The occurrence of the rare barium zeolite harmotome at Pen-y-Clun Mine is
thought to be only the third locality for the mineral in Wales
In addition to the rare British species mottramite and vanadinite, Judkins
Quarry also yields some interesting and extraordinary forms of lead and copper
sulphides.

Chalcopyrite: tarnished replacements of acicular chalcopyrite to 10 mm. Roy Starkey specimen.
Milltown Quarry is the type locality for sweetite and ashoverite - two of the four known naturally occurring polymorphs of zinc hydroxide, all four of which occur here.

Litharge pseudomorphs to 1.5 mm.
The Republic of Ireland has a richly varied geology, is well endowed with
mineral resources, and has been a source of fine mineral specimens for two
centuries or more.

Chalcomenite: Ballybunnion, Co. Kerry. Largest spray is ca. 0.5 mm across. Collected by R. Barstow. George Ryeback specimen.
Held each year on the first weekend in July, France's premier mineral show,
at Ste-Marie-aux-Mines in the Voges Mountains of Alsace, is Europe's most
cosmopolitan mineralogical event.

Rhodochrosite: 22 mm. Chacao, Peru. Barras Gauthier Minéraux
Re-discovery of one of Heddle's zeolite sites at Sgurr nam Boc confirmed
that, although access to the site is difficult, high quality specimens are
still available.

Stilbite 40 mm.
Hendre quarry was first visited by the authors in 1984 in search of pectolite and apophyllite, following a lead from a museum specimen. This search was unsuccessful, but instead yielded and interesting suite of minerals including anatase, apatite, brookite, rutile, monazite-(Ce) and xenotime-(Y).

Anatase: sceptre crystal 1.5 mm long. Neil Hubbard specimen.
