Oriented Core Measurement and calculation procedures©

 

Pdf file that includes full description of oriented core procedures; including extracting structural information from unoriented core; instructions for manual stereographic plotting of core data; bias and error detection; QA/QC procedures; and some stereographic analytical procedures [~5Mb] [Last modified:Aug 22, 2017]

[Much, but not all, of this manual is included as Chapter 9 in the text: Mapping and Structural Geology in Mineral Exploration]

This link [~4.8Mb) is to a Chinese translation of the above [translated by Zhu Fengsan, organised by Greg Hall]. Note that this Chinese version is of an earlier edition than the English language version above.
