Fractured knowledge

This brief blog post is a response to a recurrent question that comes from exploration and mine geologists. The question is ‘what is a fracture?’

Strain? What strain??!

The majority of geologists don’t understand 3D ductile strain, judging from our consultations with clients. I explain why it is absolutely critical to understand ductile strain to benefit exploration and resource evaluation.

Structure at the expense of geology

The analysis of mineralisation occurrences requires an integrated approach that should include all facets of geology, not just structure. In this post I talk about how to display this information in a small convenient format – the paragenetic table.

What is a Fault?

Many geologists consider the modelling of faults in mineral deposits to be VERY important. I am not one of these geologists. To understand why I feel this way, you have to ask the question “What is a Fault?”

Boundary Analysis in Leapfrog

How do you decide whether to make a fault boundary hard or soft? Geologist Ron Reid, who is an Orefind-trained veteran Leapfrog user, explains how to do this effectively in Leapfrog Mining software.

Drill core orientation – An Inconvenient Truth (Part 3 of 3)

Obtaining reliably oriented core at the rig is only the first step in the process of dealing correctly and efficiently with oriented core. Individual orientation marks need to be checked and orientation lines constructed from those of high confidence. This post looks at processes and problems associated with checking orientation marks, constructing orientation lines, measurement of data and recognition of problems in data distributions

The Watch Riddle

A parable is a short tale that illustrates universal truth.
Today’s post is a geological parable in two parts, and it starts off with a strange looking watch.

Drill core orientation – An Inconvenient Truth (Part 1 of 3)

The mining and exploration industry spend too little time interrogating the data that is most routinely used. Unusable structural data is commonly taken from oriented core yet incorporated into exploration and mining studies, which may result in severe consequences. Brett Davis, in part 1 of three posts, discusses common drill core orientation problems and what to do about them.
