摘要: Abstract Isotopic (Sr and Nd) mineralogical analyses of dust extracted from snow deposits the last decade at NorthGRIP, Greenland, ice camp (75.1°N, 042.3°W) confirm eastern Asian source for Greenland extend it to present day. The 1998 1999 samples, which represent a ∼2.4 month resolution deposition, show that there are least two east sources vary seasonally. provenance during major, spring/summer deposition is Takla Makan desert northwest China.
