Description:
The intrusive rocks of Marston Jabet and Chilvers Coton, though probably of quite minor importance, have been rendered noteworthy by the variety of opinions held regarding their true position in a scheme of rock classification. This is especially the case as regards the rock quarried at Marston Jabet. Thus Allport comments upon certain remarkable features distinguishing this rock, which, however, seems to be covered by his general statement that the intrusive rocks of the Warwickshire Coalfield are for the most part ordinary diorites. Rutley concurs in the opinion expressed by Allport. Watts calls attention to the lamprophyric aspect of the rock, which he terms a camptonite; and with this description Harker agrees. Hatch admits the lamprophyric features and incidentally refers to the lack of recorded analyses.
