云南富宁安那金矿控矿因素分析

安那金矿赋存于中泥盆统坡折落组硅质岩夹薄层状灰岩中。东西向安那不对称褶皱构造是主要控岩控矿构造,次级北东向断裂和层间断裂是矿区的储（容）矿构造;矿区的金矿化与基性岩浆活动关系密切。

辽宁四道沟金矿地球化学基本特征研究

四道沟金矿床的矿脉群规模较大且复杂，单个矿体较零碎，连续性不好。各矿体及矿化体的成晕相互干扰较大。通过对典型矿脉群中的矿体、蚀变带、围岩及构造带、预测点系统取样分析，据热液成矿成晕原理对矿区基本地球化学参数进行了多元统计分析的若干方法处理得出并分析了元素组合规律；确定了成矿指示元素并解释了指示元素的地质地球化学意义；总结了矿脉群中矿体原生晕中元素的轴向组合分带序列。     

Discovery of an outcropping Mass Transport Deposit (MTD) in the Palaeogene subalpine synclines of southeastern France: Implications on flexural sub-basin deformation

We document the sedimentary facies of a large Mass Transport Deposit (MTD) within the sand-rich sediment gravity flow-dominated deposits of the Eocene–Oligocene south-western Alpine forelands (Annot Sandstone system). The MTD with an approximated volume of several hundreds of cubic kilometres fills a sub-basin located in the Mont-Tournairet confined sub-basin. Autochthonous facies are very typical sediment gravity-flow deposits (thin-bedded classical turbidites and thick-bedded hyperconcentrated to concentrated flow deposits) that stratigraphically belong to the Annot Sandstone infill. Slumps and internal metre-large fold axes of the deformed stratigraphic intervals indicate a main transport direction towards the northwest. The seafloor instability that led to the mass-flow events within the Mont-Tournairet sub-basin could have been favoured by high sedimentation rates in a small, confined and tectonically active sub-basin, possibly enhanced by local structural deformation associated with the Triassic evaporites on the eastern side of the Mont-Tournairet confined basin. The presence of the MTD suggests that a period of increased flexural subsidence rate and basin deformation occurred in this portion of the subalpine foreland basin. Therefore, the MTD forms a stratigraphic marker of a period of tectonic activity.

泗水县龙湾套铜矿为岩浆熔离型铜镍硫化物矿床,通过激电中梯测量圈定了若干激电异常,经工程验证,不但在这些异常中发现了9个铜矿体,而且各矿体的形态,规模与异常的形态,规模大致吻合.     

云南富宁县牛场钛铁砂矿矿床成因及富集规律

富宁地区里达断裂东侧出露大量的中三叠世印支期第一期第四亚期侵入的辉长辉绿岩体,经过漫长的风化、水解作用,岩体岩石结构构造遭受破坏,钛铁矿、钛磁铁矿、金红石等矿石矿物从原岩中彻底解离,从而形成了易开采利用的辉长辉绿岩风化壳型钛铁矿（砂）矿床.

云南威信李子埂煤矿突水治理方案分析

煤矿掘进过程中揭露了小断裂,断裂活化后,煤层下覆岩溶水涌入;矿井突水导致了龙洞坝泉暂时性断流.介绍了突水治理方案：采用物探方法寻找突水井巷,用“地表钻孔注砼法”封堵突水段井巷.该方案能彻底封堵本次突水的导水断裂和龙洞坝泉的水力联系,使龙洞坝泉涌水不会再受本次突水影响,同时,也能解除煤矿受本次突水的危害,为煤矿下一步的恢复工作奠定基础.     

云南云县新村金矿床成因类型

金矿赋存于三叠系中统忙怀组上段第二层（T2m2-2）的蚀变安山岩的地层中,矿体受断层及火山岩双重控制,近矿围岩蚀变主要有硅化、黄（褐）铁矿化、毒砂化、方解石化等.认为该矿区金矿床成因类型为与火山作用、构造作用有关的蚀变岩型金矿床,并总结了矿区的找矿标志,对在该区域寻找该类型的金矿床具有一定的指导意义.
