However, some saints are associated with the Earth and natural sciences, and could be considered honorary patrons:

* Saint Barbara: Traditionally, she's associated with miners and those who work with explosives.

* Saint Catherine of Alexandria: She is often depicted with a wheel, which could be linked to the cyclical nature of geological processes.

* Saint Michael the Archangel: He is associated with the protection of people and places, which could be interpreted as protecting those who explore and study the Earth.

Ultimately, the choice of a patron saint is personal. Any saint who embodies the values of curiosity, exploration, and respect for the natural world could be considered a fitting patron for geologists.
