The Hf-W chronology of Nedagolla indicates that this mixed NC-CC isotopic composition was established relatively late, more than 7 million years after Solar System formation. The mixed NC-CC isotopic composition is consistent with the chemical composition of Nedagolla, which combines signatures of metal segregation under more oxidizing conditions (relative depletions in Mo and W)","authors_text":"Christoph Burkhardt, Fridolin Spitzer, Jonas Pape, Thorsten Kleine","cross_cats":["physics.geo-ph"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"astro-ph.EP","submitted_at":"2021-09-09T12:40:44Z","title":"Collisional mixing between inner and outer solar system planetesimals inferred from the Nedagolla iron meteorite"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2109.04224","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:64d613644007592d35f71cd270ea34e8554ea0c8d592bcf500b139690650c6bb","target":"record","created_at":"2026-07-05T03:58:53Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"258aa35c028c4b2020c5cd3343da19f6ccfb8bcf152bc97aee9dd809cc802259","cross_cats_sorted":["physics.geo-ph"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"astro-ph.EP","submitted_at":"2021-09-09T12:40:44Z","title_canon_sha256":"ad5595dbcb53574ff692b7bfeb49562f2da1ecb55cb700784f1bfa74a20c8679"},"schema_version":"1.0","source":{"id":"2109.04224","kind":"arxiv","version":1}},"canonical_sha256":"8c13f132969062e0905c050de023b2ff3b8acfe3c342eab1a5970c162a8b6093","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8c13f132969062e0905c050de023b2ff3b8acfe3c342eab1a5970c162a8b6093","first_computed_at":"2026-07-05T03:58:53.557476Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:58:53.557476Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"COQi2AEjhtKxHmps7E6kqdf98oly3M94HdjHFeLB3q6RM7EqLxtfzq0tpU7T4/ZZqI9jaV2ogpPxt6IvMeA5AA==","signature_status":"signed_v1","signed_at":"2026-07-05T03:58:53.557946Z","signed_message":"canonical_sha256_bytes"},"source_id":"2109.04224","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:64d613644007592d35f71cd270ea34e8554ea0c8d592bcf500b139690650c6bb","sha256:78384677691a2fc01693907215bbe4c31ab71f3745b50e8c0167f63def99005c"],"state_sha256":"bbcb9b25f58e77a24f6b50346b685b5d8dabe8dfeb8bf3ec2c74b777853fad3a"}
