塔里木盆地火成岩对碳酸盐岩储层的改造作用

塔里木盆地形成与演化过程中出现过多期的岩浆侵入与喷发活动,形成了多种类型的火成岩体.岩浆活动形成的火成岩带来了地壳深部的热液流体,其中富含二氧化碳、硫化氢、硫、及少量一氧化碳、氢、HCl、NH3、NH4Cl、HF等的酸性流体对上部碳酸盐岩储层产生了多种多样的改造作用,包括大理岩化作用、萤石化作用、热液白云岩化作用、热液溶蚀作用等.多种改造作用的结果,使得原本致密的碳酸盐岩储层,形成了大量各种类型的孔洞,孔隙度大大增加,储集性能得到改善.勘探过程中,火成岩的出现可以预示附近地区良好储层的发育,为勘探油气起到了示踪作用.     

月球Aristarchus地区的物质成分与岩石类型分布

月球Aristarchus地区是月球正面反照率最高的地区．它具有丰富的物质类型分布,包括月球最大规模的火成碎屑沉积物,非常年轻的Aristarchus撞击坑溅射物以及环绕Aristarchus高原的月海玄武岩分布,存在火山、撞击构造等地质作用,具有重要研究价值．本文利用来自嫦娥一号干涉成像光谱仪、ClementineUVVIS相机、LunarProspector伽马谱仪等月球探测数据,综合分析Aristarchus地区的元素分布状况、矿物与岩石光谱特征、岩石类型分布特征．研究表明,Aristarchus地区的光谱特征和物质类型极为丰富,包括火成碎屑沉积物、月海玄武岩、高地斜长岩、KREEP岩以及演化程度较高的碱性斜长岩等特殊岩石类型,为月球地质学研究中不可多得的案例区域,因而可作为我国探月工程三期（嫦娥五号或六号）月球取样返回候选地区之一．

Late formation and prolonged differentiation of the Moon inferred from W isotopes in lunar metals

The Moon is thought to have formed from debris ejected by a giant impact with the early 'proto'-Earth and, as a result of the high energies involved, the Moon would have melted to form a magma ocean. The timescales for formation and solidification of the Moon can be quantified by using 182Hf-182W and 146Sm-142Nd chronometry, but these methods have yielded contradicting results. In earlier studies, 182W anomalies in lunar rocks were attributed to decay of 182Hf within the lunar mantle and were used to infer that the Moon solidified within the first approximately 60 million years of the Solar System. However, the dominant 182W component in most lunar rocks reflects cosmogenic production mainly by neutron capture of 181Ta during cosmic-ray exposure of the lunar surface, compromising a reliable interpretation in terms of 182Hf-182W chronometry. Here we present tungsten isotope data for lunar metals that do not contain any measurable Ta-derived 182W. All metals have identical 182W/184W ratios, indicating that the lunar magma ocean did not crystallize within the first approximately 60 Myr of the Solar System, which is no longer inconsistent with Sm-Nd chronometry. Our new data reveal that the lunar and terrestrial mantles have identical 182W/184W. This, in conjunction with 147Sm-143Nd ages for the oldest lunar rocks, constrains the age of the Moon and Earth to Myr after formation of the Solar System. The identical 182W/184W ratios of the lunar and terrestrial mantles require either that the Moon is derived mainly from terrestrial material or that tungsten isotopes in the Moon and Earth's mantle equilibrated in the aftermath of the giant impact, as has been proposed to account for identical oxygen isotope compositions of the Earth and Moon.

Global inventory of Helium-3 in lunar regoliths estimated by a multi-channel microwave radiometer on the Chang-E 1 lunar satellite

Helium-3 (³He) implanted by solar wind in the lunar regolith is a valuable resource because of its potential as a fusion fuel. On the basis of the Apollo regolith samples, a linear relationship between ³He abundance and solar wind flux, optical maturity and TiO₂ content has been presented. China successfully launched its first lunar exploration satellite Chang-E 1 (CE-1) on October 24, 2007. A multi-channeled microwave radiometer was aboard the satellite with the purpose of measuring microwave thermal emission from the lunar surface layer. From the multi-channel brightness temperature (T_b) observed by CE-1, the global distribution of the regolith thickness was inverted from the multi-channel T_b, and was used to evaluate the total amount of ³He per unit area in the lunar regolith. The global inventory of ³He was estimated as being 6.6×10⁸ kg; 3.7×10⁸ kg for the lunar nearside and 2.9×10⁸ kg for the lunar farside.

Close tetrapod relationships of the coelacanth Latimeria indicated by haemoglobin sequences

The origin of tetrapods has been debated for many years. In traditional systematics, the extinct lobe-finned bony fish (Rhipidistia) are regarded as the closest relatives of tetrapods. Among living fish, the coelacanth Latimeria chalumnae (Actinistia), which is the only recent representative of the Crossopterygii (Actinistia and Rhipidistia), the lungfish (Dipnoi) and ray-finned fish (Actinopterygii), have each been considered as sister-groups of the tetrapods. We have now determined the sequence of the alpha- and beta-globin chains of coelacanth haemoglobin and compared them with all known haemoglobins of bony and cartilaginous fish as well as those of tadpoles and adult amphibians. Haemoglobins of bony fish match more closely those of larval than adult amphibians. The beta chains of Latimeria match those of tadpoles more closely (54%) than do those of any other fish, whereas the alpha chains of Latimeria (45.4%), and especially of teleosts (49.2%), are closer to those of larval amphibians than are those of lungfish (39.8%). If only synapomorphous sequence matches (those at derived positions shared by one bony fish and tadpoles but not by any other bony fish) are considered, both Latimeria globin chains have distinctly more identities with phase of tadpoles than do those of any bony fish. Thus the primary structure of Latimeria haemoglobin indicates that the coelacanth is the closest living relative of tetrapods.     

中秋月饼考

关于中秋月饼产生的时间和原因，有多种说法。经过文献考证可知，中国饼食的制作有古远的历史，而月饼的前身是汉代以来的胡饼。关于中秋月饼产生于唐代和宋代的说法都是没有确凿依据的。有充分资料证明，作为中秋节节令食品的月饼正式出现于明代，开始它是拜月的供品，后来才演变为节令食品。     

Optical detection of meteoroidal impacts on the Moon

Impacts of meteoroids on the Moon should cause detectable optical flashes, but the population of objects that are big enough is very low, and hitherto no unambiguous impact flashes have been recorded. The flux of meteoroids associated with the Leonid meteor shower of 18 November 1999 was predicted to produce observable flashes on the night side of the Moon. Here we report the unambiguous detection of five such impact flashes, three of which were seen simultaneously by other observers. We also observed a possible impact flash on 16 July 1999. All of the flashes were of very brief duration (<0.02 s), as expected for high-speed impacts.
