Geological History of Lava flows and Graben Systems (Dyke Swarms) Of The Mbokomu Mons Region, Along Parga Chasmata, 2400 Km SE Of Atla Regio, Venus.
Bibliographic record
Abstract
Introduction: The relationship between coronae and chasmata has been extensively discussed but is still enigmatic (e.g. [1-6]). One such relevant region is along the 10,000 km long Parga Chasmata which connects Atla Regio with Themis Regio. On the basis of detailed mapping of graben fissure systems and interpreted rift faults along a 1500 km long segment of Parga Chasmata, [6] recognized that many coronae represent the locus of local triple junction rift centres; extrapolating this observation to the entire length of Parga Chasmata (and also Hecate Chasmata), and then compared it to the Atlantic rift system of Earth. To explore these relations more fully, we have selected a region along Parga Chasmata for detailed study. The general area is about 2000 km SE of the centre of Atla Regio and we focus on Mbokomu Mons. The goal of the present research is to provide detailed mapping (1:500,000 scale) of the graben fissure systems, lava flows associated with Mbokomu Mons (and in the surrounding area), in order to provide insights into the setting of coronae within the broad Parga Chasmata rift system. Our mapping builds on the previous reconnaissance mapping (1:5,000,000 scale) of Taussig Quadrangle (V–39) [7]. Initial mapping of the graben associated with Mbokomu Mons are provisionally grouped into distinct sets, which we provisionally interpret to mainly represent dyke swarms of both radiating, circumferential and linear geometry, on the basis of previously established criteria [e.g. 8,9]. We are attempting to identify potential magmatic centres as sources for these swarms. Flow systems to the east, and north and west of Mbokomu Mons are visible and mapped. Topographic profiles are provide for Mbokomu Mons. Upon completion, this detailed mapping will provide significant insight into the relationship between chasmata and associated coronae, of relevance to chasmata across Venus.

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.
