Ages on weathered Plio-Pleistocene tephra sequences, western North Island, New Zealand [PDF]

, 2001
Using the zircon fission-track method, we have obtained five ages on members of two strongly-weathered silicic, Pliocene-Pleistocene tephra sequences, the Kauroa and Hamilton Ash formations, in western North Island, New Zealand.

BADDELEYITE MINERALIZATION OF ULTRAMAFIC ROCKS FROM THE MAIN URALS COLLISIONAL SUTURE (UFALEY METAMORPHIC BLOCK, CENTRAL URALS) [PDF]

Минералогия, 2016
Baddeleyite from ultramafic rocks of the Kurta eclogite-schist megamélange (Ufaley metamorphic block, Central Urals) is studied. The zirconium mineralization is established in Ni-bearing forsterite and magnetite-forsterite rocks, which were replaced by ...
