Display Field: Garnet_ID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: <p>The Himalayan Garnet Analysis Database (HGAD v1.0) contains 12,434 garnet compositional analyses from 796 unique localities across the Himalaya and adjacent regions. This layer shows HGAD source localities used for geochemical visualization, comparison, and provenance analysis.</p>

Copyright Text: The full HGAD platform is available at tinyurl.com/HimalayanGarnetDB, and the foundational compiled dataset can be found at Catlos, Elizabeth. 2026. Replication Data for: Himalayan Garnet Analysis Database, Version 1.0. Texas Data Repository. https://doi.org/10.18738/T8/GZLMUW. CC0 1.0. Citation information will be updated following publication of the associated manuscript. The dataset integrates standard electron microprobe (EPMA) garnet data published in tables or supplementary files in 167 peer-reviewed papers, six theses (Catlos, 2000; Chambers, 2008; From, 2012; Prince, 2000; Saha, 2020; Stahr, 2013), and one database (Chiama et al., 2022). HGAD is not intended to be a comprehensive dataset of all Himalayan garnet compositions, but rather to provide a robust, representative dataset suitable for evaluating trends and for comparing compositions with those available from the Siwalik Group.
