  <dc:description>&lt;p&gt;&lt;span&gt;The orthorhombic crystal structures of shattuckite, Cu&lt;/span&gt;&lt;sub&gt;5&lt;/sub&gt;&lt;span&gt;( SiO&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;)&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;(OH)&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;and planch&amp;eacute;tite, Cu&lt;/span&gt;&lt;sub&gt;8&lt;/sub&gt;&lt;span&gt;(Si&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;0&lt;/span&gt;&lt;sub&gt;11&lt;/sub&gt;&lt;span&gt;)&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;(OH)&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;H&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O, have been solved. Shattuckite contains silicate chains similar to pyroxene in a complex association with copper atoms, while the closely related planch&amp;eacute;ite contains silicate chains similar to amphibole.&lt;/span&gt;&lt;/p&gt;</dc:description>
