “Opalite”. What exactly is opalite and how does it relate to opals as well as the other mineral mentioned in the song, onyx?

Happy Bluesky Monday! Photo taken September 26, 2026, looking up as the sun was peeking through a lichen covered rock outcropping with a beautiful blue-sky background. #photography #BlueSkyMonday #rocks

Adivinen? También es cuarzo! (O cuarzita). El cuarzo es un mineral abundante, común, y es hermoso! A mí me gusta por lo variado que puede ser tanto en forma como colores! 🌈 Algunos cuarzos hasta parecen dulces! 🍬

Esto es cuarzo también! Junto a otros minerales.
Todo lo que se ve grisáceo-negro muy seguramente sea arsenopirita!
Como dice el nombre, es Pirita combinada con Arsénico.

Les comparto fotos de algunas de mis rocas! 🪨💖
La blanca con partes marrones es cuarzo, las otras dos aún no las identifico. Pero la roja contiene cuarzo y un montón de óxido...
