The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

Mantle plumes originate at depths near the core− mantle boundary (~ 2,800 km). As such,
they provide invaluable information about the composition of the deep mantle and insight …

Basalts and basaltic rocks are the most abundant igneous rocks on the earth and their
petrologic and geochemical studies have formed our knowledge base on the thermal …

Whether the two large low–shear velocity provinces (LLSVPs) at the base of Earth's mantle
are wide compact structures extending thousands of kilometers upward or bundles of distinct …

An Introduction to Seismology, Earthquakes and Earth Structures is an introduction to
seismology and its role in the earth sciences, and is written for advanced undergraduate and …

On the basis of geological, geochemical and geophysical data of Late Mesozoic igneous
rocks in SE China, we suggest that during the period from 180 to 80Ma, the slab dip angle of …

Large igneous provinces (LIPs) are a continuum of voluminous iron and magnesium rich
rock emplacements which include continental flood basalts and associated intrusive rocks …

Abstract Morgan [1, 2] suggested that continental flood basalts appear as the first volcanic
expression of new mantle plumes. Experimental studies in viscous liquids have shown that …

The origin of mantle hotspots is a controversial topic. Only seven ('primary') out of 49
hotspots meet criteria aimed at detecting a very deep origin (three in the Pacific, four in the …

Corrosion of iron presents a serious economic problem. Whereas aerobic corrosion is a
chemical process, anaerobic corrosion is frequently linked to the activity of sulphate …
