Geophysical Interpretation of the Braidwood Granodiorite on the Braidwood 1:100 000 Sheet
Bibliographic record
Abstract
AbstractInterpretation based on the Total Magnetic Intensity (TMI), gravity, radiometric and digital elevation data acquired as a part of the Exploration NSW initiative, focused on the northern part of the Braidwood Granodiorite and its extension to the north of the Shoalhaven River. The use of image processing Sobel filters on the TMI gridded data enhance characteristics such as faults and regional stress fields that would otherwise be very difficult to observe.Compared to other granites, the Braidwood Granodiorite is unusually magnetic. Palaeomagnetic studies are being conducted along with petrographic work to determine whether the magnetite in the granite is a primary magmatic mineral or the result of secondary alteration.The Dargues Reef gold deposit lies within the southern part of the Braidwood Granodiorite. It is a member of the intrusion-related gold deposit class that includes Timbarra in NSW and Kidston and Red Dome in Queensland. These four deposits are associated with potassic, oxidised I-type granites that contrast with other overseas intrusion-related gold examples (e.g. Alaska-Yukon), which are reduced and non-magnetic.Technical Area: Geophysics in Government Surveys

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
