Tasmanian Plutonic Rock Zircon Ages from SHRIMP Analysis, 2012-2013

Six new zircon U-Pb geochronological data points obtained via Sensitive High-Resolution Ion Micro Probe (SHRIMP) from plutonic igneous rocks in Tasmania. The data were collected between July 2012 and June 2013 by the collaborative Geochronology Project between Mineral Resources Tasmania and Geoscience Australia. Five samples are from the Eastern Tasmanian Terrane and one from the Western Tasmanian Terrane.

Use Cases

• Refining regional chronology of mid-Palaeozoic felsic magmatism based on new SHRIMP U-Pb zircon ages.
• Correlating geological units between the Eastern and Western Tasmania Terranes based on sample provenance.
• Supporting economic geology assessments for samples chosen due to their stated economic importance.

Strengths

• Data originates from a collaborative project between two government geological organizations, Mineral Resources Tasmania and Geoscience Australia.
• Samples have specific provenance, with five from the Eastern Tasmanian Terrane and one from the Western Tasmanian Terrane.
• The study builds upon a prior extensive U-Pb SHRIMP zircon study (Black et al., 2005), providing temporal context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small, containing data from only six rock samples.
