Lode
Mineralised fissure or linear zone, particularly in Cornish mining; existence does not imply present economic viability.
Language and route: Inherited English mining word lode, associated with an ore-bearing course or vein; distant Germanic roots need separate linguistic verification.

Literal gloss: ore-bearing course / vein
The name and its history
Mining communities across Britain, especially Cornish underground practice · pre-scientific mining vocabulary; earliest use unresolved
- What does the word literally mean?
- Immediate linguistic pathway: Inherited English mining word lode, associated with an ore-bearing course or vein; distant Germanic roots need separate linguistic verification. Relevant original form: lode (lode); conventional gloss ‘ore-bearing course / vein’. The linguistic gloss should not be mistaken for the original scientist’s stated motive unless directly demonstrated.
- What did the original author mean?
- Cornish miners mapped lodes, caunter lodes and crosscourses as practical subsurface targets before modern ore-genesis theories.
- Why was the name needed?
- To locate and work persistent ore-bearing zones, record their orientation and distinguish them from adjacent barren rock.
- What evidence supported the original concept?
- Underground ore distribution, strike and dip, quartz veins, crosscutting relationships and mine plans.
- How has geology changed the concept?
- Economic geology distinguishes mineralised veins, replacement and complex shear-controlled bodies; ore grade and genesis require analysis beyond the word lode.
Further historical context
Cornish miners mapped lodes, caunter lodes and crosscourses as practical subsurface targets before modern ore-genesis theories.
To locate and work persistent ore-bearing zones, record their orientation and distinguish them from adjacent barren rock.
Underground ore distribution, strike and dip, quartz veins, crosscutting relationships and mine plans.
Economic geology distinguishes mineralised veins, replacement and complex shear-controlled bodies; ore grade and genesis require analysis beyond the word lode.
Editorial qualification
It is inappropriate to attach a single inventor or Cornish-only origin to an inherited English mining word.
