"Dating zircon grains using ... techniques is now celebrated as the optimal method for determining when igneous rocks formed," the report said. The technique involves measuring the decay of ...

Russia has officially unveiled the Zircon hypersonic missile, capable of reaching speeds of Mach 9—over 10,000 kph—at altitudes of 20 km. President Vladimir Putin described it as a "strategic ...

Additional features included erasure of igneous zoning, dissolution of crystal edges, and metamict structures. Thus, the external morphology and internal textures of the crystals helped identify ...

This pattern, called oscillatory zoning, indicates that incorporation of these elements into the zircon occurred during its igneous history, in magma. The problem is that iron, aluminium and ...
