【導(dǎo)讀】南坡斷裂為界與阿尼瑪卿縫合帶毗鄰。前人將大場(chǎng)金礦的金礦化類型定為造山型金礦床，我。北金牙金礦等類比，金礦化類型為微細(xì)粒浸染型金礦.板巖夾灰色長(zhǎng)石砂巖。金礦體在平面上嚴(yán)格受斷裂構(gòu)造破碎帶控制，因而容礦巖石普遍具不。同程度的破碎變形，直至部分成為碎裂巖。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。礦石礦物主要為黃鐵礦和毒砂，脈石礦物主要為石英、方解石，載金礦物主要為熱。液黃鐵礦和毒砂，金呈分散狀態(tài)賦存在兩礦物的晶粒內(nèi)，無(wú)明顯的集中分布區(qū)。于Hg,As異常之內(nèi)，具低溫元素組合特征。量估算，共獲得333+334金資源量81.4噸，達(dá)大型規(guī)模。前者形成于236℃一315℃、低鹽度。()、富含CO2、有少量CH4和(或)N2組分集中于℃一℃之間，形成于深海環(huán)境的濁積巖建造。濁積巖中普遍含有機(jī)碳的成分，在沉積過(guò)程。含金地質(zhì)建造的濁積巖。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。
【正文】 loped, eastern outcropped indosinian yanshanian granite, they are after the invasion of the thermal effect produced by a long time, inevitably lead to the emergence of a certain line heating anomaly. Large field of microgranular disseminated type gold deposit is a reflection of the lowtemperature mineralized contact some space and dike rock mass, is actually a reflection of this hot field. Structure: large tectonic environment field gold mining area is located in the north BaYanKaLa indosinian orogenic belt, in the north, nima qing was born with suture zone in late Paleozoic early in the morning, since the late indosinian, regional strong pressive state for a long time. Extrusion effect in rock layer is fold deformation, in the process of rock breaking and displacement, kiic energy is converted into heat energy, a large number of structure movement between rock frictional heat can even reach the level of melt rock. Regional high heat flow value is an important characteristic of extrusion of orogenic belts. Magma heat and heat is the bination of structural, making large area bee a geothermal anomaly area, and has high degree of palaeogeothermal ladder tectonic fracture zone in the area of calcification is geothermal anomaly evidence. the fracture system of form a plete set is ore fluid migration and mineralization locate space. Large field and fractured zone of the microgranular disseminated deposits around together. Ore fracture for deep fault that more than a gander side of deep fault that with basic secondary 6 fracture distribution is parallel, mineralization mainly occurred in the pression shear fracture properties into extensional expansion area. Because of metallogenic enrichment coefficient of the required and to gather the oreforming elements in the big scope, it must have a deep cut fracture exists, to make munication and deep and form massive hydrothermal circulation system, this is the mineralization associated with major fault with time and space. Side of secondary pression shear fracture, can cause good shielding conditions and semiclosed environment, temperature, pressure drop is slow, is advantageous to the metasomatism of thorough and high sulfur and low oxygen and the formation of mineral ore body in extensional space positioning. To sum up, the Triassic turbidite rock formed by the deposition of construction, is a kind of gold bearing geological formation, mainly in the form of adsorption exists in most of the gold to be released (active) gold, lay the ground for mineralization.
