Profound geotectonic, climatic and biological changes occur during the terminal Neoproterozoic and its transition into the early Cambrian. These are reflected i
The early Paleozoic alkali dyke swarms in the Ziyang-Langao areas of south Qinling are characterized by bimodal volcanic association. They show the patterns of
The SdP, pdP and sdP phases are picked up with the Nth root slant stack method from the digital waveform data recorded by the networks and arrays in USA, Germany and Switzerland for the earthquakes oc
We here report the first case of rodingites that were formed at the expense of eclogite enclosed in the ultramafic rocks of Changawuzi ophiolites. The rodingite
Sm-Nd isotopic characteristics, εNd(t) values and Nd model ages (TDM) of Proterozoic metasedimentary rocks in the eastern segment of Central Tianshan Belt (ESC
High-pressure mafic granulites, occurring as lenses within gneisses and quartzite in the central segment of the Himalayan orogen, were dated using SHRIMP U-Pb t
Measurement of clay mineralogy at ODP Site 1146 in the northern South China Sea (SCS) indicates that illite, chlorite, and kaolinite contents increased during g
Well-preserved Mesozoic vertebrate fossils were found from lacustrine deposits interbedded with tuff and tuffites in the lower part of the Yixian Formation, wes
Based on the row structure model of Kimes and the mean gap probability model in single direction, we develop a bidirectional gap probability model for row crop
