What reading level is British Petrography With Special Reference to the Igneous Rocks book?
To quickly assess the difficulty of the text, read a short excerpt:
The red hornstone differs from the pitchstone in being crypto-crystalline and in containing a large amount of colouring matter. It is interesting to note that the red colouring matter (ferrite) makes its appearance as soon as the matrix shows double refrac- tion, that is as soon as crystallization takes place. This agrees with the views of VOGELSANG and ROSENBUSCH that it is squeezed out of the magma during the process of crystallization.
The felsites of Arran vary considerably in character. So...me are compact and without porphyritic constituents ; others contain crystals of bipyramidal quartz, sanidine and plagioclase ; others again are markedly spherulitic ; the spherules being sometimes as large as small peas and so thickly set as to make up the bulk of the rock. The ground-mass of the felsite varies in colour from a bluish black to light grey or yellow. Under the microscope it is crypto- crystalline, micro-crystalline, confusedly crystalline or spherulitic. Sometimes there are traces of granophyric structure.
