Interpretations of Rb–Sr and Sm–Nd data from the Grunehogna Granite demonstrate that anatexis of and mixing with Høgfonna Formation sedimentary rocks, caused by hot basic sills of ~1100 Ma Borgmassivet Suite, are consistent, with the granite εNdεSr_100Ma data, partially overlapping Borgmassivet Suite data and are marginally displaced toward published data from the Høgfonna Formation. Upper intercept LA-ICPMS U–Pb data from the Grunehogna Granite and Borgmassivet Suite zircons are within error at 1088 ± 17Ma and 1088 ± 68Ma, and are consistent with with unpublished data for the gabbro of 1107Ma. Interpretations of syn-depositional anatexis of semi-consolidated sediments under, high pH₂O, are consistent with deposition at ~1130-1107Ma for the Høgfonna Formation. Sm–Nd data define an age of 3058 ± 116Ma for the Annandagstoppane Granite, consistent with a reported U–Pb zircon age of 3067± 8Ma. Rb–Sr data for the Annandagstoppane Granite define an errorchron of 2252 ± 82Ma. Differences between Rb–Sr and Sm–Nd data suggest that Rb–Sr systematics in many samples from all units have experienced open system behaviour in contrast to Sm–Nd systematics from which no disturbance is apparent. Localised tonalitic partial melts of gabbro yield an upper intercept LA-ICPMS U–Pb age from zircon of 1114 ± 47Ma.

对来自 Grunehogna 花岗岩的 Rb-Sr 和 Sm-Nd 数据的解释表明，由 ~1100 Ma Borgmassivet Suite 的热基性基岩引起的 Høgfonna 组沉积岩的退烧和混合是一致的，与花岗岩 εNdεSr _100Ma数据部分重叠Borgmassivet Suite 数据与来自 Høgfonna 地层的已发布数据略有不同。Grunehogna 花岗岩和 Borgmassivet Suite 锆石的上截距 LA-ICPMS U-Pb 数据误差在 1088±17Ma 和 1088±68Ma，与未发表的 1107Ma 辉长岩数据一致。半固结沉积物在高 pH ₂条件下的同沉积厌氧处理的解释O，与 Høgfonna 组在~1130-1107Ma 的沉积一致。Sm-Nd 数据定义了 Annandagstoppane 花岗岩的年龄为 3058±116Ma，与报道的 U-Pb 锆石年龄 3067±8Ma 一致。Annandagstoppane 花岗岩的 Rb-Sr 数据定义了 2252 ± 82Ma 的误差时间。Rb-Sr 和 Sm-Nd 数据之间的差异表明，来自所有单元的许多样本中的 Rb-Sr 系统都经历了开放系统行为，而 Sm-Nd 系统则没有明显的扰动。辉长岩的局部斜长岩部分熔体产生了 1114±47Ma 锆石的上截距 LA-ICPMS U-Pb 年龄。
