This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916. Excerpt: ... Wassalem thus shows at its type locality many of the characteristics of a reef. The outcrop of the Wassalem has a width of about two miles and south of it one finds blue and buff, very fine-grained dense limestone, somewhat purer than that at Kegel, but with the same fossils, Cyelocrinites spasskii (or C. roemeri, as Stolley calls it) being very abundant. This limestone appears to belong to the Kegel, though it has previously been called Wesenberg. The reasons for this belief are given on page 202. The Bryozoa described by Bassler as coming from the Wassalem were very probably derived from a lense of the fine-grained buff limestone associated with the reef, for their appearance and the lithology of their matrix is entirely unlike that of the typical Wassalem. (Plate 6). Wesenberg formation. E (Wesenberger schicht, partim), of Schmidt. The strata of this formation are well shown in three or four shallow quarries about one and one half miles southeast of the town from which it derives its name. The limestone is a very fine-grained, dense, blue to yellowish buff rock, so fine grained as to have received the name of "lithographic stone." It is usually in layers three to five inches in thickness, the layers separated by thin shaly partings. The good fossils adhere to the limestone and stand out in relief when the shale is washed away. The deepest quarry shows a face of sixteen feet, the lower eight feet being compact light blue limestone and the upper eight feet somewhat less compact and more magnesian limestone which becomes yellowish on weathering. Lithologically these strata differ from the rocks of the Kegel at Kegel in being less earthy, more compact, and in containing definite partings of shale. Fossils are exceedingly abundant in these quarries, the mos...
