Dear All,
Has anyone used image-analysis techniques to acquire mineral modes, say of igneous rocks? Is it reliable? I have heard that if the rocks are simple, it's as quick to do by eye. But if they are altered (yummy!) the human eye and brain are more reliable.
Secondly - grain-size analysis. I have heard of people scanning a section, and then using a PC to do the analysis by enhancing grain boundaries and then using grain centres. What sort of methods are available and who are the suppliers of any software required?
Many thanks for any advice.
