CorStruth - Automated Analysis of HyLogger Data from the NVCL

 
Melbourne Cup Day 2018
1. Moving towards putting HyLogger-2 Data onto CorStruth        
 2. New Holes: 39 from Queensland and 77 from WA.                       
3. Improving the Interpretation of HyLogger Data Using XRF     

HyLogger-2 data has now TIR measurements and there will need to be a new product format for the PNG files that CorStruth produces. Some test products are available for comment.

There are 77 new WA holes and 39 new Queensland holes on Corstruth. Some of the names of the WA holes have been revised to better match those used by the GSWA. Details of the changes are here.

I have been looking at how we can improve the interpretation of HyLogging data with XRF measurements. There is a note describing the results here.

The current CorStruth products are:
Interpretations (like the one opposite) suitable for A4 presentation with variable bin sizes.
Browser-based scrollable images with a standard bin size of 0.25 m. (e.g. here)
Downloadable CSV files of TSA+ and jCLST interpretations binned at 1 m intervals.
Mineral Occurrence Maps (MOMA's) of various minerals identified with the NVCL data

There are three ways to access the interpretation images. (See here for more details)

CorStruth's purpose is to provide automatic interpretations of the HyLogging data from every HyLogger-3 dataset acquired as part of the AuScope National Virtual Core Library (NVCL) program. The results are free for you to copy but remember that they have been produced by automatic algorithms which will make mistakes. In this regard make sure you read the notes under Cautions.

The NVCL program is a team effort and thanks are due to everyone involved  - both individuals and organizations. And here most of them are at the 2017 NVCL Workshop in Sydney.
