Yeh, "One-pot synthesis of hollow Au3Cu1 spherical-like and biomineral botallackite
Cu2(OH)3Cl flowerlike architectures exhibiting antimicrobial activity," Journal of Physical Chemistry B, vol.
, a rare copper chloride trimorphous with atacamite and paratacamite, was named for the Botallack mine, Cornwall, England, where the first specimens were found in 1865.
Over in the Arkenstone (www.irocks.com) booth, Rob Lavinsky had just three specimens (respectively 6, 10 and 12 cm across) representing Michael Merry's April 2007 find of botallackite
at Cligga Head, Perranzabuloe, Cornwall, England.
Wayne and Dona Leicht (of Kristalle) and Ian Bruce (of Crystal Classics) said that they had a new find of botallackite
from the Cligga Head mine, Perranporth, Cornwall, England.
Relationship to other sp ecies: It is chemically related to belloite, atacamite, clinoatacamite, paratacamite, botallackite
, simonkolleite, calumetite, anthonyite, claringbullite and eriochalcite.
In the presence of water belloite converts within minutes to botallackite
