Paleomagnetism of the Upper Vendian Basu formation of the Bashkirian Meganticlinorium revisited

We have carried out paleomagnetic studies of the Upper Vendian sedimentary rocks from the Bashkirian Meganticlinorium (Southern Ural). The rocks were sampled at three localities spread over more than 100 km. Totally, more than 300 samples were collected from about 40 sampling sites. Stepwise thermal demagnetization up to 700°C revealed a stable component of magnetization of either polarity in 25 sites. The fold test and the reversal test for this component are positive, which is usually regarded as a sound argument in favor of the primary origin of magnetization. However, the Basu paleomagnetic pole (longitude 187.3°E, latitude 1.1°N) is located near the Late Ordovician-Early Silurian segment of the apparent polar wander path for Baltica, which might indicate a Paleozoic remagnetization of Vendian rocks. In this work we analyze different interpretations of the obtained results and evaluate the reliability of the Late Riphean and Vendian paleomagnetic data for Baltica.  相似文献   

Evaluation of conditions under which unprotected parts of the human body may freeze in urban air during winter

Relationships between the human skin temperature and a combination of air temperature and wind speed are obtained. These relationships have been used to estimate the climatic conditions leading to the possible freezing of unprotected parts of the face in urban air during winter.The possibility of utilizing relationships governing the heat balance of man, including nomograms and graphs constructed for estimating climatic conditions in urban areas, for isolating zones of different functional importance in the boundaries of a subdivision and of a city, and for estimating the efficiency of various architectural designs in improving the microclimate, are discussed.Originally published inTrudy Main Geophys.
