ARC Research Hub for Australian Copper-Uranium director Stephen Grano said: "Much of South Australia's copper deposits are actually very fine intergrowths
of a range of different metals and minerals.
Although the final aim of this research is working with real mineral particles, first attempts of texture characterization have been carried out on a series of textures in synthetic biphasic particles that represent the intergrowths
described by Gaudin (1939) in a simple way (Fig.
Galena formed irregular intergrowths
with sphalerite and was abundant in a few thin layers in zinc and copper-zinc ore (Payne et al.
Perthitic and myrmekitic intergrowths
are observed in few sections.
Granophyric (more wormy) to graphic (more cuneiform) intergrowths
between feldspar and quartz are evident in three samples (DDH 79-6-174.
3] ceramics has demonstrated that what actually forms is not a solid solution but rather a homologous series of distinct compounds which feature intergrowths
The RP-type Cobaltites: Intergrowths
of Perovskite and Rock Salt Layers and Derivatives
The character of the sulphide intergrowths
varied considerably in different parts of the orebody, even within individual stopes, and variations of several percent in zinc, lead and iron content of the mill feed were common.
It canbe observed the following mineralogical assemblage: quartz--alkali feldspar intergrowths
(micrographic/granophyric texture) and partially altered clinopyroxene (augite) often exhibiting uralitization processes.
of quartz and K-feldspar are common in the granite associated with comb quartz layers, both of which reflect a significantly undercooled magma (Fenn 1986; Lentz and Fowler 1992).
Roth, Defect Intergrowths

It is therefore significant that new U--Th disequilibrium data for gypsum-atacamite intergrowths
from several deposits in northern Chile indicate formation ages of ~240 ka to as young as ~80 ka (Reich et al.
