Abstract:

Minerals are important recorders of Earth’s evolution over billions of years. Data-driven research in mineralogy makes it easier to understand the underlying laws and driving mechanisms of the evolutionary processes of Earth. Iron plays a critical role in the matter and energy cycles, evolution of life, and environmental remediation, and is also recognized as a vitally important ‘oxygen fugacity buffer’ during the evolution of Earth surficial system. A total amount of 949 iron minerals are collected in this study. And by exploring their evolutionary patterns and distributional characteristics, a preliminary framework is constructed to tap into the intrinsic links between the evolution of deep-time iron minerals, evolution of Earth’s environment and evolution of life. The results reveal that the diversity of iron minerals has expanded episodically throughout geological history, and the peak of the growth stage coincides with the period of supercontinent collisions. The processes of plate motion, atmospheric oxygenation, and life’s metabolic activities have combined to promote the evolution of iron minerals in a more complex and diverse direction. Furthermore, back propagation neural network (BPNN), random forest (RF) and support vector regression (SVR), are used to establish and predict the evolution model of iron minerals since 4.0 Ga. The results show that RF is more appropriate to predict the evolution trend more accurately with stronger generalization ability than BPNN and SVR.
