Locality: Turner Mine, Marlow, NH
Specimen Size: 1.9 mm longest dimension
Field Collected: A Bob Wilken specimen (collected 10/20) & photo
Catalog No.: TURCassiterite01AS
Notes: [bw] "This cassiterite was embedded between a hard quartz matrix behind and a soft layer made mostly of fine mica and quartz granules in front. Unknowingly when sawing for something else the saw blade missed it it by a hair or two and exposed part of the crystal duo. I picked away as much of the rest as I could to pretty much reveal the specimen as you see it. My first reaction without any critical observation was to think it a phosphate. But, the color and the vitreous nature eventually made me realize it could be cassiterite. The unusual flattened form just didn't fit with what we usually find as cassiterite."
