(b) Puckered Argillaceous Sandstone, from loDg cross-cut in North Mount Boppy .Mine. 19 The Girilambone Series described below probably belongs to the same greatgroup as the Canbelego sediments. Detailed descriptions.—The relative positions of the Canbelego Series are indicated on the general maps and sections. CJaystones.—On the surface these vary from reddish, pink, grey, yellowish,to whitish in colour. They have a strong development east of the townshipof Canbelego, as also west of the same locality. The usual method of occur-rence is as thin beds alternating with laminated sandstones. The wholeseries is usually contorted and minutely puckered. Plate VII (&) is a detailof a common association of claystone and sandstone. In fresh fractures thedetails of structure are difficult to make out, but on weathered surfaces, asin the railway cuttings of recent formation the details of structure may bemade out easily. Some of the types are well-bedded. Analysis of ironstai
