  <dc:description>&lt;p&gt;Ferruginous aluminous laterite beds crop out in the Ziarat-Loralai area east of Quetta for a strike length of about 60 miles. The beds are steeply dipping, sometimes overturned and faulted, and have an average thickness of 8 feet.&lt;/p&gt;&lt;p&gt;Detailed mineralogical and chemical analyses were made on chip-channel samples from four sections of the laterite in the vicinity of the village of Ziarat. One of the sections, 9 1/2 miles southeast of Ziarat, is 21 feet thick and has an average content of 42 percent available alumina, 3.6 percent silica, and 31 percent Fe&lt;sub&gt;2&lt;/sub&gt;0&lt;sub&gt;3&lt;/sub&gt;. The other sections have an average available alumina content of less than 32 percent. The alumina minerals present are mostly boehmite and diaspore, with minor amounts of kaolinite.&lt;/p&gt;&lt;p&gt;The laterite beds, which are between the Dunghan Formation of Paleocene age and the Parh Limestone of Cretaceous age, appear to mark the Cretaceous-Tertiary boundary; if this relationship is confirmed by further work, it would be of considerable assistance in prospecting for aluminous rocks in this and other parts of Pakistan.&lt;br&gt;&lt;br&gt;&lt;/p&gt;</dc:description>
