This show attracts a lot of very active Pennsylvania field collectors, so it's not surprising that this year there were specimens of the previously mentioned wavellite
Pearly white to capucine-orange mammillary masses of resinous, amorphous allophane form the matrix in some vauxite, vivianite and wavellite specimens.
Gordon (1944) described andorite in small, brilliantly metallic, striated, prismatic steel-gray crystals to 1 mm, all covered by wavellite, with stannite and pyrite on quartz.
Small, white, spherical, radial masses of wavellite
occurred at the Raven and Bertha B mines.
Llallagua phosphates, including childrenite, crandallite, fluorapatite, metavauxite, monazite, paravauxite, sigloite, vauxite, vivianite and wavellite
, were actively collected by Bandy.
A carbonaceous and sulfide-bearing shale horizon just barely exposed at the bottom of the northernmost pit of the Willard mine contains excellent wavellite, fluellite and minyulite.
It is the site of the first discovery of minyulite in Nevada; it has produced the world's largest crystals of fluellite and perhaps also minyulite; and it has furnished what are by far the finest quality specimens of wavellite, fluellite and minyulite ever discovered in the state.
He has collected brookite at Magnet Cove, Arkansas; wavellite
at Mauldin Mountain; quartz at Coleman's mine in Jesseville, Arkansas; blue barite at Stoneham, Colorado; pyrite at the Dallas-Fort Worth Airport; clear barite at Grand Junction; quartz at Herkimer, New York; red beryl at the Wah Wah Mountains in Utah; topaz and pseudobrookite at Topaz Mountain; and tourmaline at the Himalaya mine in California.
Goar, on the bank of the Rhine (where tour boats ply, bound for the Lorelei Rock, every day); who knows of the fine, bright, embedded spherules of yellow-green wavellite
, not from Arkansas or even Devonshire, but from quarries on Wachtelberg Hill near the village of Langenstriegis, west of Freiberg?
Wright's Rockshop had the best Maudlin Mountain, Arkansas, wavellite
I have seen in a long time.
Planerite occurs with wavellite
and variscite in the Bigfork Chert at Mauldin Mountain, near Mt.
