"searched": "Read both counted-source passages and checked time range, measurement versus inference, baseline, and dating basis. Both sources agree on the approximate 4.2-Ga and >10-μT result, but the primary abstract explicitly frames it as a formation requirement and suggested dynamo inference; ETH presents it as a researcher conclusion from the combined findings."
