Arsenopyrite from
Ackerman mine, Marmora Township, Hastings County, Ontario, Canada


Locality type:Mine
Classification
Species:Arsenopyrite

Comments:Specimens exhibit a variety of habits including bowtie twins (rare, 5mm the largest we have found). Specimens are usually etched out of the matrix with acid but the odd good matrix piece can be found. Largest single crystals found by us in 1994 are 25mm x10mm.
Gold is occasionally found on the arsenopyrite crystals.

This locality is now posted and the Ontario Provincial Police do check out parked vehicles! It is also rife with poison ivy.
Quality for species:Good crystals or rich for species - important (!)
Abundance at site:Very common
