Dwarves' Earth Treasures Online Museum: Franklin & Franklin Jr. Datolites
Franklin & Franklin Jr. Mines,
Hancock, Houghton Co., Michigan
.
.
Franklin Mine is one of few mines to work on the Pewabic Lobe north of
Houghton and Pewabic lobe is renowned for producing some of the most colorful
datolites coming from Michigan. Two shafts were opened at Franklin but
got boxed in by Quincy companies, forcing the mine to extend northeastern
by opening several shafts of Franklin Junior mine. Franklin have produced
some really colorful datolites which red, yellow, orange colors are included
and few examples have came with a mixture of yellow and red colors. But
now, the mine piles already have been hauled away for rock crushing and
there is no hope for finding any new datolites from the piles. Despite
opening of several additional shafts, Franklin Junior mine is not well
known for its datolites, but few white mult-chambered with greenish "mossy"
inclusions have been found from one of the mine piles recently.
