Bulk density, ash content, humification, peat accumulation and selected lithogenic data of Store Mosse peat bog

This datafile presents chemical and physical as well as age dating information from the Store Mosse peat bog in southern Sweden. This record dates back to 8900 cal yr BP. The aim of the research was to reconstruct mineral dust deposition over time. As such we have only presented the lithogenic element data (Al, Ga, Rb, Sc, Ti, Y, Zr, Th and the REE) as the sample preparation method was tailored to these. This data is supported by parameters describing the deposit including bulk density, humification, ash content and net peat accumulation rates.

(Table, page 95) Chemistry of bog manganese concretions and wad from the Columbia County, New York

Bog manganese was long ago reported from various places in Columbia county (1:54) and it seemed well to reexamine these occurrences. According to W. W. Mather in his report of the First District Survey, 1836-42, " in the counties of Columbia and Dutchess 50,000 tons of manganese could be procured without any great expense, if carefully prepared." He also stated that some of the bog manganese showed on analysis as high as 68.5 per cent manganese oxide and less than 5 per cent silica. At the direction of the State Geologist the writer has devoted most of the summer of 191 7 to this work. The results of this investigation, though not in any way confirming the quantitative results of Mr Mather, are herewith published as a matter of record and as an account of the manner of the occurrence and the genesis of postglacial bog manganese.
