Geochemistry

Hyperspectral

QA/QC Series

Geochemistry is a hard field to break into and even harder when mentors are hard to find. An initiative at LKI Consulting is to help young geochemists and those with an interest in the field to navigate geochemical principles and master the basics. 

This page is in memoriam of one of our mentors and is further dedicated to mentors everywhere.

Geochemistry

3D Lithogeochemistry Webinar: Part I

Join us as we partner with Imdex and Seequent to explore the interpretation of a historic geochemical dataset from Canada’s Flin Flon VMS district. In Part I of this webinar series, we dive into analyzing the data in ioGAS and look at first pass modeling with Leapfrog Geo. Along the way, we highlight the common challenges and pitfalls we encountered, offering valuable insights for anyone working with complex geochemical and geological datasets.

3D Lithogeochemistry Webinar: Part II

In Part II of this 3D lithogeochemistry webinar series with Imdex and Seequent, we take our lithogeochemical interpretations from the Flin Flon VMS district and integrate them into a comprehensive 3D geological model in Leapfrog Geo. Building on Part I, this session demonstrates how to enhance 3D models with lithogeochemistry, offering practical insights for complex geological settings with legacy datasets.

Geochemistry & Hyperspectral: Better Together

In this Geohug webinar, we go back to the basics of geochemistry and hyperspectral data, helping you gain a deeper understanding of these datasets. Learn how these powerful technologies complement each other and why integrating them enhances geological interpretation and decision-making.
