摘要
本文论述了第一旋回砂／砂岩成分作为古气候恢复标志的基本原理，介绍了砂／砂岩粒径—成分趋势，砂／砂岩的骨架成分图解和ＲＦＰ指数（火山岩岩屑／斜长石十火山岩岩屑）在古气候恢复中的应用。
In this paper,the basic principle of the first-cycle sand/sandstone compositions as a pale-oclimatic recovery indicator is discussed.Sand sandstone grain size compositional trend,theapplication of framework composition and RFP index(Volcanic frgments/Plagioclases+Vol-canic fragments)in paleoclimate recovery are introduced.
