Haldford Strata

Haldford Strata functions as a geological diagnostic utility. It indexes twenty-one common minerals, rock groups, and ores. The system operates without network permissions or account dependencies. The directory allows filtering by group, name, or hue. Specimen profiles detail luster, streak, color, and Mohs hardness, alongside diagnostic criteria and environmental context. A sequential filtering key aids identification. The tool evaluates metallic surface properties, scratch resistance against standard materials like glass or a knife, and streak hue on unglazed ceramic. Parameters can be bypassed to retain broader candidate matches. A Mohs scale module specifies ten hardness levels mapped to physical tests. A self-evaluation mode obscures and shuffles this sequence, verifying knowledge upon screen interaction. A localized archiving tool logs collected specimens, geographic origins, and text annotations. All input is stored exclusively on device memory and sorted chronologically in Haldford Strata.
