Mass transfer of elements occurs within the earth on a continual basis and where there is sufficient concentration of elements ore deposits or natural resources occur. Elemental transfer occurs in many ways, but magmatic and metamorphic processes are two very significant and widespread ones that have been active through earth history. The study of elemental mobiization on different scales through time and how intra-element associations relate to earth processes is necessary in order to: (1) understand earth evolution, (2) how processes within the earth evolve through time, and (3) how natural resources form and relate to earth evolution. This proposal examines two aspects of mass transfer of elements: (1) the association of different gold deposits and tin, tungsten, molybdenum deposits in a range of environments within a single large geological area (1000s sq. km). This study is then used to examine how such elemental associations relate either independently or collectively to the geological evolution of such regions elsewhere globally; and (2) the processes that are responsible for the mobilization and concentration of tantalum, an element of relevance to societal needs, but also used in understanding earth evolution and important geological processes through time.

元素的质量转移在地球内部持续发生，并且元素矿床或自然资源足够集中。元素转移以多种方式发生，但岩浆和变质过程是两个非常重要且广泛的过程，在地球历史上一直很活跃。研究元素随时间在不同尺度上的迁移以及元素内关联如何与地球过程相关是必要的，以便：（1）了解地球演化，（2）地球内部的过程如何随时间演变，以及（3）如何自然资源的形成并与地球的演化相关。该提案研究了元素质量转移的两个方面：（1）在单个大地质区域（数千平方公里）内的一系列环境中不同金矿床和锡、钨、钼矿床的关联。然后，这项研究用于研究这些元素关联如何独立或集体地与全球其他地区这些地区的地质演化相关； （2）负责钽的动员和浓缩的过程，钽是一种与社会需求相关的元素，但也用于理解地球演化和重要的地质过程。
