{"id":"https://openalex.org/G449348664","display_name":"Petrologic Characteristics of Tectonic Blocks and Associated Rocks in the Yuli Belt, Eastern Taiwan (Iii)","description":"The Tananao Complex in the eastern Taiwan represents the pre-Tertiary(?) \u201cbasement\u201d of this island. Based on lithology, the Complex is subdivided into the Tailuko belt in the NW and the Yuli belt in the SE. Despite several decades of study, quantitative P-T paths for this complex remain unresolved, mostly due to lack of index minerals or suitable mineral assemblages for thermobarometry. In particular, the Yuli belt contains rare high-pressure metamorphic rocks and bears important implications for the geodynamic evolution of Taiwan. This project aims to study the field occurrence, petrography, petrogenesis, mineral/rock chemistry, equilibrium physical conditions, and P-T evolution of metamorphic rocks in the \u201ctectonic\u201d (\u201cexotic\u201d) blocks and adjacent rocks in the Yuli belt. The Juisui, Wanjung, and Chinshuichi areas are the main targets. The Juisui tectonic block is dominated by mafic rocks, which are different from the in-situ semi-pelitic or -psammitic schists of the Yuli belt. Although chemically the tectonic blocks are exotic in nature, whether the mafic rocks within the blocks had been through the same (coherent) regional metamorphism with the surrounding in-situ schists remains unknown. A previous study showed a clockwise P-T path for the tectonic blocks of Juisui and Wanjung (Beyssac et al., 2008). However, the petrographic information and P-T constraints provided by that study revealed some flaws and their concluded P-T path appears to be contrary to those of some classic studies by Liou (1981) and Liou et al. (1975). Our recent work have shown that rocks from the Juisui block bear diverse nature in mineral compositions and P-T evolution (Tsai et al., 2013). A revision on the tectonic blocks and the extent of the high-pressure/low-temperature (blueschist-facies) metamorphism of the Yuli belt is needed urgently. We aim to systematically investigate the rocks from the tectonic blocks and nearby area with petrologic and petrographic characterization. The rocks of research interest will include glaucophane-bearing rocks, garnet-bearing metabasites, garnet-bearing semi-pelitic schists, albite schists, chlorite schists, and meta-psammites. Results from this project will provide key information for ongoing or further geochronologic work to better understand the tectonic evolution of the Taiwan basement sequence.","funder_award_id":"MOST103-2116-M259-003","funder":{"id":"https://openalex.org/F4320322795","display_name":"Ministry of Science and Technology, Taiwan","doi":"https://doi.org/10.13039/501100004663"},"funded_outputs":["https://openalex.org/W1769327064"],"funded_outputs_count":1,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":1431000.0,"currency":"TWD","amount_usd":47228.97,"amount_usd_basis":"annual_average","recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"\u5b78\u8853\u88dc\u52a9","start_date":null,"end_date":null,"start_year":2014,"end_year":2015,"landing_page_url":"https://www.grb.gov.tw/search/planDetail?id=8312332","doi":null,"provenance":"grb_most_projects","lead_investigator":{"given_name":null,"family_name":"\u8521\u91d1\u6cb3","orcid":null,"role_start":null,"affiliation":{"name":"\u570b\u7acb\u6771\u83ef\u5927\u5b78\u81ea\u7136\u8cc7\u6e90\u8207\u74b0\u5883\u5b78\u7cfb","country":null,"ids":null},"author":null,"institutions":[{"id":"https://openalex.org/I33096239","display_name":"National Dong Hwa University","ror":"https://ror.org/00mng9617","country_code":"TW","type":"education","lineage":["https://openalex.org/I33096239"]}]},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G449348664","primary_topic":{"id":"https://openalex.org/T10001","display_name":"Geological and Geochemical Analysis","score":0.9995,"subfield":{"id":"https://openalex.org/subfields/1906","display_name":"Geochemistry and Petrology"},"field":{"id":"https://openalex.org/fields/19","display_name":"Earth and Planetary Sciences"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},"topics":[{"id":"https://openalex.org/T10001","display_name":"Geological and Geochemical Analysis","score":0.9995,"subfield":{"id":"https://openalex.org/subfields/1906","display_name":"Geochemistry and Petrology"},"field":{"id":"https://openalex.org/fields/19","display_name":"Earth and Planetary Sciences"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},{"id":"https://openalex.org/T11740","display_name":"Geochemistry and Elemental Analysis","score":0.0001,"subfield":{"id":"https://openalex.org/subfields/1906","display_name":"Geochemistry and Petrology"},"field":{"id":"https://openalex.org/fields/19","display_name":"Earth and Planetary Sciences"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},{"id":"https://openalex.org/T13442","display_name":"Geochemistry and Geochronology of Asian Mineral Deposits","score":0.0,"subfield":{"id":"https://openalex.org/subfields/1906","display_name":"Geochemistry and Petrology"},"field":{"id":"https://openalex.org/fields/19","display_name":"Earth and Planetary Sciences"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}}],"keywords":[{"id":"https://openalex.org/keywords/tectonic-blocks","display_name":"tectonic blocks","score":0.9},{"id":"https://openalex.org/keywords/pressure-temperature-paths","display_name":"P-T path","score":0.689},{"id":"https://openalex.org/keywords/blueschist-metamorphism","display_name":"blueschist metamorphism","score":0.812},{"id":"https://openalex.org/keywords/high-pressure-metamorphism","display_name":"high-pressure metamorphism","score":0.856},{"id":"https://openalex.org/keywords/glaucophane","display_name":"glaucophane","score":0.732},{"id":"https://openalex.org/keywords/chlorite-schist","display_name":"chlorite schist","score":0.973},{"id":"https://openalex.org/keywords/petrogenesis","display_name":"petrogenesis","score":0.722},{"id":"https://openalex.org/keywords/petrography","display_name":"petrography","score":0.689}],"sustainable_development_goals":[],"institution_awarded":[{"id":"https://openalex.org/I33096239","display_name":"National Dong Hwa University","ror":"https://ror.org/00mng9617","country_code":"TW","type":"education","lineage":["https://openalex.org/I33096239"]}],"updated_date":"2026-11-13T03:01:57.000Z","created_date":"2026-07-13T04:25:35.000Z"}
