Paleomagnetism of ultramafics from the Konder Massif and its age assessment

The petro- and paleomagnetic studies of ultramafic rocks (dunites, clinopyroxenites, kosvites) from the Konder Massif revealed the primary thermal remanance nature of the defined characteristic magnetization components. The calculated coordinates of the paleomagnetic poles are as follows: Plat = −4°, Plong = 178°, d_p = 5°, and d_m = 8° for the dunites; Plat = −2°, Plong = 181°, d_p= 6°, and d_m = 10° for the clinopyroxenites; and Plat = 71°, Plong = 206°, d_p = 5°, and d_m = 6° for the kosvites. Based on paleomagnetic and petromagnetic data, the age is estimated to be the Early Neoproterozoic for the dunites and clinopyroxenites and the Early Cretaceous for the kosvites. The massif as a whole is dated back to the Early Neoproterozoic (1000–950 Ma).
