This specimen hosts sharp, lustrous red chabazite crystals, including prominent penetration twins. In excellent condition, some incomplete crystals at the outer periphery where this was attached to surrounding rock.The piece has been stabilized (not visible as displayed), solidifying it from behind. There are small pearly heulandite crystals at the right edge. 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.
