Sectional Digitisation
Why I Give Geological Cross-Sections the Cold Shoulder
In this post, I question the usefulness of a geological habit universally accepted as a good thing—the geological cross-section
Read MoreA recipe for shrinking a mineral resource by 90%
How can a mineral resource be downgraded by 90%? This is a simple explanation most geologists are not aware of.
Read MoreThe devolution of the Leapfrog drawing tool – a lesson in designing disruptive technology: Part 2
The 3D drawing tool in Leapfrog released in 2004 cannot be faulted from a technical standpoint. So why wasn’t it included in the next generation of Leapfrog software, Leapfrog Geo?
Read MoreStrain? 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.
Read MoreThe myth of sectional geological modelling: Part 2
I outline the quickest way to model geology in 3D, but it’s controversial and the discussion may offend the majority of academic economic geologists!
Read MoreThe myth of sectional geological modelling: Part 1
“Interpreting in section and in plan is the most reliable way we can understand the geology of the deposit.”, or is this statement a myth?
Read MoreWill Gemcom produce a Leaped Frog out of Leapfrog?
Gemcom recently announced the ‘Dynamic Shells’ update to their Surpac software, which is described as a fast implicit modeller. This is a module that jumps and croaks like Leapfrog, and regardless of whether it actually works like Leapfrog is a moot point. It doesn’t really matter because in marketing, it’s all about perception.
Read MoreIs sectional digitisation in geological modelling still considered “industry best practice”?
For geological modelling, resource geologists generally favour the use of sectionally hand-digitised wireframe models for resource estimation, but in 2012 is this still considered industry best practice? Jun Cowan, the conceptual founder of Leapfrog software, discusses this issue with a familiar example.
