Precise Pb.E2.80.93Pb dating of meteorites Lead–lead dating

pb–pb isochrons oldest known material in solar system. chondrules , calcium–aluminium-rich inclusions (cais) spherical particles make chondritic meteorites , believed oldest objects in solar system. hence precise dating of these objects important constrain evolution of solar system , age of earth. u–pb dating method can yield precise ages solar-system objects due optimal half-life of u. however, absence of zircon or other uranium-rich minerals in chondrites, , presence of initial non-radiogenic pb (common pb), rules out direct use of u-pb concordia method. therefore, precise dating method these meteorites pb–pb method, allows correction common pb. when abundance of pb relatively low, isotope has larger measurement errors other pb isotopes, leading strong correlation of errors between measured ratios. makes difficult determine analytical uncertainty on age. avoid problem, researchers developed ‘alternative pb–pb isochron diagram’ (see figure) reduced error correlation between measured r...

Understanding the dangers Tornado preparedness

a tornado no obvious funnel upper clouds, although rotating dust cloud indicates strong winds @ surface. a tornado operates rotating, funnel-shaped cloud extends downward thunderstorm, ground, swirling winds have reached 300 miles per hour (480 km/h). wind speed might difficult imagine: traveling length of u.s. football field within 1 second (over 130 meters or 430 feet per second). damage paths have been in excess of one-mile wide (1.6 km) , 50 miles long (80 km). not tornadoes seen. tornado funnel can transparent until reaching area loose dirt , debris. also, tornadoes have been seen against sunlit areas, rain or nearby low-hanging clouds has obscured other tornadoes. occasionally, tornadoes have developed suddenly, rapidly, little, if any, advance warning possible. before tornado strikes area, wind has been known die down , air become still. cloud of debris has marked bottom of tornado when funnel not visible. tornadoes typically occur along trailing edge of thundersto...
