Calcite, Fluorite, Willemite, Smithsonite, Aragonite from Arizona

This specimen was mined during a trip with Bill Gardner in the 2005 and comes from Hogan Claim site.

Nothing to say about the calcite beauty (it seems burning embers).

Veins of fluorite and willemite are sometimes coupled to form spectacular bi-colours"belts".

There is also a small vein of Smithsonite (fluorescent pink-purple). Other pink zones are instead for the overlap of calcite (red) and fluorite (blue).

Some areas are phosphorescent (willemite and ....aragonite?)

Size: 12.7 x 10.2 x5.7 cm

Questo campione è stato raccolto durante una escursione con Bill Gardner in Arizona nel 2005 e proviene dal sito Hogan Claim.

La fluorescenza della calcite è spettacolare (sembrano braci ardenti). La fluorite e la willemite sono a volte accoppiate a formare una sorta di cinture bicolori.

C’è anche una piccola vena di smithsonite fluorescente viola e zone rosa per la sovrapposizione della calcite (rossa) e della fluorite (blu).

Alcune aree sono fosforescenti (willemite ed .... aragonite?)
