Saholan Cave formed through dissolution of limestone bedrock by acidic groundwater, a process that has been ongoing for hundreds of thousands to millions of years. The cave system developed along fractures and bedding planes in carbonate rocks deposited in ancient marine environments. Speleothem formations within the cave grew through calcium carbonate precipitation, creating the stalactites, stalagmites, and other features visible today. These formations record environmental conditions during their growth, providing valuable paleoclimate information. The cave's morphology reflects both the geological structure of the host rock and the evolution of underground water flow patterns. Different cave passages represent various stages of development, with some actively forming and others relict features from past hydrological conditions. The surrounding geology includes folded and faulted rock layers characteristic of the tectonically active Zagros region. Study of Saholan Cave contributes to understanding karst processes, regional geological history, and long-term environmental change in northwestern Iran.

The climate outside Saholan Cave reflects the mountainous conditions of West Azerbaijan Province, with cold winters and mild to warm summers moderated by elevation. The region receives significant precipitation, particularly during winter and spring, supporting the groundwater recharge necessary for karst processes. Snow cover is common during winter months, with snowmelt contributing to seasonal fluctuations in underground water flow. Inside the cave, temperature and humidity remain relatively stable year-round, buffered from surface weather variations by the insulating effect of overlying rock. Cave interior temperatures typically reflect the average annual surface temperature, creating consistently cool conditions. High relative humidity within the cave supports speleothem growth and influences cave ecology. Surface climate variability affects cave processes through changes in water input, carbon dioxide levels, and temperature at the cave entrance. Long-term climate records preserved in speleothems provide insights into past climate variations in the region. Current climate trends may influence cave dynamics, though the subsurface environment responds slowly to surface changes.
