Introduction to the thematic collection: Applications of innovations in geochemical data analysis

Geochemistry: Exploration, Environment, Analysis (GEEA) as the scientific journal of the AAG focuses on the use of geochemistry in mineral exploration/resource development. Since the first issue of GEEA was published in 2001, there have been hundreds of papers regarding methodologies for geochemical data analysis. In 2017, a thematic issue: analysis of exploration geochemical data for mapping of anomalies (Carranza and Zuo, 2017) was published on the development of methods and techniques for exploration geochemical data analysis. As a successor, this current thematic set of papers introduces some new progress and advancements in geochemical data analysis, e.g., nonlinear, fractal/multifractal, multi-statistical, machine learning methods and their applications in mineral exploration. Twelve papers from Professor Qiuming Cheng's colleagues in China and Canada are organized in this thematic set in honor of his Gold Medal Award.
