Learn geological modelling: guides, glossary and case studies
GEOREKA Learn is the hub of guides, glossary entries, case studies and migration help for geologists who model deposits and estimate resources in 3D.
Use the glossary for a quick definition, a guide for a complete answer to one method question, a case study to see a workflow with its outcome, and the switching page if you are moving from another modelling package. Every guide links to the GEOREKA feature that applies the method.

Glossary
Short, citable definitions of block model, kriging, variogram, compositing, domain, JORC and more.
Guides
One question per guide: a four-part introduction to estimation, domains, local varying anisotropy, validation, simulation, classification and more.
Case studies
How geologists model deposits and estimate resources with GEOREKA, with the outcome in numbers.
Switching from Leapfrog
What to compare, how to move a project across, and a free guide to download.
Popular guides
Start with these guides
Resource estimation explained
Part 1. From a simple average to a weighted average, with no maths beyond one formula.
Signed distance functions
What implicit modelling really estimates, and why SDFs are flexible and fast.
Local varying anisotropy
Why one search ellipsoid is a compromise, and how a local anisotropy field follows the structure.
Common questions
Learn FAQ
Where do I start if I am new to geological modelling?
Start with the four-part introduction to resource estimation, and keep the glossary open for definitions. Then try a 14-day trial on your own drillhole data.
Are the guides specific to GEOREKA?
The guides explain the methods in general terms first, then show where GEOREKA applies them. You can use them with any modelling software.
Can I download a guide?
Yes. The switching page has a free downloadable guide for geologists moving from Leapfrog Geo.
