Calcite + analcime. A gorgeous brown group of slightly curved rhombohedral calcites, in a vug lined with small (2mm) analcime crystals. The calcites are very lustrous, and rather difficult to photograph ! Vug measures 36mm high x 25mm wide. Self-collected 1999 from Talisker Bay, Minginish, Isle of Skye. (Author: Mike Wood)

Calcite + chabazite + analcime Talisker Bay, Isle of Skye, Scotland, UK Calcite crystals 25 mm Honey-brown spike of rhombohedral calcite crystals 25mm long stands in a vug (35mm x 20mm) lined with small twinned pinkish chabazite crystals and a single white analcime crystal (3mm). Self-collected 1992 from Talisker Bay, Isle of Skye. (Author: Mike Wood)

Calcite + chabazite. A nice ’floater’ specimen of transparent yellowish calcite with a matt surface, on lustrous chabazites. Specimen is 23mm high x 20mm x 17mm. Self-collected 2009 from Moonen Bay, Isle of Skye. (Author: Mike Wood)
-
Calcite + chabazite. A not-so-good photo showing a nice yellowish transparent calcite rhomb to 15mm on edge, on a bed of small chabazite crystals. Specimen is 50mm x 25mm x 22mm. Self-collected 1999 from Moonen Bay, Duirinish, Isle of Skye. (Author: Mike Wood)

Calcite + stilbite Biod a’ Mhurain, Duirinish, Isle of Skye, Scotland, UK The plate measures 22 cm x 13 cm Very large plate covered on both sides with simple calcite rhombs to 5mm, on a layer of micro stilbite crystals (which are much more exposed on the back of the specimen). Several groups of large pale yellow interpenetrant calcite rhombs are perched aesthetically on the specimen. The plate measures 22cm x 13cm. Self-collected, in the company of Dave Green, 1997 from Biod a’ Mhurain, Duirinish, Isle of Skye. (Author: Mike Wood)

Calcite + stilbite Biod a’ Mhurain, Duirinish, Isle of Skye, Scotland, UK The large calcites 29 mm on edge A beautiful specimen of transparent, slightly etched rhombohedral calcite with some modifications to the corners and edges. The large calcites (to 29mm on edge) rest on a bed of micro stilbite crystals and a few simple calcite rhombs. This is the first specimen I found at this locality; it was exposed to the atmosphere and colourless. The other calcites found within the cavity have a yellowish hue. Self-collected 1996 from Biod a’ Mhurain, Duirinish, Isle of Skye. (Author: Mike Wood)
-
Calcite + stilbite Biod a’ Mhurain, Duirinish, Isle of Skye, Scotland, UK Specimen is 75 mm x 45 mm Calcite crystal 20mm wide An interpenetrant rhombohedral calcite crystal 20mm wide is perched aesthetically on a bed of simple calcite rhombs (to 4mm), on a thin bed of micro stilbite crystals. Specimen is 75 mm x 45 mm. Self-collected 1997 from Biod a’ Mhurain, Duirinish, Isle of Skye. (Author: Mike Wood)
-
Calcite + stilbite Biod a’ Mhurain, Duirinish, Isle of Skye, Scotland, UK Calcite crystal 33 mm A large interpenetrant rhombohedral twinned calcite crystal 33mm wide is perched aesthetically on a bed of smaller simple calcite rhombs, which are in turn deposited on a thin layer (1mm) of tiny stilbites. The calcites are mostly dull with surface etching or coating but are transparent otherwise. Found at a very remote locality on the Duirinish peninsular. This specimen and the next three specimen photo’s all came from the same large vein cavity, in basalt lava. Self-collected 1997 from Biod a’ Mhurain, Duirinish, Isle of Skye, Scotland. (Author: Mike Wood)
-
Calcite + stilbite Camas na h-Uamha (Bay of Caves), Duirinish, Isle of Skye, Scotland, UK Specimen is 75 mm wide and 55 mm high. This specimen is from a different locality, though again it was in a vein cavity in basalt. There are THREE different forms of calcite here, though only two are represented on this specimen. The earlier scalenohedral calcites are coated with micro-crystallised stilbite, with simple later calcite rhombs on top; a rather beautiful combination. Specimen is 75mm wide and 55mm high. By the way, that calcite scalenohedron near the bottom left that sticks out leftwards - is stuck back on - in this case it was probably an unnecessary repair! Self-collected 1998 from Camas na h-Uamha (Bay of Caves), Duirinish, Isle of Skye. (Author: Mike Wood)
-
Calcite + stilbite. An elongated scalenohedron of calcite 64mm long is coated with micro stilbites, with a few rhombohedral calcites aesthetically perched on the larger crystal. Self-collected 1999 from Camas na h-Uamha, Duirinish, Isle of Skye. (Author: Mike Wood)
-
Calcite + stilbite. Basically a rhombohedral habit of transparent calcite, but elongated, into thin crystals, on a bed of stilbite. Specimen measures 55mm wide x 40mm high x 30mm deep. Self-collected 1994 from Sgurr nam Boc, Minginish, Isle of Skye. (Author: Mike Wood)
-
Calcite + stilbite. Nice yellowish rhombohedral calcite crystal to 15mm on the front edge, associated with small white stilbite crystals. Specimen is 37mm wide x 20mm high x 20mm deep. Self-collected 1992 from Sgurr an Duine, Minginish, Isle of Skye. ( Sgurr an Duine is the cliff/beach immediately north of Sgurr nam Boc.) (Author: Mike Wood)
-
Calcite + stilbite. Same specimen as Skye Minerals 094 seen previously, from a slightly different angle. Specimen is 58mm high and 80mm wide from this angle. Self-collected 1998 from Camas na h-Uamha, Duirinish, Isle of Skye. (Author: Mike Wood)
-
Calcite + stilbite. The only decent specimen showing the third habit of calcite at this locality. A ’butterfly’ twinned and flattened scalenohedral crystal measuring 25mm x 19mm is partially coated with micro stilbites, as is the more common elongated scalenohedral ’dog-tooth’ habit of crystal. The later more simple rhombohedral calcites appear to have been deposited after the earlier forms af calcite were covered with the micro stilbite crystals. Specimen measures 80mm wide (not all shown in the photo) x 45mm high x 40mm deep. Self-collected 1998 from Camas na h-Uamha, Duirinish, Isle of Skye. (Author: Mike Wood)
