Structure Types<br />
We will talk about the remaining crystal structures (especially for silicates!!)<br />
as we talk about the various mineral groups.<br />
Remember: isostructural groups may have “substitution” of cations from other<br />
members of the group into the cation structure sites. This is a type of:<br />
<strong>Solid</strong> Solution: a mineral structure in which specific atomic<br />
sites are occupied in variable proportions by two or more<br />
different chemical elements (or vacancies)<br />
There are 3 different types of solid solution, the most important of which is<br />
called “substitutional<br />
solid solution’
