Pyrite analysis from Telfer AuCu deposit 5 . INTRODUCTION . In a complex, multistage ore deposit, the preserved textures and trace element chemistry patterns in pyrite can record discrete phases of mineralising fluid.

In spite of compositional convergence between the hydrothermal zircon we describe and zircon produced by alteration of preexisting, igneous/inherited zircon grains, either during lowT seafloor alteration (Spandler et al., 2004) or due to other type of fluid circulation (Rayner et al., 2005), we also show that textural evidence in the AZMD supports hydrothermal crystallization of zircon.
The ca. Ga Morin Anorthosite Complex and its associated FeTi oxide ore deposits are loed in the Allochthonous Monocyclic Belt of the Grenville Province, Quebec. Samples from the Ivry deposit are dominated by ilmenite (8590%) and contain (in decreasing abundance) plagioclase, orthpyroxene, green spinel, clinopyroxene, Kfeldspar, amphibole, biotite, apatite, quartz, pyrite, pyrrhotite ...
· Comments: Bold: main terms for ore microscopy Italics: others than mineral names approved by IMA For stibnite the abbreviation stbn is proposed because stb is used for stilbite by Kretz (1983). Each mineral has a direct link to the mineral database Athena.. References: Chace (1956), Abbreviations in field and mine geological mapping, Economic Geology, v. 51, p. 712723.
An ore mineral The occurrence of a mineral in quantities sufficient for economic exploitation. The most important rock‐forming accessory and oxides include titanite (sphene), the spinel group, rutile, ilmenite, and zircon. Accessory phase silies are typified by small grain size, high relief,
Pyrite and chalcopyrite chemistry have revealed the physicochemical condition of oreforming fluids. • Two stages CuAu mineralization were identified in Xiaobaliang VHMS deposit. • The gold was released from the sediments whereas the copper was derived from the underlying magmatic source. •

Major ore minerals at Maoling include arsenopyrite, pyrite, galena, sphalerite, and chalcopyrite (Fig. 3j–o), and the most abundant sulfide is arsenopyrite, which comprises >75 % of the total metallic minerals. The gangue minerals include 45 % quartz and minor amounts of sericite, chlorite, and calcite. The ore structures are
As the No. 3 granodiorite has zircon twostage Hf model age (T 2DM) (1809 to 1644 Ma, Table 6) similar to the age of the basement rocks in the Shuikoushan ore field ), we consider the No. 3 granodiorite, as well as other granitoids in the Shuikoushan ore field were likely derived from partial melting of the Paleoproterozoic basement rocks that are composed mainly by metagreywackes .
Zircon is an important gemstone, with several color forms used in various forms of jewelry. Zircon is also the most significant ore of the element zirconium, and it is also the most important ore of the rare element hafnium, which can be present in considerable quantities in Zircon. In several localities, Zircon is also an ore of the radioactive element thorium.
