Abstract: The mechanisms and processes by which subducted slab interacted with mantle plume remain controversial, as direct observation of such interaction is difficult to impossible. Compositional heterogeneity of large igneous provinces (LIPs) additionally makes plume-slab interaction hard to detect. Oxygen isotopes are sensitive enough to trace the source of magmas. Here we provide evidence for plume-slab interaction mainly based on in situ zircon Hf-O isotope analyses, as well as whole-rock elemental and Sr-Nd-Hf isoto...

Messelopython freyi remains were recovered from a quarry near Darmstadt The head and body of Messelopython freyi are 'almost completely preserved' Scientists have identified the world's earliest python from 47 million-year-old fossils recovered from a quarry in southwest Germany.  Remains of the new python species, called Messelopython freyi, were discovered in Messel Pit, a UNESCO World Heritage Site near the German city of Darmstadt. ADVERTISEMENT Researchers report in a new paper that the 'completely preserved' species had a length of just over three feet (one metre).  M. freyi, both ...
