Malmigeologian

Malmigeologian is a branch of geology that studies ore deposits, their genesis, distribution, and exploitation. It is part of economic geology and seeks to understand how ore bodies form, how to locate them, estimate their sizes, and assess their extractable resources.

Key activities in malmigeologian include field mapping, sampling, petrology and mineral chemistry, geochronology, geophysical and geochemical surveys, drilling, and resource evaluation. The discipline combines data from laboratory analysis with field observations to build models of ore systems and to guide exploration and development decisions.

Deposit types are diverse and include magmatic sulfide deposits, porphyry copper, hydrothermal veins, skarns, sediment-hosted massive sulfides and zinc-lead deposits, and laterites in some contexts. Genetic models span magmatic, hydrothermal, sedimentary, metamorphic, and supergene processes, with tectonics and fluid flow playing central roles in ore genesis.

Applications of malmigeologian include guiding mining exploration, resource assessment, and environmental and socioeconomic planning, as well as supporting sustainable extraction and reclamation strategies. The field emphasizes creating reliable resource estimates, reducing exploration risk, and integrating environmental, social, and regulatory considerations into mining projects.

Historically, malmigeologian emerged from practical mining and evolved into a formal field within economic geology, integrating field observations with laboratory analysis and modeling to support modern mining industries. Overall, malmigeologian provides critical knowledge for locating and evaluating mineral resources while addressing environmental and regulatory considerations.
