The Exhalative-sedimentary Evidence of the Bainiuchang Ag-polymetallic Deposit,Yunnan,China:Constraints from Geochemistry of Host-rocks
Bibliographic record
Abstract
Studying if there took place extensive exhalative-sedimentary activities in the southeast Yunnan Province has been one of key factors to constrain origin of the Gejiu,Bainiuchang,and Dulong polymetallic deposits.The authors systematically study the geochemistry characteristics of host-rocks in the Bainiuchang Ag-polymetallic deposit in this paper.The host-rocks have the same distribution area with the sea-floor volcano or hot-water origin chert.Then normalized REE distribution patterns of host-rocks can be divided into two groups: One group with higher total REE contents indicates more normal sediments attendance.The other group with lower total REE contents possesses the similar normalized REE distribution patterns and parameters with rich-tourmaline banded hydrothermal sediments in the Canada Sullivan deposit and banded chert in iron-bearing formations in the Canada Agnico-Eugle deposit.And the pairs of trace elements show the similar characteristics with modern sea-floor hydrothermal sediments.In addition,the contents of As,Sb and Ag are similar with that of chert in the Dachang and the Gejiu mining districts.Based on above of all,it is indicated that the Bainiuchang Ag-polymetallic deposit is exhalative-sedimentary origin.

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.
