This study shows lithosphere evolution history in the west North China Craton (NCC) from the early Cretaceous to Quaternary by studying the major element, trace element and Sr-Nd-Hf isotope compositions in Jining basalts of 119.6108.6 Ma, 23.521.9 Ma and 1.30.11 Ma.The early Cretaceous basalts (119.6108.6 Ma) display enriched characteristics with high contents of incompatible elements, high 87 Sr/ 86 Sr i , low ε Nd (t) and low ε Hf (t). These basalts resulted from partial melting of ancient metasomatized lithospheric mantle, and we consider the 119.6108.6 Ma magmatism as indicating lithosphere thinning in the west NCC. Although the Pacific slab seen seismically in the mantle transition zone beneath eastern China is no older than 60 Ma, there exists convincing evidence for the presence of the Paleo-Pacific slab in the transition-zone in the Mesozoic. Thus we propose that the water released from the transition-zone slab hydrated A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTthe overlying lithosphere and further converted the base of the lithosphere into asthenosphere. This is the most likely mechanism responsible for the lithosphere thinning in the west NCC and the petrogenesis of the Jining 119.6108.6 Ma basalts. Sr i , high ε Nd (t) and high ε Hf (t). Upwelling and decompression melting of the eastward flowing asthenosphere from beneath western plateaus to beneath eastern hilly plains in the Cenozoic is the most plausible mechanism for the petrogenesis of Jining Cenozoic basalts (both of 23.521.9 Ma and 1.30.11 Ma), but the Jining 1.30.11 Ma basalts must have been produced beneath even thinner lithosphere.Taken together geophysical studies and our petrological and geochemical studies of all these three episodes of the Jining basalts, wepropose that the lithosphere in the west NCC has been thinning since the early Cretaceous and the thinning continues to the present.

“…Integrating the isotopic ratios with the element compositions, the Cenozoic basalts from the Taihang Mountains are inferred to be derived from partial melting of an asthenospheric source with different degrees of the involvement of old lithospheric mantle.

Thermally induced inversion of Al‐substituted titanomagnetite in basalts: Evidence for partial self‐reversal

et al. 2006

[1] We report properties of laboratory-induced thermoremanence combined with detailed rock magnetic experiments on basaltic samples which contain aluminum-substituted titanomagnetite (Fe 2.24 Ti 0.64 Al 0.12 O 4 ). Prior to Thellier-Coe paleointensity experiments, specimens were first demagnetized using an alternating field with a peak field of 90 mT and were then imparted an anhysteretic remanent magnetization (ARM) to represent a natural remanent magnetization (NRM). Results show that the partial thermal remanent magnetization (pTRM) gain and ARM remaining are linearly correlated up to 300°C. Between 300 and 460°C, specimens acquire thermoremanence with a direction antiparallel to the external field direction, leading to intensity decreases. This coincides with the onset of the mineral transformation from Al-titanomagnetite to a magnetic phase with higher T c . Our results support that phase interaction with distinct T c values in partially oxidized titanomagnetite can produce partial self-reversal thermoremanence in rocks.Citation: Pan, Y., Q. Liu, C.
