| 摘 要： | 华北石炭二叠煤系中的Ｉ／Ｓ间层粘土岩夹矸或粘土岩层，在太行山以东较为发育。Ｉ／Ｓ间层矿物的类型有累托石、ＩＳ有序间层矿物、Ｓ／Ｉ无序间层矿物，它们是在近岸泥岩沼泽或沼泽环境中由同期降落的火山灰蚀变而成，在酸性介质的影响下，形成ＩＳ有序间层矿物，在偏碱性的介质条件下，形成Ｓ／Ｉ无序间层矿物；高压异常区则形成累托石。

| Abstract: | /S clayrock bands and beds of Carboniferous-Permian Coal-bearing Formation in Northern China have wider distribution in the eastern Taihang Mountain. Tie types of I/S interstratified mineral have rectorite,ordered IS and disordered S/I.They were formedby the.synsedimentary fallout ash alteration in the nearshore peat swamp and march environment.The ordered IS minerals were formed in.acidity medium the disordered S/I minerals formed in the alkaline one,and tie rectorite was formed in the abnormal regions of high pressure. |
