The chapter focuses on Virginia east of the Blue Ridge, a region whose population in the years between 1760 and 1860, was roughly half white and half non-white, half free and half slave. Tilting the balance was a middle group of people who were free but not white. It takes another ...
Excavations on Jerusalems Southeastern Ridge, in the Givati Parking Lot excavations, have exposed a man-made ditch, some 30 m wide and at least 6 m in depth, close to the hills summit. This paper presents the technical features of the ditch, including the rock scarps that delineate it ...

Such a control of old continental lineaments over the segmentation pattern of a developing spreading ridge has probably not only occurred in the Red Sea, but, in a much broader sense, can be applied to the segmentation of mid-ocean ridges in general. 展开 ...

Formation of continental crust has shaped the surface and interior of our planet and generated the land and mineral resources on which we rely. However, how the early continental crust of Earth formed is still debated1,2,3,4,5,6,7
As a result of the study on the phosphate de- posits of the hilly region 5 km east of Chengjiang (Chengchiang),Yunnan,the Sinian and Cambrian stratigraphy has been investigated by C.S.Ho (1942).The different stratigraphical units so far ... WT Zhang - 《Acta Palaeontologica Sinica》 ...
In addition, U–Th–total Pb dating of neoblastic overgrowths on detrital monazite gave an age of 1488 ± 20 Ma, and recrystallized hematite in folded metapelite gave a mean U/Th–He age of 1411 ± 39 Ma. Post-Baraboo, arkosic polymictic conglomerate, which contains detrital zircon ...
D. Frank Taylor expanded on Eduard Suess’s theory of continental drift by arguing that tidal forces 100 million years ago had broken continents apart and caused the rise of the Mid-Atlantic Ridge. E. Alfred Wegener, who first developed the theory of continental drift argued that all landmasse...
We performed leave-one-out cross-validation using the function ‘cv4abc’ on randomly selected simulations, and report the prediction error, calculated as for each analysis. At most, the prediction error was 0.5111 s.d.’s away from zero, and so we observe that the analysis has performed wel...
