Firstly, the volcanics and shaly sand were separated with FMI static images and conventional logging data. Then, the image characteristics of all typical volcanics were analyzed with the dynamic FMI images to establish the FMI image patterns of volcanic lava (including rhyolite, dacite, andesite, and basalt) and volcaniclastic rock (including volcanic breeds and tuff).
首先利用FMI静态图像和常规测井曲线将砂泥岩与火山岩区分开来；然后利用FMI动态图像分析了火山岩各种岩性的图像特征，归纳总结出火山熔岩类（流纹岩、英安岩、安山岩、玄武岩）和火山碎屑岩类的FMI图像模式。

In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.
元素地球化学特征表明，早三叠世火山岩具有典型的岛弧火山岩的特征，暗示其很可能形成于俯冲的构造环境；中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征，结合其流纹岩具有A型花岗岩属性，表明该区中三叠世火成岩形成于碰撞后的构造背景；而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损，但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征，说明这些火山岩可能形成于碰撞后裂谷环境。

The metamorphic rocks of the area consist of granulite, plagioclase-gneis, biotite leptite and various kinds of schists of granulite to amphibolite facies By reconstruction, this metamorphic series is composed of three original formations which inciude five originai rock types: intermediate-acid volcanics formation at the bottom basic-felsic bimodae volcanits formation in the middle and basic-andesitic-felsic volcanics formation at the top...
区内太古代变质岩系广泛发育，其下部为深变质的麻粒岩相地层，上部为中深变质的角闪岩相地层，后者产出红透山式铜锌矿床多处，以及张胡子沟铜矿床和大荒沟硫铁矿床等一系列块状硫化物矿床(图1)。矿石中铅同位素年令为25～26亿年，在形成时代上可以和鞍本地区鞍山群对比。
