The accurate analysis of an igneous silicate rock is a task beset with difficulties and one which, on account of the very complete analyses now required by petrologists, involves the expenditure of a considerable amount of time. The advantages which accrue from the performance of quantitative analytical operations on the micro-scale are becoming more and more apparent, and the application of at least semi-micro-analytical methods to rocks was thought to have profitable possibilities, particularly in the way of hastening the analyses.
