什么是 Ratio–ratio diagram？

又称： ratio--ratio diagram

Definition 12.10 University Earth and Space Sciences — Year 3 · 第 12 章 — Trace-Element Modelling

A ratio–ratio diagram plots, for a suite of lavas, the ratio of a highly incompatible element $H$ to a less incompatible one $M$ against the concentration of $H$ (or against another ratio). Partial melting, crystallisation and mixing draw lines of different shapes on it.

Batch melts of a primitive-mantle source on a La/Yb against La diagram, for a spinel and a garnet lherzolite, with ticks at F = 1, 2, 5, 10 and 20\,\%, and the two invented lavas of the weekend problem. Each lava sits on one curve only. — Batch melts of a primitive-mantle source on a La/Yb against La diagram, for a spinel and a garnet lherzolite, with ticks at $F = 1$ , 2, 5, 10 and $20\,\%$ , and the two invented lavas of the weekend problem. Each lava sits on one curve only.
