LithoLab provides free, browser-based geological calculation tools for students, researchers, and field geologists β from grain-size classification to geochemical weathering indices and planetary crater scaling.
Nine free, in-browser calculators covering sedimentology, geochemistry, hydrogeology, stratigraphy, and planetary science. No login. No download. Just science.
Classify sediment by Wentworth Scale. Input mm, ΞΌm, or Ξ¦ units. Returns depositional environment interpretation.
βChemical Index of Alteration from major oxide inputs. Quantifies intensity of silicate weathering.
βCompute CIA, PIA, CIW, ICV, and WIP simultaneously from a single oxide dataset.
βSolve for flow rate Q, hydraulic conductivity K, or gradient i from the classic groundwater equation.
βCalculate porosity from density or volume measurements. Optional Kozeny-Carman permeability estimate.
βBidirectional conversion between millimetres and the phi (Ξ¦) scale. Includes Wentworth reference table.
βBulk density from mass/volume or from mineral volume fractions. Returns rock-type inference.
βInteractive reference for the International Chronostratigraphic Chart β filterable by eon and searchable by period.
βEstimate final crater diameter using Pi-scaling relations (Schmidt & Housen 1987). Supports Earth, Mars, Moon, Venus.
βPeer-reviewed publications indexed on ScienceDirect (2025), contributed through geospatial figure preparation and graphical data visualisation.
