Description: | The dredge consists of three large manganese nodes and variuos broken fragments. The nodules have sizes of 13x10x8 cm. 11x8x6 cm. and 9x7x6 cm. All are colored black on their outside surfaces. They appently were not buried beneath overlying sediment when dredged up because all are irregularly coated with bryozoans, worm tubes, or calcareous algae. The middle-sized nodule is broken. The broken surface of the nodule reveals its internal concretionary structure. One or more layers of manganese oxide 6-10 mm. Thick surround a nucleous of yellowish-brown, hard silty lutite. The lutite has a irregular reddish-brown coating of iron oxide, which is ijn turn coated with a black film of manganese. On all of the nodules, iron oxide has colored many of the fossil structure adhering to their surfaces. |
