摘要 豫西石炭二叠纪煤系各主要煤层中的硫分均呈西高东低的分布,但从古地理条件分析,煤系形成时海侵自东和南东而来,这一现象多年来一直没有得到合理的解释。豫西自元古代以来就有大量火山喷发,一直延续到古生代,这些火山岩就是豫西煤中流的重要来源。 Sualphur content in main Permo-carbonifero. s coal seams in western Henan province distribtites high in the west and Iow in the east. while the sea intrusion during the formation of the coal series was from the east and southeast in accordance with the Paleogeographical condition analysis.That has not been found a reasonable explanation for many years Howaver, there had been a great deal of volcanic eruPtion since Papeozoice era to Papozoic era It is those volcanic rock that are zhe main source of the Sulphur in coats in western Henan province.
