The conclusion is that the enrichment of pt , pd is controlled by big and deep fractures , that emeishan basalt is one of the sources of pt and pd , and that basic - ultrabasic rock offers the ore - forming elements and the ore forming energy 指出研究區的深大斷裂對鉑族元素的富集表現出很好的控制作用,峨眉山玄武巖為鉑族元素的礦源層之一,巖漿巖為鉑族元素的富集提供了成礦物質及成礦能量。
A comparison of the prospecting model of the hf type with the prediction model of the vms type reveals that their thermal dynamic mechanisms are different : the former is related to basic - ultrabasic rock intrusion , while the latter to acidic rock intrusion 與白銀銅礦區域地球化學預測模式相比較,富鐵型鉛鋅礦床中除鐵族元素指示基性超基性巖侵入事件外,其他元素均大致相似,兩大類礦床形成的初始熱動力條件不同。
In this article , model of geological conception in panzhihua - xichang area is established , and then the authors used gis as the tool to analyze the pge ore - forming geological conditions , including geological structure , emeishan basalt , basic - ultrabasic rock and pge geochemical abnormal 本文在建立攀西地區鉑族元素礦床地質概念模型的基礎上,用地理信息系統( gis )分析了該地區的鉑族元素成礦地質條件,包括地質構造、峨眉山玄武巖、基性一超基性巖和鉑族元素地球化學異常特徵。
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 摘要位于班公湖怒江縫合帶與雅魯藏布江縫合帶之間的措勤盆地,在中侏羅世早白堊世期間具有以且坎古昌阿索裂谷帶為沉積、沉降中心向南北兩側展開的古地理格局:中晚侏羅世時期,裂谷帶內由深水濁積巖、放射蟲硅質巖和淺水碳酸鹽巖、碎屑巖巖片及基性超基性巖等組成;裂谷帶兩側由濱淺海相碎屑巖和碳酸鹽巖組成。
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并從地層、巖漿巖、控礦構造、地球化學、成礦特征等方面對各成礦亞系列進行了詳細論述。
