August 12 Continued.
Clarke in the 18th Rep. of the Directors of the State Mus. 1924 says this: "The critical region for the precise determination of the stratigraphy of the Basque sandstone, and the incoming stages of the Bonaventure formation, is the extremity of the St. Peter peninsula" (125). The Upper Basque sandstone in the St. Peter region "is gradually replaced by the Bonaventure sediment" (125). South and east of the faults near Chim Blance the green-pig Basque sandstone are followed by "at least four beds of conglomerate separated by by broad intervals of red to brown shales, the first of these, of lighter shale than the rest carrying plant remains of the same character as those in the Basque sandstone. The entire series on this north shore is terminated at St Peter point by a very heavy bed of conglomerate which is continued out ward to Plats island" (129). Clarke caps me and concludes that these congls. are all of the Bonaventure being the transition to the true Bonaventures.
To me all of those congls. are but beds in the Basque ss and that they have nothing at all to do with the Bonaventures.
The "Bonaventures" to the N. of Grand Crique shore and that under the Richmond area are not Bonaventures, but some part of the Basque ss. The B. j. St. Anne and the Pic is true Bonaventure and so would that of Bonaventure Island. The "Bonaventures" on the top of the Beaumenne cliffs is also not true B, but a part of the Basque series. In other words the Basque ss becomes more and more congls. and red towards the top of the series.
