对加拿大的伯思利汉姆贾和瓦利斑岩铜矿床的花岗岩中Rb和Sr的地球化学扩散现象的研究表明,Rb含量从矿体的边缘向中心部位增加,而Sr含量则从外缘向矿体的中心减低,产于安山岩内的奇里安斑岩铜矿床中,Rb和Sr的分布亦是如此,在有蚀变带的岩石中,这两种元素的分布可作为有价值的找矿标志.在美国西南部,为了用地球化学手段评价隐伏的斑岩铜矿靶区.有几个史刊正在研究之中.查菲研究了亚利桑那洲卡拉马祖斑岩铜矿的岩心和钻孔岩
Studies on the geochemical diffusion of Rb and Sr in the granites of the Bethlehemjar and Valigny porphyries in Canada show that the Rb content increases from the edge to the center of the ore body while the Sr content increases from the outside The center of the marginal orebodies is reduced and is also found in the Qilian porphyry copper deposit within the andesite, as is the distribution of Rb and Sr. In rocks with altered zones, the distribution of these two elements can be described as Value prospecting marker In the southwestern United States, several geographies are under investigation for the geochemical evaluation of buried porphyry copper targets, and Chafee studied the core of the Kalamazoo porphyry copper deposit in Arizona And borehole rock
