正如署长在所述备忘录的序言中指出的那样，该地区虽然不包含许多具有经济重要性的矿床，但包括一系列非常广泛的岩石，从奥陶纪到新红岩，并希望该地区将被公认为研究所代表的地层的典型地区，如在西南威尔士开发的。
AS is pointed out by the Director in the preface to the memoir under notice, the district, though not containing many deposits of economic importance, includes a very extensive series of rocks, ranging from the Ordovician to the New Red, and the hope is expressed that the district will be recognised as a typical area for the study of the formations represented, as developed in S.W. Wales.
