Sheer Zone Gold Class – Find Structurally-Controlled Gold in Sheared Rock Zones
⸻
Where the Rock Breaks, the Gold Moves.
The Sheer Zone Gold Class is your field-level training on how to prospect and profit from one of the most powerful gold-hosting structures on Earth: shear zones.
These tectonically active zones are where crustal blocks grind, shift, and deform—creating long corridors of crushed rock, quartz veining, and hydrothermal fluid flow. If you know how to follow them, shear zones will take you to gold that’s hidden in plain sight.
This class teaches you how to recognize the rock textures, mineral patterns, and alteration halos that point directly to productive shear-controlled systems.

🧭 What Are Shear Zones?
Shear zones are structural breaks in the Earth’s crust that accommodate deformation over time. Unlike faults, which can snap suddenly, shear zones often stretch, drag, and rotate layers of rock under pressure—forming long belts of aligned foliation, fault gouge, clay-rich slip surfaces, and often massive quartz intrusion.
Gold forms in these environments when mineralized fluids migrate along these weakened pathways and deposit metals where pressure drops or chemistry changes. They are common in greenstone belts, metamorphic terrain, and orogenic gold provinces.

🔍 What You’ll Learn in This Class
This playlist unpacks the physical, visual, and geologic characteristics that make shear zones such powerful prospecting targets.
1. Shear Textures and Host Rock Deformation
Learn how to recognize foliation lines, sigmoidal veins, sheared quartz, and mylonite—key indicators of ductile deformation and fluid movement.
2. Gold Traps in Shear Systems
We show you where gold concentrates:
• In jogs along the shear trend
• At brittle-ductile transitions
• Where shear intersects contacts or brittle faults
• At plunging ore shoots formed by structural rollovers
3. Alteration Along Shear Zones
Identify the red, yellow, and white halos that form as rock breaks down from mineral-rich fluids. Expect clay gouge, hematite staining, and chlorite or carbonate flooding.
4. Mapping and Sampling Strategies
Use flagging, strike/dip measurements, and trench crosscuts to sample across the zone and identify lateral or vertical movement of grade.
5. Reading Terrain for Shear Exposure
We help you use satellite imagery and topographic slope changes to identify faulted ridgelines, shear toes, and quartz-filled scarps in the field.

🧠 Why Shear Zones Matter
The most productive gold belts in the world—like the Abitibi Greenstone Belt in Canada or the Ashanti shear zone in Africa—are hosted in sheared rock. Even on a smaller scale, many Arizona and California hard rock claims sit directly on shallow shear trends that still hold rich pockets of untouched ore.
Shear zones act like mega-cracks in the crust: long-lived, fluid-carrying, and incredibly effective at concentrating gold in predictable places.
This class helps you tap into that predictability—so you stop swinging blind and start following structure.
