摘要
瓦尔特相律是现代沉积学的主要理论基础之一。1960年 Weller,J·M·以图解的方式对瓦尔特相律进行了解释,这一图解至今仍被许多沉积学专著所引用。笔者认为该图解并没有反映出瓦尔特相律的本质。为此,笔者对该图解进行了修正和补充。新图解通过等时面的标定,从岩相间的连续变化性和岩相的穿时性等方面反映了瓦尔特相律的本质——岩相的侧向迁移。
Walther phase-rule is one of the basic theories on modern sedimentology interpretedby Weller in the way of diagram in 1960,which have still been quoted by many treati-ses on sedimentology up to now. The auther considers that the diagram hasn't reflect thenature of Walther's phase-rule, revises and complements it in this paper. In the aspectsof demarcation to isochron surfaces, of continuous variations among lithofacies, ofdiachronous of lithofacies, the new diagram represents the nature of Walther's phase-rule, that is lateral migration of lithofacies.
