XRD-XRF application plus

MinID-X: XRD & XRF Mobile Application - Brief Description
🎯 Overview
MinID-X is a specialized Android application for offline mineral identification using X-ray Diffraction (XRD) and X-ray Fluorescence (XRF) data. Designed for field geologists, researchers, and students working in remote or resource-limited environments.
🔬 Core Functionality
XRD Module (X-ray Diffraction)
✅ Hanawalt-style search: Match measured d-spacings (±0.02 Å tolerance) against compressed COD database (~196 MB, 37,727 minerals)
✅ Peak input: Enter up to 20 strongest diffraction peaks manually or via file import
✅ Instant results: Ranked mineral candidates with crystal system, formula, and space group
✅ Offline operation: No internet required—critical for fieldwork in Algeria's Sahara and other remote regions
XRF Module (X-ray Fluorescence)
✅ Elemental reference: Quick lookup of elements (Z=1–103) with atomic properties and common mineral hosts
✅ Composition cross-check: Validate XRD identifications against detected elemental composition
✅ Educational tool: Learn elemental associations in mineral groups (e.g., sulfides, carbonates, silicates)
