Detailed studies of tectonic unit and mineralized pedigree in each tectonic unit and each period provided that tectonic evolution passed an evolutionary sequence from early extension - transition - late compression that correspond to mineralization - sediment and submarine eruption - exhalation mineralization - moderate to acid magma and tectonic hydrothermalism that are relevant to mantle - derived magma and volcanic activities ; the mineralized pedigree can be indicated as mantle derived - inner basin and deep source - crust source ore - forming materials 对各时期、各构造单元的成矿谱系进行了详细研究,提出构造运动演化从早期拉张过渡晚期挤压的演化序列,分别对应于以幔源岩浆和火山活动有关的成矿作用沉积及海底喷流?喷气成矿作用中酸性岩浆及构造热液成矿作用;在成矿物质上由幔源盆内及深源壳源的成矿谱系。
In order to solve problems existing in current measuring methods for radon exhalation rate ( such as the effect of unequilibrium radon and its progeny , humidity effect , leak and back - diffusion effect , etc . ) , based on the principle of surveying radon and its progeny in the medium surface , a rapid arid accurate method for measuring radon exhalation rate taking advantage of the rad7 radon detector was established 摘要本文根据介质表面氡析出率的测量原理,针对目前国内外现有的氡析出率测量方法中存在的一些问题,如对氡及其子体的不平衡影响、湿度效应及泄漏和反扩散等影响未作修正等,实验研究了一种用rad7型氡气检测仪快速测定土壤、岩石、建材和尾矿等介质表面氡析出率的方法。
On the toilet table the bouquets - roses , lilacs and hyacinths - appeared like a very ruin of flowers . their perfume was strong and penetrating , while through the dampish air of the place , which was full of the spoiled exhalations of the washstand , came occasional whiffs of a more pungent scent , the scent of some grains or dry patchouli ground to fine powder at the bottom of a cup 梳妆台上放着许多花束,有玫瑰,丁香,风信子,花堆得像要坍塌下来,散发着一股浓郁的沁人心脾的芳香室内空气潮湿,洗脸池中散发出的一股淡淡气味中,不时飘出一阵刺鼻的香味,那是从一只高脚杯底部的九根捏碎了的干广藿香茎中发出来的。
There are two series of cu , au deposits , the stratiformed deposits and the intrusive - related ones in the mineralization belt of the middle and lower reaches of the yangtze river area . comparative studies on forming geodynamic backgrounds , geological and geochemical conditions of the ore - forming systems have been undertaken in this paper . the stratiformed deposits were formed in hercynian period by submarine exhalation - sedimentation sedex of hot brine through the synchronous basement faults in a tensional environmental , and the intrusive - related deposits were formed in yenshanian in a tensional or a transitional period to tensional environment during the upper mantle doming by water - rock interaction and complex transport - chemical reaction dynamic processes , the ore - forming fluids were mainly magmatic water from melt - fluid partition and some meteoric water 成矿流体系统形成的地球动力学背景及地质地球化学条件对比研究表明,赋存于石炭系中的层状铜金矿床是海西期拉张背景下热卤水沿同生断裂经喷流作用形成的海底喷流热水沉积矿床与燕山期中酸性侵入岩有关的铜金矿床是在上地幔隆起张性或向张性过渡背景下形成的,是中酸性岩浆经熔体流体分离作用形成的岩浆热液与大气降水混合,经水岩作用等复杂的输运和化学反应耦合过程的动力学产物。
By the study on the isotopes and fluid inclusions in the area , with analysis of their geodynamics background , it shows that the source material of pb - zn deposits and au deposits are both related to submarine exhalation , and the mineralization backgrounds of hg - sb deposits and au deposits are the same 通过总结该地区的同位素及流体包裹体资料,结合其他地球化学动力学背景分析认为:铅锌矿和金矿物质来源均与海底喷流作用有关,而金矿和汞锑矿则具有相同的成矿背景。
Exhalation (or expiration) is the flow of the respiratory current out of the organism. In humans it is the movement of air out of the bronchial tubes, through the airways, to the external environment during breathing.
