Procland Deallrayle. By Bastini. No fossils of any kind in guachanyle, Are strata are regionally altered and their bases contact metamorphism. "Devonian granites and their associated dikes, diatreme pegmatites" There are also "fine preimes" "The sedimentary rocks of the quad. constitute a single conformable suc- cession made up of four formations 2/3 of quad. occupied by Pembrok series. Most important are the granits and the Breckpns li. Oldest sed. = Delethro Formation. Lower breccia a slate series. At Brecport Haiths, at base seen. Upper Coonnto li. Pocport Haiths. About 30 to 70 feet thick. Near it in Hog Core. The impurity is oxide as a rule, but from some areaceous matter if (maybe occuring during folding = infolding?) Thinks there once active volcanos at the time of the shale formation. "Possionally classed as Cambria" Baltic quartzite. Reticulated Baltic conglomerates. Thick 700-900 Stay contact with Delethro for conformable. Determined thickness from the lay of the crys. pebbles. Some structure, a anticlind. Bastini describes the Cryst. grown up to several feet across. Rock quartzite. To me some of the material is a crys. Pebbles all cement the same. Saw some almost black quartzite and rare a large crystalline quartzite. Says one of the pebbles are 6 wide, across, but saw at least one 12 inches long. Most are under 2 inches. Most are flat sub-rounded pebbles, but the small ones, and sometimes a large one are angular fragments. My Baltis indicate that the thickness must be considerably greater than Bastini gives it. I should say 1000 feet or more. Pembrok Formation. Thickness 700 feet or more. "Only sediments" regionally metamorphosed, and in places further altered by igneous intrusions of granite or diorite. Are "phyllites, pelite schists, amyilacean quartzites, and small amounts of true slate? Also has crys. grains with traces up to 2 feet across. Also has calcareous gones. There is complete transition from the Baltis into the Pembrok, and the Poc- port li. extremely sudden. All in one unbroken succession. Procland Formation 1 Brecley quartzite member, 200 to 300' 2 Lilecem li. member, 100 to 200' 3 Pocport li. member, the grain over, at least 400 to 500' Has "intraformational crys." once pics of 7 x 4". I should say a true Crys. Concludes it will Strockbridge and Kearney creek li. Cambrian Ordovician
