Each of these regions contains high-, moderate- and low-temperature Fe-oxide rich alteration, Cu-Au\u00c2\u00b1U mineralisation, and felsic to mafic Mesoproterozoic (~1590 Ma) intrusions of the Hiltaba Suite with or without coeval Gawler Range Volcanics. The three regions are interpreted to represent the 'footprints' of separate crustal-scale thermal anomalies. Three key hydrothermal alteration and ore mineral assemblages are recognised in the metallogenic province: (1) CAM: calcsilicate-alkali feldspar \u00c2\u00b1 magnetite \u00c2\u00b1 Fe-Cu sulfides (generally minor); (2) MB: magnetite-biotite \u00c2\u00b1 Fe-Cu sulfides, and (3) HSCC: hematite-sericite-chlorite-carbonate \u00c2\u00b1 Fe-Cu sulfides \u00c2\u00b1 U, REE minerals. Ore grade Cu-U-Au mineralisation is generally associated with the HSCC assemblage, which is paragenetically later than the CAM and MB assemblages in most deposits and prospects. The crustal level of exposure of the hydrothermal systems may vary significantly between and within the three mineralised regions. The CAM, MB and HSCC assemblages and associated Cu-Au mineralisation represent a possible spectrum of settings from deeper, higher temperature, shear-hosted environments to near-surface, low-temperature breccia and fault settings. The Olympic Cu-Au province on the eastern margin of the Gawler Craton includes three major regions of hydrothermal activity: Stuart Shelf basement (including the Olympic Dam Cu-U-Au deposit), Mount Woods Inlier and Moonta-Wallaroo-Roopena region. Each of these regions contains high-, moderate- and low-temperature Fe-oxide rich alteration, Cu-Au\u00c2\u00b1U mineralisation, and felsic to mafic Mesoproterozoic (~1590 Ma) intrusions of the Hiltaba Suite with or without Gawler Range Volcanics. The three regions may represent the 'footprints' of separate crustal-scale thermal anomalies. Hydrothermal alteration and ore mineral assemblages show systematic variations along and within the metallogenic belt. Three key assemblages are recognised: (i) CaAM: calcsilicate - alkali feldspar \u00c2\u00b1 magnetite \u00c2\u00b1 Fe-Cu sulfides (generally minor); (ii) MB: magnetite - biotite \u00c2\u00b1 Fe-Cu sulfides, and (iii) HSCC: hematite - sericite - chlorite - carbonate \u00c2\u00b1 Fe-Cu sulfides \u00c2\u00b1 U, REE minerals. Ore grade Cu-U-Au mineralisation is generally associated with the HSCC assemblage which is paragenetically later than the CaAM and MB assemblages in most deposits and prospects. The crustal level of exposure of the hydrothermal systems may vary significantly between and within the three regions of hydrothermal activity. The CaAM, MB and HSCC assemblages and associated Cu-Au mineralisation represent a possible 'continuum' of settings from deeper, higher temperature, shear-hosted environments to near-surface, low-temperature breccia and fault settings.", "num_resources": 2, "num_tags": 5, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/hydrothermal-iron-oxide-copper-gold-and-related-deposits", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[133.0, -34.0], [138.0, -34.0], [138.0, -29.0], [133.0, -29.0], [133.0, -34.0]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[133.0, -34.0], [138.0, -34.0], [138.0, -29.0], [133.0, -29.0], [133.0, -34.0]]]}", "state": "active", "temporal_coverage_from": "2018-04-22 08:47:22", "title": "Hydrothermal iron oxide copper-gold and related deposits", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "01153d18-5262-42f6-901f-4d9b0477e102"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-17T01:59:57.095919", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "View abstract for Hydrothermal iron oxide copper-gold and related deposits", "format": "HTML", "hash": "", "id": "959062e8-8e88-43ef-baa1-14f89bff059c", "last_modified": null, "metadata_modified": "2025-10-17T01:59:57.087362", "mimetype": null, "mimetype_inner": null, "name": "Related Product", "package_id": "b512600a-d2d5-4099-af01-ff2669212388", "position": 0, "resource_locator_function": "information", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "http://www.portergeo.com.au/feoxbook/feoxbook2pl.html", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-17T01:59:57.095924", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "", "format": "HTML", "hash": "", "id": "8d94d81d-48c8-418a-8327-2727d81aaa54", "last_modified": null, "metadata_modified": "2025-10-17T01:59:57.087520", "mimetype": null, "mimetype_inner": null, "name": "Unnamed resource", "package_id": "b512600a-d2d5-4099-af01-ff2669212388", "position": 1, "resource_locator_function": "", "resource_locator_protocol": "", "resource_type": null, "size": null, "state": "active", "url": "http://www.abs.gov.au/ausstats/abs@.nsf/Latestproducts/1297.0Main%20Features32008?opendocument&tabname=Summary&prodno=1297.0&issue=2008&num=&view=", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "AU-SA", "id": "8574dde3-9732-4766-8c37-5db4ee3696d9", "name": "AU-SA", "state": "active", "vocabulary_id": null}, {"display_name": "Earth Sciences", "id": "40d58e59-cdeb-4021-9e5a-aae60edebdf5", "name": "Earth Sciences", "state": "active", "vocabulary_id": null}, {"display_name": "External Publication", "id": "2ef95c3e-4342-4e16-af22-7360303a3b7b", "name": "External Publication", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}, {"display_name": "Scientific Journal Paper", "id": "5b3fac53-f275-4b8d-86c7-3bbb12947ba4", "name": "Scientific Journal Paper", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
