Geochemistrywithout

Geochemistrywithout is a term used in some scholarly and informal discussions to describe an approach to geochemistry that emphasizes field-based data collection, open data practices, and reduced reliance on centralized laboratory infrastructure. The concept frames geochemical investigation as a collaborative, interoperable activity that can occur outside traditional lab settings, while still producing scientifically robust results.

Origin and usage of the term are diffuse. It appears in conference abstracts, workshop notes, and online platforms as a shorthand for a set of ideals rather than a single standardized methodology. As such, definitions vary among researchers, with some emphasizing practical workflows and others focusing on epistemological questions about data provenance and reproducibility.

Characteristics of geochemistrywithout typically include portable instrumentation, in-situ measurements, and the integration of diverse data streams from field observations, satellite or drone-based sensing, and citizen science. Methods may feature lightweight, field-ready protocols, open-source software for data processing, and permissive data-sharing practices that facilitate cross-disciplinary collaboration. While not intended to replace laboratory geochemistry, the approach often reduces barriers to entry and accelerates hypothesis testing through rapid iteration and transparent workflows.

Applications span environmental geochemistry, mineral exploration, groundwater studies, and planetary science analogs, where rapid, large-scale field data can inform models and decision-making. Critics caution that the absence of standardized laboratory controls can impact precision, accuracy, and comparability, underscoring the need for clear calibration, validation, and documentation. Proponents argue that when combined with rigorous validation and open data, geochemistrywithout can complement traditional methods and broaden participation in geochemical research.
