This piece features a great penetration twin of chabazite, surrounded by chabazite crystals, some of which are also twinned. The chabazite crystals are sharp with good lustre. Upon close examination, one can see a bit of colour-zoning, into almost a honey-golden hue in a couple of places. In excellent condition, no damage to the main crystals, and some incomplete crystals around the periphery where this was attached to surrounding rock.
A great chabazite twin, nicely situated among the accompanying crystals.
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.
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.
