-
The copper, iron, nickel and silver deposits might be assigned to four metallogenic series : i. the metallogenic subseries of copper, molybdenum, gold, silver deposit related to late devonian - early carboniferous basic - intermediate - acid hypabyssal intrusive - eruptive rocks ; ii. the metallogenic subseriesof iron, copper, zinc deposits related to early carboniferous basic - intermediate - acid volcanic - intrusive rocks ; iii. the metallogenic subseries of copper, silver, iron deposits related to middle - late carboniferous basic - intermediate - acid volcanic - intrusive rocks ; iv. the metallogenic subseries of copper, nickel and platinum group deposits related to late carboniferous - early permian basic - ultrabasic rocks ; 3, division of regional major metallogenic belts on the basis of the previous work conducted and by following the principles, grounds and methods of the division of metallogenic belts, areas and fields, . in light of this, metallogenic belts of grade iv were divided
1 、按照成礦系列理論的學術指導思想，將研究區華里西期銅礦床成礦系列劃分為四個成礦系列亞系列： 、晚泥盆?早石炭世延東?土屋?三岔口與中酸性巖漿侵入活動有關的cu 、 mo 、 au礦床成礦亞系列、早石炭世與巖漿作用有關的鐵、銅、金、銀礦床成礦亞系列、中石炭世與巖漿作用有關的cu 、 fe 、 ag 、 au礦床成礦亞系列、晚石炭世-早二疊世與幔源基性?超基性巖有關的銅、鎳、鉑族礦床成礦亞系列並從地層、巖漿巖、控礦構造、地球化學、成礦特徵等方面對各成礦亞系列進行了詳細論述。 -
The ultrabasic rocks form a complex of large tectonic slices with intercalated slices of sebakwian sedimentary rocks.

The coqen basin in xizang lies between the bangong - nujiang suture zone and yarlung zangbo suture zone, and once extended northwards and southwards, respectively centred by the qiekan - goicang - asog rift zone as the center of deposition and subsidence during the middle jurassic to the early creatceous. ( 1 ) during the middle - late jurassic, the rift zone was occupied by deep - water turbidites, radiolarian siliceous rocks, shallow - water carbonate rocks, clastic rocks and basic - ultrabasic rocks, while both sides of it by littoral and shallow marine elastic rocks and carbonate rocks
