“…Although the province boundaries are roughly latitudinal, more detailed research shows an irregular flora distribution in the southern Sikhote‐Alin (Figure ). Plants from the southernmost Sikhote‐Alin are similar to the Ryoseki‐type flora, whereas some areas in the Sikhote‐Alin are assigned to the mixed‐type flora domain (Golozoubov et al, ; Kimura, ). Tectonic reconstruction based on the floral assemblages in East Asia indicates that northward movement could be more than 5° of latitude in SW Japan and 15° of latitude in the southern Sikhote‐Alin (Golozoubov et al, ).…”

The Sikhote‐Alin orogenic belt in Russian Far East is comprised of several N‐S trending belts, including the Late Jurassic to Early Cretaceous accretionary prisms and turbidite basin which are now separated by thrusts and strike‐slip faults. The origin and collage of the belts have been studied for decades. However, the provenance of the belts remains unclear. Six sandstone samples were collected along a 200 km long east‐west traverse across the major belts in the southern Sikhote‐Alin for U‐Pb dating and Lu‐Hf isotope analysis to constrain the provenance and evaluate the evolution of the northwest Pacific margin at this time. The result reveals that the sediments from the main Samarka belt was mainly from the adjacent Bureya‐Jiamusi‐Khanka Block (BJKB); the eastern Samarka belt and the Zhuravlevka turbidite basin were supplied by detritus from both the North China Craton (NCC) and the BJKB; the Taukha belt was mainly fed by sediments from the NCC; whereas the data from the Sergeevka nappes are insufficient to resolve their provenance. In the Late Jurassic to Early Cretaceous, collision and subduction was important in the initial collage of most belts in Sikhote‐Alin. However, merely E‐W trending collage cannot explain the increasing importance of the NCC provenance from west to east. It is proposed that the main Samarka belt was located adjacent to the BJKB when deposited, whereas the other belts were farther south to accept the materials from the NCC. Sinistral strike‐slip faulting transported the eastern belts northward after their initial collage by thrusting.

“…A left-lateral strike-slip movement along the continental margin faults may have occured, displacing the eastern block northward relative to stable Eurasia (North China block, South China block and Siberia) (Xu et al, 1989;Xu, 1993;Otofuji and Matsuda, 1983;Golozoubov and Khanchuk, 1996). Some tectonic reconstructions suggest that the terranes of Inner Japan were displaced about 5°northward, while the terranes of Outer Japan were displaced about 15°north of their original position (15-30°N) (Golozoubov et al, 1999;Lee, 2008), but recent works minimize the importance of these displacements (Ito et al, 2009;Isozaki et al, 2010).…”

“…As can be seen, palaeoclimatological interpretation of palaeobotanical data for the Mesozoic of Asia (based either on pollen or leaf fossils) is difficult, and results have not been unanimously approved (Umetsu & Sato 2007). Phytogeography could help, but this is still one of the most controversial topics among East Asian palaeobotanists (Golozoubov et al. 1999; Saiki & Wang 2003), with much disagreement about limits, degree of differentiation, assignment of some species to one or another zone, and the existence of oscillations of the palaeobiogeographical limits during the Mesozoic etc.…”

Although the faunal elements of Far East Asian Mesozoic terrestrial biota have attracted much attention in recent years, their palaeoecology remains poorly known. In particular, features of the palaeoclimate are highly controversial. To address this point we used the Mesozoic fossil wood Xenoxylon, a genus recognized as an indicator of wet temperate biotopes and which is common in the area during the Carnian–Maastrichtian interval. We re‐appraised bibliographic data and gathered new data for Xenoxylon in the Mesozoic of Far East Asia. This demonstrated that previous taxonomic approaches to the genus have been so far idiosyncratic. We examined the anatomical diversity of morphogenus Xenoxylon in Far East Asia and compared it to that of samples from Europe. This indicates that in an area centred on north‐eastern China, Xenoxylon reached a level of anatomical diversity unmatched elsewhere in the world. We hypothesize that this diversity witnesses the persistence of palaeoecological conditions particularly suitable for Xenoxylon and that a wet temperate climate prevailed over most of the area throughout the Carnian–Maastrichtian interval. It is in this setting that the famous Jehol Biota probably evolved.
