Review of the Ediacaran-Lower Ordovician (pre-Sardic) stratigraphic framework of the Eastern Pyrenees, southwestern Europe
The Ediacaran-Lower Ordovician successions exposed in the Eastern Pyrenees are updated and revised based on recent U-Pb zircon radiometric ages, rumchata proof intertonguing relationships of carbonate-dominated strata, and onlapping patterns marking the top of volcano-sedimentary complexes.A stratigraphic comparison with neighbouring pre-Variscan o
Some aspects of determining and applying criteria for the rejecting and the forecasting of canon tube remaining service life
The paper points out disadvantages and ambiguities of existing criteria for canon tubes condition determination as well as of for casting methods for their remaining service life.A possible approach read more in making decisions about corrective maintenance actions is given, particularly when concerning modern artillery weapons in which the applica
