Geochemistry and petrogenesis of Cretaceous oceanic plateau lavas in eastern Jamaica
, 2008 Basaltic lavas of Turonian to Coniacian age belonging to the Bath–Dunrobin Formation occur with intercalated island arc tuffs in the south of the Blue Mountain inlier, have been interpreted as being derived from the Caribbean oceanic plateau.

Jurassic–Paleogene intraoceanic magmatic evolution of the Ankara Mélange, north-central Anatolia, Turkey [PDF]
Solid Earth, 2014 Oceanic rocks in the Ankara Mélange along the Izmir–Ankara–Erzincan suture zone (IAESZ) in north-central Anatolia include locally coherent ophiolite complexes (~ 179 Ma and ~ 80 Ma), seamount or oceanic plateau volcanic units with pelagic and reefal ...

Buckling of the oceanic lithosphere from geophysical data and experiments
, 1992 Two major hypothesis have been advanced for the formation of the long wavelength (100-300) km undulations of oceanic basement and overlying sediments developed in the central Indian Ocean: whole layer folding (buckling) and local thickening (inverse ...

Cagayan Valley Basin, North Luzon, Philippines: subduction, rotation and rift product?
Geoscience LettersRecent investigations confirm the existence of a west-dipping Cretaceous-Paleogene subduction zone offshore of North Luzon. This tectonic feature can account for the formation of an Eocene arc that subsequently separated into the Central Cordillera Arc ...

Lithospheric long-wavelength magnetic anomalies and their geological origins: A review
地球与行星物理论评At the altitude of low-Earth-orbiting satellites, most details of lithospheric magnetic anomalies observed near surface are attenuated, and only slowly decaying long-wavelength magnetic anomalies can be detected.

Origin of the Aves Ridge and Dutch–Venezuelan Antilles : interaction of the Cretaceous ‘Great Arc' and Caribbean–Colombian Oceanic Plateau? [PDF]
, 2011 In this paper we reassess the geochronology and geochemistry of three dredge hauls from the SE corner of the Aves Ridge (Caribbean Sea) originally sampled in 1968 by Duke University's R. V. Eastward. Two hauls consist of light rare earth element-enriched

Role of precession on the transition seasons of the Asian monsoon
npj Climate and Atmospheric Science, 2023 While there have been many paleoclimate studies on the precessional control of climate, typically only the orbital phase where perihelion occurs close to the solstices has received attention. Here, we explore how precession affects the seasonal evolution
