User friendly codes for the generalized application of diffusion chronometry

扩散计时法已成为确定各种火山和其他岩浆作用持续时间和速率的重要工具。这包括确定岩浆在地下储集层中的停留时间和熔体通过地壳或地幔的上升速率。它在其他一些领域也有应用，如确定山脉带的折返速度，辨别早期地球上的构造性质，或测试从化石贝壳研究中获得的古温度的可靠性。然而，目前还没有简单而有力地应用该方法的软件工具。这项提议旨在开发这样的工具。工具中将包括的一些特征是在非等温系统中扩散，该系统包括几种相互作用的矿物和熔体，并在扩散过程中经历溶解或生长。结果将通过不同的科学渠道免费向社会公布。

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.
