Short summary
Natrolitised Early Cretaceous metaplutonites (melteigites, ijolites) contain various accessory minerals. The natrolitisation was a very low-temperature process, which did not affect most of the primary minerals, including most of the accessories. The evidence shows the release of barium and strontium, possibly from feldspathoids, from primary Na–Ca feldspars, and optionally also from glass, during the natrolitisation.
