全球各大科学网站,几乎每天都有天文学新研究成果发布.就让我们来看一看最近一些引起关注的天文学新发现.rn嫦娥5号带回月球样本揭示月球岩石年龄rn由中国发射的嫦娥5号月球探测器,最近把一些新的月球岩石和土壤样本带回了地球.这是过去40年来探测器首次把月球样本带回地球.根据这些新样本,一个国际研究团队已经确定这些月球岩石的年龄接近19.7亿年.科学家认为,嫦娥5号带回的样本填补了10亿年的空白.此话怎讲?

The northern margin of the North China Craton (NCC) contains widespread Permian magmatic rocks,but the origin of these rocks remains controversial.This uncertainty hampers us from better understanding of tectonic framework and evolution of the eastern Pal
Tourmaline geochemical and boron (B) isotopic compositions in two-mica granites (TMG),tourmaline-bearing leucogranites (Tou-LG),tourmalites and metapelites from the Gyirong-Malashan areas of the Himalayan orogen provide evidence for country rock assimilat
有人说,天堂般的香格里拉是中华大地上最令人向往的地方之一.但深入滇西北,你会发现一片与香格里拉同样接近天空的净土——维西.这里地处世界自然遗产“三江并流”腹地,素有“横断山脉中的绿宝石”的美称.这里屹立着积雪终年不化的白马雪山,有仙境一般的原始森林.维西人烟稀少,自古只有一条人马驿道通向外界.维西是陶渊明笔下的“世外桃源”,也是滇西北野生动物的生命之舟.生活在这里的人们,世世代代齐心守护着滇金丝猴.

Shallow carbonate deposits (Tarbur Formation) were formed in the Zagros foreland basin with dynamic tectonics during the Maastrichtian age.From the viewpoint of reconstruction of depositional conditions in these deposits,studies of biostratigraphy,microfa
The Sichuan Basin,also known as the \'Red Basin\',is famous for its abundance of Mesozoic dinosaur fossils,especially in the Zigong area during the Jurassic era;the Middle Jurassic Shunosaurus and the Late Jurassic Mamenchisaurus faunal assemblages ar
In order to understand how the metallogenic process of porphyry deposit specifically and directly respond to regional uplifting and exhumation,we compiled previous fluid inclusion data of 32 porphyry deposits in China by recalculating the fluid trapping d
Deep mineral exploration is increasingly important for finding new mineral resources but there are many uncertainties.Understanding the factors controlling the localization of mineralization at depth can reduce the risk in deep mineral exploration.One of
The distribution of selected critical elements in the sedimentary rocks of the Carboniferous coal-bearing series within the Polish Coal Basins is presented.Critical elements such as Be,Mg,Si,P,Sc,V,Co,Y,Nb,In,Sb,La,Ce,Hf,Ta,W,Bi were analysed using induct
The Neoproterozoic banded iron formations (BIFs) were closely associated with the “Snowball Earth” during the breakup of the Rodinia,thus they played an important role in our understanding of the atmospheric and oceanic oxygen levels during this period.In
The precipitation of authigenic quartz plays a significant role to reduce the reservoir characteristics and enhance the stiffness of the rock.The Es1 sandstone of Shahejie Formation is acting as a significant hydrocarbon producing rock in the Nanpu Sag.Va
