Petrology, the study of rocks, is a vast and dangerous expanse full of deep Olivine cravasses, mica lakes and pyroxene swamps. Will you recognise them? Will petrology be the death of you?

Mackenzie and Guilfords book, along with Deer Howie and Zussman is an exceptional reference. All the key minerals that the degree level student will come across in thin section, are dealt with - their pleochroism , their relief and texture. In addition, some common mineral assemblages are also reviewed.

I would have drowned during my Petrology lessons without this book - other students will know that Dr Speedyman is only so good!

If you only buy one Petrology book, buy this one. The Atlas of Rock-Forming Minerals in Thin Section is your Petrological Bible.
