  1. K - ar age of an illite from alteration rock in the contact zone around lianhuashan porphyry is 38. 6ma. with referencing to the main metallogenic period of yulong copper metallogenic zone and of ailaoshan gold metallogenic zone, it is suggested that the time of formation of deposits in the district studied is probably in a period of time from 38. 6ma at earliest to 20ma at latest. this time is equivalent to the origination time of two important tectonic events, i. e., lanping movement and the turning point when ailaoshan - red river fault turned from sinisteral into dextral

    獲得了蓮花山巖體周圍接觸帶蝕變巖中伊利石k - ar年齡38 . 6ma ,參考玉龍銅礦帶和哀牢山金礦帶的主要成礦期(分別為30ma左右及26ma ) ,釐定本礦集區成礦年齡下限為38 . 6ma ,上限為20ma ,與兩次重要的構造事件?蘭坪運動的起始時間及哀牢山?紅河斷裂由左旋轉為右旋的時間相當。
  2. And the generalized homothetic composite action of metallogenic subsystems mentioned above formed the multiple - composite metallogenic system of the jiangda tectonic belt. the typical ore deposits of jiangda tectonic belt, such as dingqinnong, jiaduoling, renda etc, are contact metasomatic type deposits formed intracontinental rifting stage, and the tectonic - magmatic - hydrotherm of intracontinental orogenic stage superposed and rebuilt some preexistent ore body. their space distribution is controlled by composite intrusive rock belt of ne direction

    對丁欽弄、加多嶺、仁達等典型礦床的研究表明,它們均為形成於陸內裂谷作用階段的接觸交代型礦床,陸內造山期的構造?巖漿?熱液作用疊加改造了先成礦體,礦床空間分佈受北東向復合侵入巖帶控制。
  3. The basin has three evolutionary stages including intracontinental rift basin in p1 - p2, down basin in t2 + 3 - k and the strong trust - orogeny process in n - q. according to the unconformity contact relationship and sedimentary components, santanghu basin is divided into four tectonic sequence such as : o - c tectonic sequence of basement, pi - p3 tectonic sequence, t - k tectonic sequence and n - q tectonic sequence

    根據盆地地層之間的不整合接觸關系,考慮到各層序沉積物組成與生物組合特徵等因素,將三塘湖盆地劃分為: ( o ? c )基底構造層序,二疊系( p )構造層序,三疊系( t ) ?白堊系( k )構造層序和第三系、第四系構造層序。
  4. The stratums containing mine, tectonic - hydro thermally process, magma activity, alteration react to district mineralization in degrees. the belt of granite facies, the inside and outside contact belt of rock body, the joining belt of tectonic - hydro thermally superimposed, the stratum belt of unconformity contact are the main enrichment belt

    含礦地層及礦源層、構造-熱液作用、巖漿活動、變質作用都在不同程度上對區域成礦起作用,而花崗巖相變化帶、巖體內外接觸帶、構造?熱液疊加交匯帶、地層不整合接觸帶則為金礦化主要富集帶。
