Petrography and Petrogenesis of the Neshveh Intrusive Rocks, Northeast Saveh, Central Iran
Bibliographic record
Abstract
The Neshveh intrusive mass is located in the Northeast of Saveh and is considered as a part of the Urumieh-Dokhtar magmatic arc (UDMC). The mass is replaced in the Eocene-Oligocene volcanosedimentary rocks consist mainly of quartz monzodiorite, granodiorite and granite. Based on the Field studies, petrographical and geochemical evidences, the Neshveh rocks have derived from a K-rich, metaluminous calc-alkline magma. P2O5 versus SiO2 has a decreasing trend that is a sign of I-type rocks. Due to entrance into the structure of minerals like: Fe-Ti oxides, plagioclase and hornblende, MgO, Fe2O3, MnO, Al2O3 and TiO2decrease with increasing SiO2. On the other hand Rb and Ba increasing trend demonstrate no fractionation of biotite and K-feldspar during the magma evolution. Y decreasing trend results from fractionation of hornblende. REE patterns of the studied rocks normalized by Chondrite, follow same trend representing their unity source and the role of the fractionation in the magma evolution. Low amounts of some elements such as; V, Co, Cr, Ni, Mg# in Neshveh intrusive rocks reveal their formation from an evolved magma.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
