John L. Jambor made significant contributions to the field of mineralogy, influencing various subfields and research areas. Here are some of his key contributions:

1. New Mineral Discoveries: Jambor discovered or co-discovered many new mineral species, particularly supergene minerals. His work involved detailed identification and characterization of these minerals (source).

2. Research on Sulfide Mineral Oxidation: He conducted in-depth research on the geochemistry of sulfate minerals resulting from sulfide mineral oxidation, which has applications in understanding environmental impacts such as acid mine drainage (source).

3. Applied Mineralogy: His work extended to practical aspects of mineralogy, including environmental mineralogy, making notable contributions to our understanding of metallurgical processes and acid mine drainage (source).

4. Strange Lake Peralkaline Complex: Jambor's identification and characterization of economically important minerals at the Strange Lake peralkaline complex were crucial economic contributions (source).

5. Editorial and Organizational Leadership: He was integral in establishing the success of key publications like The Canadian Mineralogist, where he laid the foundation for its international acclaim (source).

John L. Jambor's work played a vital role in both academic research and practical applications in the field of mineralogy, reinforcing his reputation as a prominent figure in the scientific community.
