fulgurite वाक्य

The Winans Lake fulgurite [ s ] ( Winans Lake, Livingston County, Michigan ), extended discontinuously throughout a 30 m range, and arguably includes the largest reported fulgurite mass ever recovered and described-its largest section extending approximately 16 ft ( 4.88 m ) in length by 1 ft in diameter ( 30 cm ).
In addition, Wickramasinghe's team remarked that the temperature at which sand must be heated by lightning to melt and form a fulgurite ( 1770 �C ) would have vaporized and burned all carbon-rich organisms and melted and thus destroyed the delicately marked silica frustules of the diatoms, and that the oxygen isotope data confirms its meteoric origin.
