The area is mainly underlain by high-grade metamorphic units and intrusive rocks. Gold-sulphide bearing quartz veins are predominantly hosted in gneisses and marbles. Numerous faults striking N, NNE, ENE and E to ESE with moderate to steep dips occurred in the area. The veins are characterized by banded, colloform, cockcade, breccia and some vuggy textures. The vein-related alteration is characterized by silicification, sericitization and chloritization from\r the inner to the outer zones. Principal metallic minerals are pyrite, chalcopyrite, sphalerite, galena, arsenopyrite in addition to electrum. The mineralogy of the vein is recognized into three paragenetic stages. Stage 1 is pre-mineralization stage. Stage 2 is main mineralization stage and stage 3 is post-ore carbonate stage. Quartz with minor sulfide, mainly pyrite was deposited during stage 1. Precious and base metals were precipitated during stage 2. In this stage, adularia is common. Gold and silver are more enriched in the veins containing abundant adularia than virtually quartz rich veins. In stage 3, the veins are barren. Bullion\r fineness data of the whole area display a wide range of fineness (416-875). Garnet and wollastonite minerals are found in the west of Chaunggyi, Kabani and Bwettaw indicating that skarn assemblages formed in the area. In comparison, the eastern part of the system displays an epithermal character as evidenced by the mineral texture and the presence of adularia. Metamorphic\r belts such as MMB are complex tectonic regions in which diverse types of gold deposit can be formed. Therefore, the mineralization of the Kwinthonze-Nweyon area can be consisted of epithermal to mesothermal (orogenic) and skarn mineralization genetically linked with calc-alkaline, peraluminous magmatism."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Mogok Metamorphic Belt (MMB)"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Precious and Base Metal Mineralization in Kwinthonze-Nweyon area, Singu and Thabeikkyin Townships, Mandalay Region, Myanmar.pdf", "filesize": [{"value": "2978 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2978000.0, "url": {"url": "https://meral.edu.mm/record/781/files/Precious and Base Metal Mineralization in Kwinthonze-Nweyon area, Singu and Thabeikkyin Townships, Mandalay Region, Myanmar.pdf"}, "version_id": "362da9f3-97f8-437d-a10c-5fdf868d5f5f"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Proceedings of Su ndanald Resources 2014 Megi Annual Convention Masyarakat Geologi Ekonomi Indonesia (Indonesian Society of Economic Geologists)"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Tin Aung Myint"}, {"subitem_authors_fullname": "Than Than Nu"}, {"subitem_authors_fullname": "Min Aung"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Conference paper"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2014"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://umoar.mu.edu.mm/handle/123456789/440"}, "item_title": "Precious and Base Metal Mineralization in Kwinthonze-Nweyon area, Singu and Thabeikkyin Townships, Mandalay Region, Myanmar", "item_type_id": "21", "owner": "1", "path": ["1582967109396"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000781", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "781", "relation": {}, "relation_version_is_last": true, "title": ["Precious and Base Metal Mineralization in Kwinthonze-Nweyon area, Singu and Thabeikkyin Townships, Mandalay Region, Myanmar"], "weko_shared_id": -1}
