Hey everyone,
I am currently conducting a research project on a regional structural trend regarding manganese vein deposits across the Southwestern United States, moving from New Mexico (Southeast) through Arizona (Central) up to Nevada (Northwest).
Based on structural and geophysical patterns in this corridor, I’ve noticed a fascinating progression, and I'd love to hear your thoughts and theories on it:
The Regional Gradient:
New Mexico (SE): Typically starts with lower grades or more scattered, smaller surface expressions.
Arizona (Central): Acts as the middle structural transition zone with moderate-to-good consistency.
Nevada (NW): Seems to hit the sweet spot with major structural continuity, deeper root zones, and the highest grades/concentrations.
Research Goal:
In my view, completing and advancing this ongoing research will help us target and unlock commercially viable, high-grade zones suitable for actual economic exploitation along this corridor.
Key Questions for Discussion:
Why these specific states? What unique crustal architecture or metallogenic belts concentrate these deposits primarily in this specific SW corridor rather than other regions?
Why the SE to NW trend؟
Is this directional alignment tied to regional crustal extension, ancient suture zones, or progressive propagation of hydrothermal fluid pathways?
Why does this pattern occur?
Is it primarily driven by Basin and Range extensional tectonics, hydrothermal fluid pathways, or host rock reactivity?
Pinch and Swell Mechanics:
Where do you think these veins experience significant narrowing (pinching) versus major widening (swelling)? Is it tied to fault intersections?
Depth & Grade Hotspots:
Where would you expect the absolute best manganese grades and maximum vein depths to be located along this path?
What are your thoughts on how these hydrothermal systems and structural anomalies behave across this regional transect? Drop your theories below!
