Zirconium and Hafnium Statistics and Information
The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
Continental growth histories revealed by detrital zircon ...
Zircon saturation is elevated in silicic melts, which are often generated along continental arcs (Lee and Bachmann, 2014). The detrital zircon record is therefore strongly influenced by regional arc magmatism ( Lee et al., 2016 ; McKenzie et al., 2016 ), an important mechanism for crustal addition via water-induced melting of the upper mantle ...

In this context, the main advantage of our approach compared to an analytical equivalent is merely the ability to specify numerically an arbitrary f(t r) derived from a physics-based model.

Detrital Zircon from the Jack Hills and Mount Narryer ...
Abstract Geochronological, geochemical, and morphological analysis of detrital zircon in the Jack Hills and Mount Narryer metasedimentary belts, Western Australia, indicates the grains were derived from diverse rocks, including >4000 Ma sources that predate the oldest known terrestrial rock. In three metaconglomerate layers in the western part of the Jack Hills, 4200–3800 Ma zircon makes up ...

Zircon U–Pb analyses yield ages of 450 ± 1 Ma and 445 ± 2 Ma for the granite porphyry, indicating that it formed during Late Ordovician time. The granite porphyry is metaluminous to slightly peraluminous (aluminous saturation index A/CNK = 0.98–1.11) with high SiO 2, K 2 O and Na 2 O concentrations and differentiation index (DI = 85–90).
Publications Review | Zircon Industry Association
The Zircon Industry Association annually identifies the most popular areas of research relating to zircon and its downstream derivatives. Following a review of over 2,600 peer-reviewed papers published in 2019, it has been possible to identify these areas of research and make an informed assumption as to the likely potential for industrial application.
Detrital zircon geochronology - Wikipedia
Detrital zircon geochronology is the science of analyzing the age of zircons deposited within a specific sedimentary unit by examining their inherent radioisotopes, most commonly the uranium–lead ratio.The chemical name of zircon is zirconium silicate and its corresponding chemical formula is Zr SiO 4.Zircon is a common accessory or trace mineral constituent of most granite and felsic ...

A review of continental growth models leaves open the possibilities that Earth during the Hadean Eon (∼4.5–4.0 Ga) was characterized by massive early crust or essentially none at all. Without support from the rock record, our understanding of pre-Archean continental crust must largely come from investigating Hadean detrital zircons. We know that these ancient zircons yield relatively low ...

Hadean zircon - Wikipedia
Hadean zircon is the oldest-surviving crustal material from the Earth's earliest geological time period, the Hadean eon, about 4 billion years ago. Zircon is a mineral that is commonly used for radiometric dating because it is highly resistant to chemical changes and appears in the form of small crystals or grains in most igneous and metamorphic host rocks.
