hypaethral

There are two stages to crux maifan stone ' s formation , the first stage is the forming stage of primary material , that is to say , the stage of mother rock formation , in this stage , the latter hypabyssal intrusive of crystallization fractionation and self - metamorphic process are an important factor to make sure them have many trace elements 麥飯石的形成中有兩個階段是十分關鍵的,第一個階段是基本物質的形成階段,即母巖的形成階段。在這一階段中巖漿分異結晶晚期的淺成侵入以及自變質作用,是保證其富含營養微量元素的重要條件。

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。

By physiognomy feature , it could be divided into three types of thermal structure : positive dome model , negative collapse model and border dome core collapse model . based on the depth degree or magma - thermal influenced , it could be divided into five types of thermal structure : ( ancient ) geothermal anomaly focus region model , superficial volcano eruption hydro - thermalism and hypabyssal intrusive model , thermal anticline ( thermal dome ) model , mid - deep intrusive model , deep mantle ( crust ) thermal plume model ; and put forward a perfect model of the thermal structure . there are many interaction system could be induced into a systematic thermal interaction , include : ocean - continent system , basin - mountain interaction , superficial and mid - deep crust - mantle interaction , crust - mantle commingle interaction , vertical thermal interaction ( delamination ) etc . 依據地貌形態分為三類:正向穹窿型、負向塌陷型、邊隆核陷型:依據巖漿-熱力作用影響的深淺程度或深度分為五類: (古)地熱異常群集區、表淺層火山噴發-熱液活動與淺成侵入型、熱力背斜(熱穹窿) 、中深層侵入型、深部地幔(地殼)熱柱型;提出了熱力構造作用空間分布的理想模式,將洋陸系統、盆山作用、淺表與中深部殼幔作用、殼幔混合、垂向熱力作用(拆沉)等納入一個整體統一的熱力作用系統中,為盆地動力學研究打開了一個新窗口;研討了熱力構造研究方法。

Research and analysis were carried out on yangshan super - large gold deposit in terms of regional background for tectonic evolution and development and geological and geochemical characteristics for metallogenesis , and the results indicate that it is a hydrothermal ( medium to low temperature type ) super - large gold deposit formed in mesozoic to cenozoic activated orogens or at hypabyssal positions in the crust 摘要從陽山超大型金礦床的區域構造演化發展背景、成礦地質地球化學等特征進行的研究與分析表明,它是形成、產出在中新生代活化造山帶、地殼高位淺成的中低溫熱液型超大型金礦床。

Through the study of the example of shaxi porphyry body in anhui province , the authors first figured out the storage time of plagioclase phenocrysts , then calculated the nucleation rate and growth rate of the crystals and , on such a basis , established the thermal model for cooling of the hypabyssal magmatic system 本文試圖通過對安徽沙溪斑巖體進行實例研究,先求出斜長石斑晶的存儲時間,再算得晶體成核速率和生長速率,進而建立起淺成巖漿體系冷卻的熱模型。
