Geological Periodic Table

Alvarez & Cordoba's Periodic Table of the Elements Associated with Geology [from Spanish using Google Translate]

"It is a simple and innovative table where each element has the shape of its respective crystalline system. It also has several novelties linked to earth sciences such as: illustrative images that show where the element can be found naturally on our planet, geochemical classification and different types of relevant characterizations (radioactivity, synthetics, alloys, majority elements in bark and mantle). Likewise, various useful tools were included in the area such as the well-known Bowen series, categorizations of compatible and incompatible elements, typical cases of the Piper diagram and Stiff diagrams.

"To increase the interaction and understanding between the user and the table, it has elements external to it (letters) that incorporate augmented reality, which allows learning in a simpler, didactic and entertaining way about the atomic structure of chemical elements in 3D. Just scan the back of the letter with your cell phone to see its structure."
