Abstract
Herein I propose a vision for a new multidisciplinary big science project for Canada's solid earth sciences. I call this proposed project: Taking the Pulse of Planet Earth. At a modest cost, and over a 5 to 10 year life-span, it would aim at providing the most comprehensive and multidisciplinary knowledge base of the complete record of mafic magmatism in and around Canada, and through stimulating international cooperation, around the world. A complete record of mafic magmatism (spatial distribution, ages, periodicities, rates, volume estimates, estimated geochemical fluxes to atmosphere and hydrosphere, tectonic settings, structural trends, sequence stratigraphic framework, evolving major and trace element compositions, evolving isotopic ratios, paleomagnetic information, paleo-intensities, associated ore deposits, etc.) constitutes critical input data for numerous first-order questions about the past and present evolution of our planet. Many of such questions relate to issues that are currently a focus of attention: global change, past climate extremes, complex Earth systems, planetary evolution, extinction events, flood volcanism, potential relationships with large impact events, and the discovery of new ore resources. The proposed project is a focused, smart, and highly efficient approach to solve a large number of these seemingly unrelated but first-order questions in contemporary earth science. At its core, it would have a large dating program, aiming to provide approximately 200 new, high-precision ages of mafic magmatic events across Canada and adjacent regions. A Supporting Geoscience grant system would ensure that other aspects of the magmatic record receive equal attention. Finally, I illustrate the impact this project would have on paleo-continental reconstructions. As part of this illustration, I synthesize existing data on two dyke swarms, the ca. 2.45 Ga Matachewan and Kaminak swarms, respectively, and propose a novel Superior-Hearne reconstruction within supercraton Superia. SOMMAIRE Je propose ci-contre l'idee d'un nouveau projet multidisciplinaire de grande envergure dans le domaine des sciences des roches solides au Canada. J'ai nomme ce projet « Prendre le pouls de la planete Terre ». D'un cout modeste et s'echelonnant sur cinq a dix ans, ce projet constituerait la base de connaissances multidisciplinaire la plus complete de tout le repertoire des evenements magmatiques mafiques au Canada et a son pourtour, cela, en profitant des effets stimulant de la cooperation internationale. Un repertoire complet des evenements magmatiques mafiques (distribution spatiale, âges, periodicites, taux, estimations des volumes, estimations geochimiques des flux dans l'atmosphere et l'hydrosphere, cadres tectoniques, styles structuraux, cadres stratigraphiques des sequences, compositions des suites evolutives des elements majeurs et en trace, evolution des ratios isotopiques, donnees paleomagnetiques, paleo-intensites, gisements associes, etc.) constitue un registre de donnees de base cruciales pour nombres de grandes questions sur l'evolution passee et actuelle de notre planete. Plusieurs de ces grandes questions sont liees a des problemes actuels qui mobilisent l'attention, tels : les changements a l'echelle planetaire, les evenements climatiques extremes du passe, les systemes planetaires complexes, l'evolution de la planete, les grandes extinctions biotiques, les grands epanchements volcaniques, les liens eventuels avec de grands impacts meteoritiques, ainsi que la decouverte de nouvelles sources de minerai. Le projet propose constitue une approche ciblee, « habile », et tres efficace permettant de solutionner un grand nombre de ces grands problemes, sans liens apparents, des geosciences contemporaines. Au cœur du projet on retrouve un grand programme de datation visant a etablir quelques 200 nouvelles datations de grande precision d'evenements magmatiques au Canada et dans les regions peripheriques. Un systeme de subvention d'appoint permettrait d'assurer que d'autres aspects de la problematique magmatique recoivent autant d'attention. Finalement, a titre d'illustration, je decris les repercussions escomptees d'un tel projet sur les reconstitutions paleocontinentales. Dans le cadre de cette illustration, je presente une synthese des donnees disponibles concernant deux reseaux de dykes, soit les reseaux de Matachewan et de Kaminak de 2,45 Ga, respectivement, et propose une nouvelle reconstitution Superieur-Hearne dans le super-craton Superia.

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
