Oriented core resources

This page contains links to  oriented core material produced by Rod Holcombe. It includes a comprehensive manual dealing with orientation procedures and extracting useful structural data from oriented core.An early version of this manual was translated into Chinese and is also available here.
Other links are to printable wrap-around core protractors; and to one of my software applications [GeoCalculator], which can also recalculate geological orientations from structural core measurements.

Manual: Oriented core measurement and calculations

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