Birch Mountains kimberlite field, Kimberlite field in northern Alberta, Canada.
Birch Mountains kimberlite field contains eight volcanic pipes scattered across remote north-central Alberta. These pipes formed during the Late Cretaceous period and are buried beneath thick layers of sediment.
Geological surveys in the 1990s revealed the existence of this kimberlite field in northern Alberta. The volcanic structures date back to the Cretaceous period approximately 80 to 90 million years ago.
The field's mineral exploration activities require careful coordination with Indigenous communities who maintain traditional land use rights in the area.
The site sits in a remote area accessible only with special permits and equipment. Reaching this location demands careful planning and coordination with local authorities.
The pipes contain diamonds and microdiamonds within a grey-green matrix of serpentine, calcite, and dolomite. This mineral composition makes the field valuable for diamond exploration research.
