近日,矿床学领域权威期刊《Economic Geology》刊发我校资源学院和GPMR国家重点实验室李建威教授团队和昆士兰大学放射性同位素实验室合作的研究成果——首次利用LA-(MC)-ICPMS方解石U-Pb测年法精确确定了卡林型金矿床的形成时代。这是该团队继卡林型金矿成矿流体来源与演化示踪研究“Noble gases fingerprint the source and evolution o...
Researchers have for the first time traced the roots of crabs, lobsters and shrimp to create the family tree of crustaceans people love to eat.The tree shows the 450-million-year evolution of these 10...
As a window of insight into the lower crust, high pressure granulite has received much attention since last decade. Yushugou high pressure granulite-peridotite Complex was located in the northeast mar...
The inert gas radioactive isotope 85Kr (with a half-life of 10.74 years), due to its stable physical and chemical properties, is an ideal tracer for shallow groundwater dating. In such a dating applic...
近日,中国地质大学资源学院和地质过程与矿产资源国家重点实验室李建威团队有关青藏高原东缘玉龙超大型斑岩铜矿床风化壳(U-Th)/He年代学的研究成果发表在地学领域重要综合期刊《Earth and Planetary Science Letters》上。该文第一作者为地质过程与矿产资源国家重点实验室邓晓东研究员,通讯作者为资源学院李建威教授。
The large, fast-moving mudslide that buried much of Oso, Washington in March 2014 was the deadliest landslide in U.S. history. Since then it’s been revealed that this area has experienced major slides...
In Cornell’s “CS4830: Introduction to Cryptography” offered Fall 2015, students are asked to devise a physical secure two-party protocol for computing AND, using 4 cards or fewer. An elegant 5-card ...
Lichenometry is a surface-exposure-dating procedure that complements traditional trench-and-date stratigraphic studies of earthquakes. Lichens on the surficial blocks of a slump in the Seaward Kaikour...
A first paleomagnetic investigation aimed at constraining the age of the non-sulfide Zn-Pb ore deposits in the Iglesiente district (SW Sardinia, Italy) was carried out. In these ores, the oxidation o...
The Roveto Valley is a narrow, elongated, NW-trending depression filled with continental Plio-Quaternary deposits that outcrop at different topographic elevations. A morpho-lithostratigraphic successi...
Are women who have been the victim of psychological abuse in the past more likely to prefer an abusive dating partner in the future? Are men who have been the perpetrator of abuse more likely to pr...
The study was conducted to determine the desirability or otherwise of mathematically correcting every normal foetal head shape to an ideal shape prior to dating using the biparietal diameter (BPD). Tr...
The large literature on costly signaling and the somewhat scant literature on preference signaling had varying success in showing that sending a signal affects outcomes. We use a field experiment to s...
We examined whether it is possible to relate concentrations of trace elements in alluvial sediments with records concerning the intensity of mining, and use them as a means of dating. We conducted our...
