一个简单的方法可以提供更深入的了解岩浆系统演化的途径和时间尺度。该方法，采用同位素指纹的矿物成分的特点，大多数岩浆岩，可能会导致这些类型的岩石更全面的了解。这种认识对于解决从地壳和地幔的起源和分化到火山灾害预测等地球科学中的基本问题至关重要。在过去的30至40年里，已经取得了很大的进展，首先是广泛应用于自然和合成系统的实验研究，最近是应用化学和同位素限制火成岩的起源。然而，尽管取得了这些进展，许多问题仍然存在，这就是同位素指纹技术可能有所帮助的地方。
A simple method may provide greater insights into the sort of pathways and time-scales in which magmatic systems evolve. The method, employing isotopic fingerprinting of the mineral components that characterize most magmatic rocks, may lead to a more comprehensive understanding of these types of rocks. Such an understanding is critical to resolving fundamental problems in geoscience, ranging from the origin and differentiation of the crust and mantle to the prediction of volcanic hazards. Much progress has been made in the past 30 to 40 years, first with the widespread application of experimental studies on natural and synthetic systems, and more recently with the application of chemical and isotopic constraints on the origin of igneous rocks. Despite this progress, however, many questions remain, and that is where isotopic fingerprinting may help.
