We propose a half-year pilot project for a detailed study of the interrelations between mineralizing and deformation processes in the Archaean to Proterozoic Carajás Transcurrent System, Brazil. The recent release by the CVRD mining company of an enormous database of exploration borehole logs plus orientated core material and access to newly created outcrops raises the opportunity to investigate the 3D geometry of the mineral deposits and their structural setting on various spatial scales and in unprecedented accuracy. We intend to develop a stochastic model of the deposits from a subset of the total dataset and test its predictive capacities on another subset. If this approach yields promising results, the full project aiming at a model of the entire available volume will be scheduled for a one year duration. Both the pilot study and, if applicable, the successor project will build on the results of a more classical structural study already under way in partnership with the universities of Belém and Durham.

我们提出了一个半年的试点项目，以详细研究对巴西的古生代Carajásthragerrent System的矿化和变形过程之间的相互关系。 CVRD矿业公司最近发布了一个巨大的勘探钻孔日志数据库以及面向核心材料以及对新创建的露头的访问，这增加了研究矿物质沉积物及其在各种空间尺度上以及以前未经预言的矿物沉积物及其结构环境的3D几何形状的机会。我们打算从总数据集的一个子集中开发出沉积物的随机模型，并在另一子集上测试其预测能力。如果这种方法产生了承诺结果，那么整个项目的目标是针对整个可用音量的模型，将安排一年的持续时间。试点研究和连续项目都将基于与贝莱姆和达勒姆大学合作的一项更古典的结构研究的结果。
