About OboyeriteHide

Oliver M. Boyer
Formula:
H6(Pb,Ca)6(Te4+O3)3(Te6+O6)2 · 2H2O
Colour:
Milk white
Hardness:
Specific Gravity:
6.4
Crystal System:
Triclinic
Name:
Named in 1979 by S.A. Williams in honor of Oliver Michael Boyer (15 November 1842, New Hope, Ohio, USA - 14 September 1918, Medford, Oklahoma, USA), prospector. In 1878 he discovered several rich veins of silver in mines near Tombstone. After killing a man, he was sentenced to death but in 1883 he was released on the condition that he leave Arizona. He then took up a life of farming.
