Unknown carbonate Pike Quarry, Hooksett, NH 6 mm field of view. Individual crystals are about 0.5 mm.	Species: Unknown carbonate Locality: Pike Quarry, Hooksett, NH Specimen Size: 6 mm field of view. Individual crystals are about 0.5 mm. Field Collected: Tom Mortimer - 2014 Catalog No.: 1898 (e.g.) Notes: This unknown carbonate gives moderately strong fizz in muriatic acid. These saddle habit rhombs are similar to those of dolomite and ankerite. They are not fluorescent.

GALENA with SPHALERITE Pike Quarry, Hooksett, NH 4 cm specimen. Embedded square galena crystal cleavage in sphalerite in white quartz	Species: GALENA with SPHALERITE Locality: Pike Quarry, Hooksett, NH Specimen Size: 4 cm specimen. Embedded square galena crystal cleavage in sphalerite in white quartz Field Collected: Tom Mortimer - 2014 Catalog No.: Notes: The lusterous silvery galena did not reproduce in this photo. However the square outline of the galena crystal is evident.
KAOLINITE Pike Quarry, Hooksett, NH 9 cm specimen	Species: KAOLINITE Locality: Pike Quarry, Hooksett, NH Specimen Size: 9 cm specimen Field Collected: Tom Mortimer - 2014 Catalog No.: 1902 Notes: Feldspar altered to soft, white, kaolinite, (easily scratched with fingernail). Only a species collector would bother with this!
ORTHOCLASE var. Adularia Pike Quarry, Hooksett, NH 6 mm field of view	Species: ORTHOCLASE var. Adularia Locality: Pike Quarry, Hooksett, NH Specimen Size: 6 mm field of view Field Collected: Tom Mortimer - 2014 Catalog No.: u1480 (e.g.) Notes: The backside of this specimen has micro quartz crystals with blue anatase. At the Hookset Quarry, anatase is only VERY rarely found on adularia, rather almost always on the micro quartz.
PREHNITE ? Pike Quarry, Hooksett, NH 2 mm string of milky rhombic crystals.	Species: PREHNITE ? Locality: Pike Quarry, Hooksett, NH Specimen Size: 2 mm string of milky rhombic crystals. Field Collected: Tom Mortimer - 2014 Catalog No.: NC Notes: First thought was that these were calcite, but gave NO fizz in muriatic acid. Given presence in basalt amygdule void, chabazite is good guess....but a Bob Wilken reminded me chabazite will slowly decompose to a gel in HCl. No decomposition was observed after several hours. The remaining prime candidate would seem to be prehnite.
PREHNITE ? Pike Quarry, Hooksett, NH 0.5 mm cluster of milky rhombic crystals..	Species: PREHNITE ? Locality: Pike Quarry, Hooksett, NH Specimen Size: 0.5 mm cluster of milky rhombic crystals. Field Collected: Tom Mortimer - 2014 Catalog No.: u1481 Notes:

TITANITE Pike Quarry, Hooksett, NH ~ 0.45 mm crystal TITANITE Pike Quarry, Hooksett, NH 0.34 mm crystal	Species: TITANITE Locality: Pike Quarry, Hooksett, NH Specimen Size: ~ 0.45 mm crystal Field Collected: Bob Wilken Catalog No.: An Anna Wilken specimen. Bob WIlken photo Notes: [bw] In the course of retaking the Pike Hooksett titanite photo I decided to do a comparison of how different the result can be depending on whether I put the specimen inside the ping pong ball or if I put the ping pong balls over the LED lights. You can see how the first way dulls luster and prevents light from penetrating the crystals. The second way you really see the crystals more like the eye sees them through the scope. But, often there is the tendency for the latter method to end up with flaring. It didn't in this case although the two little stripes on the end of the narrow crystal are quite bright. With masses of numerous reflective crystals, the ball over the specimen is the best way to go but at a sacrifice.
Unknown green-blue crust Pike Quarry, Hooksett, NH 5.5 cm specimen	Species: Unknown green-blue crust Locality: Pike Quarry, Hooksett, NH Specimen Size: 5.5 cm specimen Field Collected: Tom Mortimer - 2014 Catalog No.: NC Notes: No fizz in muriatic (not a carbonate). Not soluable in acetone => not an organic paint. Not water soluable. Green-blue color and tests suggest a copper sulfate or a copper-zinc sulfate.
Unknown yellow ball Pike Quarry, Hooksett, NH 0.3 mm UK yellow spherical masses, left	Species: Unknown yellow ball Locality: Pike Quarry, Hooksett, NH Specimen Size: 0.3 mm UK yellow spherical masses, left Field Collected: Bob Wilken - 2014 Catalog No.: A Bob Wilken specimen Notes: [bw] The nature of the two to the left is of foliated sheets. Could be mica? The ones to the right are vitreous and I catch a distinct triangular reflection at least in one place. Could be poorly formed ??? Odd that the same color spheres would be two different minerals so close together. The foliated group of two combined is 0.3 mm.
