Description

Detailed Description

This specimen features two chabazite penetration twins at the top, centre, associated with smaller chabazite crystals and small white heulandite crystals. The chabazite crystals are sharp and lustrous. In excellent condition – a tiny chip on the back of the left corner of the left top crystal (not obvious as displayed) and some incomplete crystals along the lower edge. Stands perfectly for display as photographed. Good colour and the heulandites provide a good contrasting rim – a very nice red chabazite.

About These Red Chabazites From Wasson’s Bluff

In one relatively small zone at Wasson’s Bluff, the chabazite crystals are a particular dark red hue – more intense and lighter than a brown, and most are a bit deeper and darker than a brick red or deep orange. This zone has produced sporadically over history. Most often, days of very hard work in this area yield absolutely nothing, but a few isolated finds in recent years have produced a small number of excellent pieces – these specimens are from those finds. There have been no finds from this zone since 2017.

In historic times, these particular deep-coloured chabazites from Wasson’s Bluff were known as “acadialite”, named for Acadia (which is the English for L’Acadie, the colonial-era name for this part of Canada). The name “acadialite” is sometimes still seen on older collection labels, sometimes as a species name and sometimes as a varietal name. Under current nomenclature, these specimens are known as chabazite, with “acadialite” now considered a historical synonym.
