Abstract
S en yesos de este ambiente, permitieron establecer que estos sulfatos fueron precipi- tados en una cuenca cerrada (sabkha continental). Palabras clave: Evaporita continental, Yeso intrasedimentario, Paleolimnologia, Provincia de Buenos Aires, Cuenca del rio Salado ABSTRACT. Intrasedimentary gypsum deposits of El Creek, Monte and General Paz districts, Buenos Aires Province. The El Creek is a tributary stream of the Salado River system, located in the north-east part of Buenos Aires province. In its lower basin, the river cuts a great depression, a remnant of an old infilled deflation basin, in which mainly aquatic sedimentary environments have operated from the Upper Pleistocene. At present, this depression represents a 2,750 ha lentic temporary environment, divided in two parts by a 2 km long, 0.7 km wide narrowing of the water basin, to the north, the minor water body named La Canada and to the south the bigger one, laguna del Siasgo. Important accumulation of intrasedimentary mainly sand- side gypsum are shown in the clastic host sediments of this palaeolentic environment The gypsum crystallized at different stratigraphic levels and with a diversity of habits, textures, fabrics and structures, The host sediment is essentially mud, but the original texture has been modified by this epigenic mineral into sandy muds, sandy silts and muddy sands. The gypsum deposit covers an area of 25,6 km 2 , with 2.15 m mean thickness in laguna del Siasgo and 0.91 m in La Canada. The total volume of gypsum sediments reaches 48 hm 3 with a minimum grade of 53,5% and 53,623,000 tons of impure gypsum , in the bigger water body, whereas in the minor one the mean grade is 20,1% which represents only 1,361,000 tons of impure gypsum. The low gypsum content in La Canada body precludes the posibilities of economic exploitation. However, the laguna del Siasgo body has high ecomonic potential, even at its lower mineral content. The genesis of these gypsums are linked to the interaction between surficial and ground waters, during the greater aridity periods of regional eolian episodes (early and middle Holocene). Isotopic determinations of δ 34 S in these gypsums indicate that the sulphates were precipitated in a closed basin (continental sabkha).

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 it
