Joselyn Mcphie et al. produced this amazing text on interpreting volcanic textures in the field.
No exploration geologist should be without. And it’s more than just interpreting volcanic textures- they outline a great method of describing any rock a geologist might find in the field, using a common terminology and method. Go beyond tuff (interpreted- tells us nothing), instead describe it as a ‘fine-medium grained plagioclase-lithic clastic’, and your geologic understanding of complex terrains will evolve overnight.
