Using isotope signatures as a validation tool for GCMs, the Australian team discovered that these models were not properly taking into account evaporation from open water in the Amazon river system, and not correctly simulating transpiration by the rainforest as compared to normal evaporation from rivers, ponds and other settled water.
Although not organized as such in the layout, I found that individual chapters in the book can be divided into four categories: i) those that concentrate on isotope geochemistry, ii) those that concentrate on isotope technology/methodology, iii) those that concentrate on major/trace element geochemistry, and iv) those that review a mineral deposit type.
