The subeconomic Mount Novit Zn-Pb-Ag deposit is located approximately 20 km south of Mount Isa,Queensland.In contrast to the nearby Mount Isa,Hilton and George Fisher Zn-Pb-Ag deposits,minerali-sation at Mount Novit is situated to the west of the regional
Hydrous minerals within the subducting oceanic slab are important hosts for water.Clarification of the stability field of hydrous minerals helps to understand transport and distribution of water from the sur-face to the Earth\'s interior.We investigated
Rapid industrialization and urbanization along with a growing population are contributing significantly to air pollution in China.Evaluation of long-term aerosol optical depth(AOD)data from models and reanalysis,can greatly promote understanding of spatio
The mechanism of slope failure associated with overpressure that is caused by hydrocarbon migration and accumulation remains unclear.High-resolution seismic data and gas hydrate drilling data collected from the Shenhu gas hydrate field(site SH5)offer a va
The Early Cretaceous-Early Eocene granitoids in the Tengchong Block record the evolutionary history of the Mesozoic-Cenozoic tectono-magmatic evolution of Eastern Tethys.(a)The Early Cretaceous grani-toids with relatively low(87Sr/86Sr)i ratios of 0.7090-
Continental Flood Basalts(CFB)occupy one fourth of the world\'s land area.Hence,it is important to dis-cern the hydrological processes in this complex hydrogeological setup for the sustainable water resources development.A model assisted isotope,geochem
A garnet-bearing schist from the southernmost such exposure along the Himalaya in east central Nepal records prograde metamorphism at 32.4±0.3 Ma.Phase equilibria modelling,combined with Ti-in-biotite and quartz c-axis thermometry,outline a tight-to-hairp
This study presents a re-examination of historical specimens(DG136 and DG167)from the Monashee complex in the southeastern Canadian Cordillera that are critical to the current understanding of rare earth element(REE)distribution between garnet and monazit
任何有通过放大镜逮虱子体验的人都知道,雌性头虱用于把虱卵黏附在人类毛发上的黏合剂是多么有效.一旦虱卵粘在了毛发上,想把它们弄下来就很困难.科学家曾经发现,哪怕过了 1万年,虱卵仍然死死贴在古人的毛发上.rn虱子版《侏罗纪公园》rn有科学家2022年1月宣布,他们通过研究发现了虱子的黏合剂——虱胶的不凡之处.他们发现,虱胶竟然能完好保存它所包裹的任何生物材料,其中包括虱子的人类宿主的DNA.这项研究令人想起著名科幻影片《侏罗纪公园》中的情节.在该影片中,吸食恐龙血液的蚊子后来被封闭在琥珀中,科学家从这些蚊子
