Extract

In describing the chief assemblages of the Scawt Hill contact-zone in Co. Antrim brief reference was made to the occurrence of wollastonite and xonotlite associated with the flint nodules of the contact-altered chalk. A more detailed examination of these nodules has now been made and the study of a large number of examples has revealed an interesting group of mineral assemblages which have developed by a progressive metasomatism of these siliceous bodies.
