The primary nugget, first reported in this paper, was discovered in No. 47 branch vein in Dakaitou ore block, Linglong gold deposit, Shandong Province. Thanks to its weight of over 29 kg, exceeding the limit weight (5 kg) of super large nugget, it is named 揝uperlarge-Linglong?nugget (Superlarge-Linglong). Observed by either naked eye or microscopy, both the Superlarge-Linglong and adjacent scattered-veinlet visible gold are composed of high-purity (903) native gold, exnclud-ing any other minerals. The Superlarge-Linglong does not cut the other types of gold ore bodies made up of high-purity micro electrum. There is, in other ore bodies and siliceous sericitolite, visi-ble gold with similar purity to it and close space-time and genetic relation to it, indicating that it is younger than other ore bodies and siliceous sericitolite. The Superlarge-Linglong and adjacent visible gold are caused by the independent nugget-visible gold metallogenetic stage.
