Chris Tucker Minerals
Specializing in minerals from Montana

On this page you will find bulk micro rough and mounted micros (coming sometime in the future!).  If you don't see what you are looking for, let me know.  I generally have micro specimens and rough from any locality on this site.

Important, READ the following!
Generally these are fist sized pieces, in the one pound range, with at least one vug (often several) exposed, perfect for that mini collecting trip with your microscope, expect to get at least one full pound of material.  Minerals listed are know to occur at the locality but may or may not be present in the particular piece.  Those minerals followed by the letter "C" are common and should be expected to be present, those followed by the letter "S" are sparingly present at the given locality and may or may not be present, those followed by the letter "R" are rare at the locality and should not be expected to be present.  To order, simply email me at chris@christuckerminerals.com with the locality and quantity that you desire.  

New!
Rat's Nest Claim, Custer County, Idaho.   $6.00
Heulandite-Ca  S
Heulandite-Na  C
Mordenite  S

Mostly thin flattish pieces with small vesicles that reach 6-7mm in size which are lined with crystals of heulandite-Na and are occasionally topped with microcrystals of other species.
 

SOLD OUT!
Black Pine Mine, Granite County, Montana  SOLD OUT!!! for a full USPS flat rate box to USA addresses.

The above list is the most complete list of species known to occur at the Black Pine mine.  The bulk micro material is all dump material, and it is therefore impossible to predict which species are present.  Certainly, most of the above species will not be present in the boxes of bulk micro material, but perhaps you will get lucky.

New!
Near Dillon, Beaverhead County, Montana  $4.00
Heulandite C
Mordenite R
Goethite R

Heulandite (probably heulandite-Ca) is fairly common in this material and occurs as simple colorless crystals in the 1mm range.  The host rock is light so expect to get a bunch.

Wapiti, Park County, Wyoming  $5.00
Analcime R
Heulandite C
Mordenite C

Fairly vuggy material often with only a few crystals per vug.  Heulandite as colorless transparent crystals along with mordenite in its usual habit.  Very pretty beneath the microscope.  Analcime is present as larger 5-7mm crystals and only occurs in large vugs.  This material has not been analyzed but I suspect that it is all Ca rich.  Only a few pounds remain!

Spearfish Canyon, Lawrence County, South Dakota. $7.00
aegirine C
analcime C
apatite S
barite S

Thin smallish cavities in phonolite.  Barite is the real prize here and it occurs as complex prismatic colorless crystals.  Other minerals are probably present.
