Basic for geology

This book (written by my mother) analyses the vocabulary of geology and distils from it the 50 most commonly used words. These, together with the 100 words for general science and the 850 words covering general useage, 1,000 in all, can be used in transliterating any standard work on the science of geology such that it will be uniformly and unequivocally understood internationally by anyone working or studying in the field.
