Advance guide how to make geological thin sections
A downloadable Advanced Guide to Preparing Geological Thin Sections of Challenging Samples. A instant downloadable PDF file. Since retiring as a University Lecturer, I have set up a rock preparation lab in a garden office, preparing standard thin sections without the need for costly and bulky thin-section machines. In the Beginners Guide to How to Set Yourself Up and How to Make Geological Thin Sections at Home, I covered the standard thin section preparation of straightforward rocks due to their consolidated and durable nature. However, difficulties arise when working with friable, porous, or highly cleavable rocks such as poorly cemented sandstones, shales, slates, schists, and chalk. This advanced guide outlines thin sectioning techniques developed over 40 years of thin section preparation experience, addressing the challenges of difficult samples. It also includes techniques for preparing grain mounts from separated mineral grains.
