The problem of the age of radioactive mineralization in the singhbhum shear zone, india
Ramifications of Extreme Age of St. Peter and St. Paul Rocks
This note summarizes the research followed for nearly 15 years on the Quaternary of the Northwest Sahara. Stratigraphically it is possible to characterize the Villafranchian, with two pluvial-arid cycles (Aïdien and Mazzérien) ; the middle Quaternary, with two cycles (Taourirtien and Ougartien); and the late Quaternary, with a main cycle (Saourien) followed by a secondary cycle (Guirien). The sedimentary petrography has shown climatic indications in successive deposits (granulometry of pebbles and sands, various marks on pebbles, colorimetry of sands) and some chronological and paleogeographical indications (heavy minerals). Palynological studies in progress reveal the presence, at different times of the Quaternary, of Mediterranean and even temperate trees, associated with herbs of the Saharian steppe. The collections of all the Saharan prehistoric industries, in place in all Quaternary levels, is a useful element in dating. The Pebble Culture appears in the Mazzerien and the beginning of the Taourirtien. The Chelleen and the Acheuleen develop during the Taourirtien, and the Ougartien appears in a series of stages stratigraphically well defined. Aterien is present toward the base of the sourien deposits, and the Neolithic occurs in the Guirien. A radiocarbon analysis of 20,000 ± 1000 years B.P. dates a saourien level near the Aterien, and one of 6160 ± 320 dates the maximum of the Guirien sedimentation, of Neolithic age.
Quaternary Geology, Radiocarbon Datings, and the Age of Australites
By means of archaeological methods of excavation, in which sand was removed inch by inch, 14 australite specimens were discovered in situ, along with materials for radiocarbon dating. A study was made of the history of materials forming the humus podsol in which the australites occur. The glass of australites found in situ is dulled, but the structures are sharp, showing that little movement has occurred. No australite has been found in or below the hardpan of the humus podsol. Seven radiocarbon datings were made of fossil hardpan material, of charcoal at various levels above the hardpan, and of grass tree resin in situ above the hardpan. The oldest date was 7300 years for carbonized wood fragments in the hardpan. By its physiographic and stratigraphic relationships, and by its analogy with similar soils elsewhere in Victoria, the humus podsol is believed to have formed during the last glacial period. The possibility of an age for australites younger than the one some chemists and physicists have proposed therefore should be seriously considered.
