Discovered　several　gneiss　tonalité　bodies　on　the　southwestern　margin　of　the　Tarim　basin　have　been　reported　in　the　paper.　They　are　possessed　of　higher　Si,　Al,　Na;　enriched　in　LREE　,　LILE　and　Zr,　Hf,　Ti　of　HFSE　,　depleted　HREE　and　P,　Ni,　Cr　of　HFSE,　and　possessed　of　A-type　granite　features　in　geochemistry.　Zircon　SHRIMP　U-Pb　dataing　showed　that　there　are　three　group　age:　the　first　group　age　is　(1970±47)　Ma　(n　=　4,　MSWD=2-　4)　which　recorded　succeeding　zircon　age　of　magma　seizured;　the　second　group　age　is　(764±33)　Ma　(n　=　4,　MSWD　=　2.　50)　which　represented　intruding　age　of　gneiss　granite;　the　third　group　age　is　(424±16)　Ma　(n　=　6,　MSWD=　1.　03)　which　implied　age　of　Caledonnian　tectonic　event.　It　maybe　provided　a　record　of　magma　function　brokenup　Paleo-continent　of　Neo-Proterozoic　in　the　Tarim　Basin,　it　provides　an　important　basis　for　the　stratigraphie　division　in　this　district　and　an　important　information　of　the　geological　tectonic　evolution　.
