【正文】 Powder sandstone layer in the development of ocean shell characteristics of double hull (Halobia) and trace fossils plateau roaming trace fossils ((Plno litesm ontanus), typical deepwater turbidite facies characteristics. The above facts show that widely distributed in the mining area of fine clastic rock formation is a set of turbidite rock formed in the deep sea environment construction. The strata rock microelement statistical results as follows: cataclastic rock gold up to 5 x109, variation coefficient of 210%。 The latter39。區(qū)域高的熱流值是擠壓造山帶的重要特征。 溫度是使金由穩(wěn)定狀態(tài)轉(zhuǎn)化為活動(dòng)狀態(tài)的重要因素。以上事實(shí)表明，廣泛分布于礦區(qū)的細(xì)碎屑巖建造是一套形成于深海環(huán)境的濁積巖建造。含黃鐵礦、方鉛礦、具孔雀石化的石英脈 Pb一 Pb法測(cè)得成礦年齡為 187Ma，屬燕山早期，可見(jiàn)其成礦時(shí)代為印支晚期燕山早期，與區(qū)域造山運(yùn)動(dòng)基本吻合。礦石金 品位最高 110g/t，最低 ，一般 2~9g/t，平均 5. 76g/t，通過(guò)對(duì)礦區(qū) 24 條礦體資源量估算，共獲得 333+334 金資源量 81. 4 噸，達(dá)大型規(guī)模。斷裂構(gòu)造多沿背斜軸部產(chǎn)生。礦區(qū)熱液蝕變發(fā)育，其規(guī)模和強(qiáng)度決定于構(gòu)造破碎帶規(guī)模、性質(zhì)和巖石能干性。 礦床圍巖和礦石中的黃鐵礦單礦物的δ 34S值介于一 %0 %0之間，平均一 4. 97 %0，數(shù)值變化范圍小，顯示地層硫來(lái)源。 上述信息表明，大場(chǎng)金礦的成礦元素 、硫和脈石組分主要來(lái)自地層，成礦溶液為大氣降水形成的深層地下水。 該套地層巖石微量元素統(tǒng)計(jì)結(jié)果為 :碎裂巖含金最高為 ，變化系數(shù) 210%。一般來(lái)講，溫度升高，金的溶解 度也隨之增大。 巖漿熱和構(gòu)造熱的結(jié)合，使得大場(chǎng)地區(qū)成為一地?zé)岙惓^(qū)，并具有較高的古地溫梯 度區(qū)內(nèi)構(gòu)造破碎帶發(fā)育的鈣化就是地?zé)岙惓５淖糇C . 大場(chǎng)微細(xì)粒浸染型金礦與斷裂破碎帶形影相依。s uniform temperature has two peaks: one is 232 ℃ , 275 ℃ and salinity a 9. 47 WTD/mNaCI, 2 it is 149 ℃ , 229 ℃ , salinity of a WTD/m NaCI. Immiscible function of fluid occurred in 236 ℃ 236 ℃ , the fluid does not mix solution of CO2 H20 fluid was isolated and NaCl H20 fluid is the main oreforming fluid of gold.
