Diffusion chronometry has become a significant tool for the determination of the duration and rates of a variety of volcanic and other magmatic processes. These include the determination of residence times of magmas in sub-surface reservoirs and ascent rates of melts through the crust or mantle. It also has applications in a number of other areas such as the determination of exhumation rates of mountain belts, discerning the nature of tectonics on the early Earth, or in testing the reliability of palaeotemperatures obtained from studies of fossil shells. However, software tools for easy but robust application of the method are not yet available. This proposal aims to develop such tools. Some of the features that would be included in the tools are diffusion in non-isothermal systems that include several minerals and melts interacting with each other, and undergoing dissolution or growth during diffusion. The results will be made accessible to the community free of cost through different scientific channels.

扩散时间表已成为确定各种火山和其他岩浆过程的持续时间和速率的重要工具。这些包括确定地下储层中岩浆的停留时间以及通过地壳或地幔的熔体的上升速率。它还在许多其他领域都有应用，例如确定山带的挖掘速率，辨别地球早期的构造性质，或测试从化石壳研究中获得的古植物的可靠性。但是，尚不可用的软件工具可轻松但可靠的方法应用。该建议旨在开发此类工具。工具中将包含的一些特征是在非等热系统中的扩散，其中包括几种矿物质和融化相互作用，并在扩散期间经历溶解或生长。该结果将通过不同的科学渠道免费为社区访问。
