.	Dwarves' Earth Treasures Online Museum: Laurium Datolites Laurium Mine, Laurium, Houghton Co., Michigan	.

.    Laurium Mine is one of very few mine dumps which I know excatly where to find datolites. I have quite a short story to tell about those unusual datolites I found at Laurium Mine. On August 2004, I was just walking over the bulldozed mine dump of Laurium Mine (behind a church) with my eyes on the ground as always, and I happened to easily spot a datolite in plain view (how can anyone have missed that one?!), but I was running out of time to search for more.
     Next year, I came back to the excat spot where I found the first datolite, and just 40 minutes later (according to someone else who was with  me), I already found three more datolites (not counting a clip). Again, I found two more datolites in August 2006 and another one (possibly last) in August 2007. It was obvious that the miners hit on a single datolite seam and dumped the datolites on one spot.
    The unusual thing about the Laurium datolites is that they contain "mossy" flicks of copper (think of moss agates) that make those datolites look rather red-brownish, and one black datolite had been found too.
 

First datolite I found at Laurium Mine  and it was in plain view! August 2004	Check out the mossy details  of copper in this specimen!  Angust 2005
The ghosty white areas are actually  fractures just beneath the surface. August 2005	This one was found in the bulldozer's  tracks, hence it was very fractured. August 2005
