| 1. | Effect of intrusive magmatic rock on seam gas preserving in anlin coal mine 安林煤矿岩浆岩侵入对煤层瓦斯赋存的影响 |
| 2. | Preliminary study on the minerogenetic model of mesozoic volcanic - magmatic rocks in eastern jilin , china 云南断陷盆地浅循环岩溶水赋存规律初步研究 |
| 3. | Geology and genesis of the yao ' an gold deposit related to alkali rich magmatic rock in yunnan province 云南姚安与富碱岩浆活动有关的金矿床地质及成因 |
| 4. | Variability analysis of overlying strata movement rule and mining field pressure under super - thick magmatic rock 巨厚岩浆岩下开采覆岩移动规律及采场压力变异性分析 |
| 5. | The magmatic rock intrudes relative seriously in wangying colliery , rock - burst and gas outburst mainly take place near igneous rock wall 摘要王营煤矿的岩浆岩侵入比较严重,冲击矿压和瓦斯突出多发生在火成岩墙附近。 |
| 6. | These studies , therefore , suggest that the songsugou peridotite is not a tectonic massif of the upper mantle but a ultramafic magmatic rock body crystallized in deep crust and tectonically emplaced in the upper crust 从而证明了松树沟橄榄岩体并不是上地幔岩石的残片,而是由岩浆在深部地壳环境下结晶而成并以固态构造侵位于地壳的上部。 |
| 7. | Based on the distribution and petrochemistry of magmatic rocks , the techonic background of sedimentary basin and the mechanism of magmatic activity at the late hercynian in nanpanjiang depression and its adjacent areas , southern china , have been studied 摘要南盘江坳陷及邻区海西晚期岩浆岩分布显示有从中、西部大规模玄武岩喷发中东部中酸性岩浆活动东南部花岗岩侵入的演化规律。 |
| 8. | The green - rock has following features : ? he stratiform green - rock ' s mode of occurrence is conformable with that of the strata , and there are typical syngenetic sedimentary structure in the rock ; ( 2 ) the stratiform green - rock is constituted mainly by bistagite without zonal distribution around magmatic rocks 作者首次提出赋矿的绿色岩建造概念。其中层状绿色岩是佛子冲矿田层状、似层状矿体的直接赋矿围岩,这种层状绿色岩一直被视为矽卡岩。 |
| 9. | This paper has studied the ore - forming process of this ore belt and magmatic rocks , major vein rocks , wall rock alterations , trace elements and geochemical characteristics of various epochs , probed into the regularity of element enrichment and variation , and established geological - geochemical ore - prospecting criteria 研究该矿带成矿作用和在不同时代岩浆岩、主要脉岩、围岩蚀变、微量元素及地球化学特徵, ?解元素富集变化规律,建立了地质地球化学找矿标志。 |
| 10. | The study covers regional stratigraphy , regional geological structures and their evolution ; deep - large fracture system and building - moutain straps in the basin ; distributing of mineralization concentration area and mineralazition characteristics of different metal fields ; volcanic magmatic activity and magmatic distributing ; the petrology , element geochemistry features of the magmatic rock series ; the relationship between magmatic distributing and mineralization ; the relationship between magmatic forming - age and mineralization ; the relationship between magmatic form and mineralization ; source of mineral materials , source of hydrothermal solution and source of mineralizing agent ; transport forms of metal in the solution ; the ore - forming geochemical mechanism , etc . it turns out as follows : ( 1 ) lanping basin formed in the linkup of the plates and it was propitious to form deep - large fracture 研究内容包括:区域地层及区域构造演化;盆地深大断裂系统及造山带;区域地球物理场;矿集区矿床的时空分布、矿化特征;岩浆岩活动与岩浆岩分布;岩浆岩岩石学特征;岩浆岩元素地球化学特征;岩浆岩分布与成矿的关系;岩浆岩成岩时代与成矿的关系;岩浆岩组成与成矿的关系;成矿物质的来源,成矿流体的来源;成矿物质搬运、富集的地球化学机理等。研究结果表明:兰坪盆地发育于板块的拼接地带,有利于发育深大断裂系统。 |
