Basement structure of the northern Ontong Java Plateau [PDF]
, 1993 Site surveys conducted in conjunction with Leg 130 on the Ontong Java Plateau reveal a strong seismic reflector at 0.8 to 1.0 s below the seafloor that drilling at Sites 803 and 807 confirmed is Cretaceous basalt.

Two Acheuleans, two humankinds. From 1.5 to 0.85 Ma at Melka Kunture (Upper Awash, Ethiopian highlands) [PDF]
, 2017 The Acheulean is the longest-lasting human cultural record, spanning approximately 1.5 Ma and three continents. The most comprehensive sequences are found in East Africa, where, in large-scale syntheses, the Lower Pleistocene Acheulean (LPA) has often ...

Eos, Transactions American Geophysical Union, 2006 My mother, who was born under Austria's emperor but died in New York, often cited a German rhyme which she attributed to the renowned German poet Johann Wolfgang von Goethe (1749–1832): Amerika, du hast es besser Hast keine Basalte und keine Schloesser, or America, you have it better Hast no basalts and no castles.

Thermal fluctuation fields in basalts [PDF]
Earth, Planets and Space, 2009 AbstractThe thermal fluctuation field (Hf) is central to thermoremanent acquisition models, which are key to our understanding of the reliability of palaeomagnetic data, however,Hfis poorly quantified for natural systems. We reportHfdeterminations for a range of basalts, made by measuring rate-dependent hysteresis.
