This thesis studies each structural layer ' s feature : ( 1 ) structural layer of basement : it is a paleozoic folded basement, whose tectonic deformation and magma intrusion is fiercely, and it is affected by the early hercynian tectonic movement and related to the underthrust and closure ( c1 ) of zhungaer ocean basin and the areal pressing of continents ( c2 - 3 ) ; ( 2 ) structural layer of permian : due to the regional extending and fault depression role in mid - hercynian, it occurred to the combinations of structure and magma in santanghu basin and it ' s periphery area, such as a - granite ' s stock, batholiths and diabase ' s dike. there are many fault depressions possible
按照不同構造層，研究了各構造層的構造特徵：基底構造層：受早海西期構造作用的影響，與準噶爾洋盆俯沖閉合、而後陸-陸碰撞的區域擠壓構造作用有關，為一構造變形和巖漿侵入活動強烈的古生代褶皺基底。二疊系構造層：受中海西區域性伸展斷陷作用的影響，盆地及其周緣地區發育與伸展構造有關的構造-巖漿組合，如呈巖株、巖基狀侵位的a型花崗巖以及呈巖墻狀侵位的輝綠巖等。 -
And apatite. by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china, the characteristics of the granite in this area are concluded as follows. it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p. re congenetic ; the range of temperature is about 500 - 700, the range of pressure is about 2. 50 gpa - 4. 35 gpa, and the range of oxygen fugacity ( lg fo2 ) is - 15. 53 - - 14. 00 ; most granite bodies formed before the collision of plates, and few formed after the collision of plates
通過對測試數據的分析與綜合研究，並同中國和世界一般花崗巖類以及中國主要金、銅成礦巖體的花崗巖類進行對比，得出本區花崗巖類巖石具有以下特徵：屬磁鐵礦-型或同熔型花崗巖，其巖漿物質具殼幔混源特徵：主要由熔融態巖漿經結晶分異作用，通過多期變速上侵而形成；其分異演化程度較低；寄主巖基和包體具有同源性；巖石的形成溫度范圍約為500 - 700 ，壓力大約為2 . 50gpa - 4 . 35gpa ，氧逸度值1gfo _ 2為- 15 . 53 ? 14 . 00 ；該巖帶主要形成於板塊碰撞前消減的活動板塊邊緣期，為燕山至喜馬拉雅早期的大陸邊緣火山弧環境的產物。 -
In the area without magma mingling or with weak magma mingling, the host rock is dominated by porphyaceous adamellite showing normal granite fabric
無巖漿混合作用或巖漿混合作用較弱區段，寄主巖石以似斑狀二長花崗巖為主，顯示正常的花崗巖結構構造巖漿混合作用強烈區段。 -
Known as the devils marbles, these naturally rounded boulders formed over a billion years ago when cooling magma in the earth ' s crust forced up mounds of sandstone - covered granite
這些天然的圓形大石頭被稱為「魔鬼的彈珠」 ，大約在十億年前，地殼中冷卻的巖漿從砂石覆蓋的花崗巖石堆中湧出，形成了這些圓石。 -
In the late stage of mineralization occurred in the hercynian period, a widespread strong modification of ores or mineralized rocks of early stage caused by intrusion of parental magma of granite - porphyry leads to further enrichment of gold element and eventual formation of the gold deposit
第二期成礦作用是在海西構造運動中，由於花崗斑巖原始巖漿的侵入活動使早期的礦石或礦化巖石受到較強烈改造，使其中的金得到進一步富集，從而構成了現在的礦體。 -
At deeper levels, the volcanic deposits were intruded by molten magma, which slowly crystallised to form granite
在地殼較深處，熔化的巖漿侵入原先形成的火山巖，慢慢結晶成花崗巖。 -
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。
