1)AiION Deep Learning Geothermometer – Global Subsurface Temperature Tool
AiION is a deep neural network chemical geothermometer trained on 500+ Nevada samples and validated on global datasets, using only standard major ion chemistry and pH as inputs. It explains over 97 % of variance on training and test data (R² ≈ 0.98, MAE ≈ 2.7 °C) and delivers robust subsurface temperature estimates even for blind or poorly sampled geothermal systems.
