A potential zircon reference material ( BB zircon) for laser ablation‐inductively coupled plasma‐mass spectrometry LA ‐ ICP MS ) U‐Pb geochronology and Hf isotope geochemistry is described. batch of twenty megacrysts (0.5–1.5 cm 3 from Sri Lanka was studied. Within‐grain rare earth element REE compositions are largely homogeneous, albeit with some variation seen between fractured homogeneous domains. Excluding cathodoluminescence bright domains, the in U content all analysed crystals ranged...
Plutonic rocks from the Mineiro Belt, Brazil record a delayed onset of transition TTG to sanukitoid-type magmatism (high Ba-Sr), starting during Siderian magmatic lull when little juvenile magma was added continental crust. Rocks mostly belong calc-alkaline series, meta- peraluminous and originally "I-type", meaning that oxidized magmas were formed by partial melting subducted material. The temporal distribution apparent secular changes are consistent with subduction-driven plate tectonics...
Recent improvements in laser ablation and multicollector (MC)-ICP-MS technology offer higher sensitivity, robust stability, larger dynamic ranges.
