It is generally supposed that the crystalline limestones which occur amongst the schists, associated with orthogneisses, in various parts of the world, are altered sedimentary limestones whose accessory minerals and crystalline structure have been developed by simple contact and dynamo-metamorphism; and no doubt many crystalline limestones are of sedimentary origin, and owe their peculiarities to these agencies. In other cases the peculiar mode of occurrence of such rocks or their manner of association with igneous rocks (orthogneisses or nepheline-syenites) has led to the suggestion of other theories.
