在挪威西部片麻岩地区的(?)橄榄岩研究中,变质榴辉岩显示异常的Sr浓缩,在全岩分析中SrO最大为2.4%。在变质榴辉岩矿物中存在的最大Sr浓度是:斜长石9.6% SrO,绿帘石8.5%,黝帘石7.4%斜黝帘石4.7%,杆沸石6.65%,磷灰石1.5%,葡萄石0.5%,榍石0.3%,角闪石0.2%以及Sr-长石22.6%。锶异常是由于榴辉岩在角闪岩化作用期间Sr带入而形成的。被带入的Sr的来源或许是邻近的角闪岩和在晚加里东期带入的。晶体化学研究表明,根据晶体化学现有的知识和痕量元素分布很可能能够预见在矿物相之间Sr的分布。
Metamorphic eclogites show unusual Sr concentration in the (?) Peridotite study in western Norway gneiss, with a maximum of 2.4% SrO in the whole rock analysis. The maximum concentrations of Sr present in the metamorphic eclogite minerals are: plagioclase 9.6% SrO, epidote 8.5%, zoisite 7.4% diazite diorite 4.7%, rod zeolite 6.65%, apatite 1.5% 0.5% grape stone, 0.3% limestone, 0.2% amphibole and 22.6% Sr-feldspar. Strontium anomalies result from the incorporation of Sr into the amphibolite during amphibolite lithification. The source of Sr brought in may be adjacent amphibolite and brought in late-Caledonian. Crystallographic chemistry studies have shown that it is possible to predict the distribution of Sr between mineral phases based on current knowledge of crystal chemistry and trace elemental distribution.
