The term Higuerueles Formation does not appear in the major geological, geographic, or scientific reference works that are publicly accessible. No peer‑reviewed publications, government geological surveys, or widely recognized encyclopedic sources identify a geologic formation by this name.
Possible Interpretation
The word “Higuerueles” resembles the Spanish “higuera” (fig tree) with a diminutive or plural suffix, suggesting a toponym that could be used for a locality or geological unit in a Spanish‑speaking region. However, without documented usage in authoritative sources, any connection to a specific stratigraphic unit remains speculative.
Conclusion
Because reliable encyclopedic information is lacking, the existence, age, lithology, geographic extent, and significance of a “Higuerueles Formation” cannot be confirmed. Further research in regional geological literature or official stratigraphic databases would be required to determine whether such a formation is formally recognized.
