“…Then, Kelly et al (1994) indicated that the original ammonite specimens reported from the Qihulin Formtion are mainly desmoceratids with subordinate tetragonitids, whereas Futakami et al (1995) described the ammonites as a Barremian Pseudohaploceras fauna. Thus, the Jixi and Longzhaogou groups were reassigned to an Early Cretaceous age (Sha et al, 1994;Gu et al, 1997;Sha et al, 2002).…”

A comparative analysis of Late Jurassic-Early Cretaceous strata have been done for the SanjiangMiddle Amur basin, a coal-and oil-bearing area spanning the eastern Heilongjiang of northeastern China and southeastern Far East of Russia. On the basis of various fossils occurring in the formations, particularly by means of the Tithonian-Valanginian indexBuchia and the late Barremian-middle Albian indicator Aucellina assemblages, the marine and non-marine Late Jurassic-Early Cretaceous strata in the basin are correlated. The Mesozoic international chronostratigraphic chart (http://www.stratigraphy.org) is established basically based on the marine rocks. To accurately date the non-marine strata, it is necessary to correlate them with the marine deposits. This study sheds new light on the dating and correlation of non-marine Upper Mesozoic. Additionally, the results would help understand the tectonics and paleogeography and thus aid the exploration of energy resources. Upper Jurassic-Lower Cretaceous, marine and non-marine, correlation, Sangjiang-Middle Amur basinThe Sanjiang (Heilong (Amur) River, Songhua (Sungari) River, Wusuli (Ussuri) River; Jiang means river in Chinese)-Middle Amur (Heilong) sedimentary basin situated on the northwestern coast of Paleo-Pacific during the Late Mesozoic presently spans the boundary of Russia-China. Its southwestern part is situated in eastern Heilongjiang, northeastern China and the northeastern part in southeastern Far East of Russia (Figure 1). This basin contains Late Mesozoic marine and alternating marine and non-marine deposits, commonly associated with volcanic rocks, and yielding abundant coal and even oil [1][2][3][4][5][6][7][8][9][10] . In the basin there exist the Jurassic-Cretaceous boundary [9,[11][12][13] and the mixed boreal and Tethyan fauna recording the paleocurrent events [14][15][16][17] , recordings of the transgressions along the Tan (Tancheng)-Lu (Lujiang) fault system [10,18] .Consequently, Sangjiang-Middle Amur basin is a unique area for the study of the Late Mesozoic paleontology, stratigraphy, paleogeography, tectonics, and energy resources. Although much has been published on paleontology, sedimentology, stratigraphy, paleogeography (including the transgression and paleocurrents), and tectonics of the basin, most of them are concentrated on either the Chinese part or the Russian part without correlations between them. Four UNES-COIUGS IGCP Projects (350, 434, 506, 507) and a joint Russian-Chinese project [1,18] made it possible to examine the boundary structure and the evolution of the basin. Even though the Jurassic-Cretaceous boundary of the basin was globally discussed [11] , the correlation between

A suite of hornblendite (amphibole proportion C90%) enclaves were found in Late Cretaceous dioriteporphyrite stocks intruding the lower Cretaceous coal strata around the Shuangyashan City, eastern Heilongjiang Province, Northeast China. The enclaves have similar mineralogy and may be divided into clinopyroxene-bearing and clinopyroxene-free hornblendites and both of them show cumulate textures: pargasitic amphibole and clinopyroxene are cumulus and anorthitic plagioclase is intercumulus. The accumulation might have occurred in the magma chamber, minor clinopyroxene enclosed in amphibole was earlier crystallized, followed by a large amount of amphibole, and the residual melt trapped between cumulate crystals finally formed the intercumulus plagioclase. Probably, such a crystallization process could produce layered cumulates: lower part is dominated by clinopyroxene-bearing hornblendite and upper part is composed of clinopyroxene-free one. The enclaves have similar geochemistry and imply a hydrous basaltic parental magma enriched Rb, Ba, Th and other large-ion lithophile elements. The generation of the parental magma might be related to the subduction of Paleo-Pacific plate beneath eastern Eurasian continent at that time. Estimated crystallization pressure, P-wave velocity, and density for the cumulate hornblendite enclaves are generally in agreement with the values of the local crust-mantle transition zone, suggesting that these cumulates may have the origin in the transition from the lower crust to upper mantle in arc and back-arc settings.
