Magnetotelluric survey of the Kalkaroo Cu-Au Deposit, South Australia, 2020-2021 (Packed raw MTU-8A, MTU-5C, LEMI-423 time-series archive)

Brief description

This record was harvested by RDA at 2026-09-03T11:58:31.048857+10:00 from NCI's Data Catalogue where it was last modified at 2026-07-21.

Full description

This dataset contains raw broadband magnetotelluric (MT) time-series data acquired during the Kalkaroo MT survey conducted within the Curnamona Province, South Australia, during 2020 and 2021. The dataset comprises unprocessed recordings of orthogonal electric-field (Ex, Ey) and magnetic-field (Bx, By) components collected using Phoenix MTU-8A, Phoenix MTU-5C, and LEMI-423 systems. The archive includes survey deployments, remote-reference deployments, and parallel instrument comparison tests undertaken during field acquisition. Time-series data are preserved in their original acquisition formats and retain the sampling characteristics, channel configurations, and recording durations obtained during field operations. No signal processing, filtering, editing, or frequency-domain transformation has been applied beyond file collation and packaging for archival preservation. These data constitute the primary observational record of the Kalkaroo MT survey and provide the source data from which all subsequent processed and derived MT products are generated.

Lineage

This dataset contains raw broadband magnetotelluric (MT) time-series data derived directly from field acquisition activities undertaken during the Kalkaroo MT survey conducted within the Curnamona Province, South Australia, during 2020 and 2021. Data are preserved in the original native acquisition formats generated by Phoenix MTU-8A, Phoenix MTU-5C, and LEMI-423 systems and represent unprocessed field measurements collected during survey deployments, remote-reference deployments, and instrument comparison tests. The dataset includes deployment metadata recorded during field operations, including station identifiers, geographic coordinates, deployment and recovery dates, instrument information, and associated field observations where available. The dataset has not undergone signal processing, filtering, resampling, calibration, or transformation beyond file collation and packaging for archival preservation. Persistent identifiers and associated hardware provenance records for individual instruments are maintained separately and may be used to resolve instrument-specific deployment information and equipment provenance. This dataset constitutes the authoritative raw time-series archive of field-acquired observations from the Kalkaroo MT survey and forms the basis for all subsequent processed, interpreted, and derived data products.
