TL;DR: It is shown that Pb-rich domains previously identified in zircons from East Antarctic granulites are 5–30 nm nanospheres of metallic Pb, which are randomly distributed with respect to zircon crystallinity, and their association with a Ti- and Al-rich silica melt suggests that they represent melt inclusions generated during ultra-high temperature metamorphism.

Metallic Pb nanospheres in ultra-high temperature metamorphosed zircon from southern India
TL;DR: In this article, a transmission electron microscope (TEM) study of Paleoproterozoic zircon that has experienced ultra-high temperature (UHT) metamorphism at ca. 570 million years ago in the Kerala Khondalite Belt (KKB), southern India, documents the occurrence of metallic Pb nanospheres.
