Recently listed online by Roberto Rojas of Minerat minerals is a remarkable specimen of kröhnkite & blödite from Coronel Manuel Rodriguez Mine, Mejillones, Antofagasta, Chile.
At 25cm across the bright blue kröhnkite would be impressive in its own right, but Roberto's piece has a little sting in its tail.
About half way across a scorpion has become trapped and set in mineral surface partially obscured by a later deposition of blödite.
Scorpions are quite common in Northern Chile and are found in the darker recesses of mine workings and outcrops, another reason to wear gloves when collecting!
Roberto Rojas has been a seller on e-Rocks since 2009. By profession he is a geologist and is a frequent visitor to the mining areas in and around Atacama.
His collecting trips are often long duration to some fairly obscure places, but these have rewarded both him and us with a super selection of rare and colourful Chilean minerals - however this is his first arachnid and mineral combo!!
