1.The Nymphaeales were consistently identified by recent molecular phylogenetic analyses as one of the three earliest lineages of angiosperms (the ANITA clades: Amborellaceae, Nymphaeales, Illiciales, Trimeniaceae, and Austrobaileyaceae), which, together with the new record of fossils of water lily flowers from the Early Cretaceous, support the long-held view that the Nymphaeales represent a primitive taxon.
2.In the sedimentary history, algae started to grow earlier in site L2 than in site L1, but the sediment in site L1 could fix more nutrients.
3.characterized by or characteristic of exceptionally early development or maturity (especially in mental aptitude).
4.The Baikal depression is the earlist and the largest undewater depression of the Baikal rift system,where occurred notable neotectonic activities with an vertical movement from southwest to north east.
5.In mice, for instance, delivery of melatonin increases the risk of tumor development, and the overproduction of growth hormone leads to kidney problems, premature heart and lung failure, and an increased probability of early death.
6.b. Key time of oil-gas migration and accumulation in northern margin of Qaidam Basin is Later Eogene and Middle Neogene, the important structural factors that controlled oil-gas migration and accumulation are the paleouplift developed in Yanshanian period and structural belts developed in Eogene;
7.The structure growth history of Lenghu 5 in Mesozoic and Cenozoic eras can be divided into five stages which are early Jurassic epoch extension rift stage, late Yanshan imbricate thrust stage, early period of Paleogene contemporaneous reverse faults growth stage,from late period of Paleogene to middle period of Neogene anticline growth stage and from late period of Neogene to Quaternary the anticline reformed stage.
8.Owing to its Cenozoic tectonic migration from west to east and from south to west, it developed three types of play, one is the lower early break-early decline play in the Huimin sag, the second is the middle inheritable play in the Dongying sag, the third is the upper late break-late decline play in the Zhanhua and Chezhen sags.
9.The granite related copper molybdenum deposits were formed in Early to Middle Jurassic transitional period from compression to extension, whereas W Sn Pb Zn Sb Hg Au Ag U mineralization took place in Late Jurassic and Early to Middle Cretaceous, corresponding to the period of large scale delamination of the lithosphere.
10.Bonan sag is a secondary negative structural unit in Jiyang depression. Structural evolution of the sag can be divided into four developing stages, i.e. thrusting structure stage of Triassic, negative inversion stage of latter Jurassic to early Eocene, faulted basin stage of middle Eocene, and depression basin stage from Miocene. The faulted basin stage is the most important forming stage of reservoir rock and source rock in the sag.
