富碱侵入岩与金成矿关系：云南省姚安金矿床 成矿流体形成演化的微量元素和同位素证据

以产在姚安富碱侵入岩体内外接触带上的姚安金矿床为对象，对成矿流体形成演化过程中的微量元素和S、C同位素地球化学进行了综合研究。研究结果表明，富碱侵入岩成岩过程中分异出的岩浆流体提供了姚安金矿床早期成矿作用所必需的成矿流体；从早期成矿阶段至晚期成矿,民矿流体经历了从以岩浆流体为主的流体体系至以大气降水为主的流体体系的转变。因此，钙碱性侵入岩成岩过程中可分异出成矿流体的过程，也存在于富碱浸入岩的成岩过程中。     

白音查干凹陷断层活动对沉积的控制作用

白音查干凹陷断层活动对沉积起着明显的控制作用。北部陡坡断层沉降速率大，使得该区霍恩和冬屋地区成为持续发育的沉积中心。变换构造带在白音查干凹陷主要表现为调节带，在凹陷的北坡桑合西地区、吉尔地区是持续发育的横向调节带，地貌上为持续存在的古构造高；南坡的白音查干调节带与达1井东调节带，分别是锡林好来与达尔其辫状河三角洲体系、达尔其与翁特沉积体系的分水岭。     

SOME EXAMPLES OF TRANSITION SPANS MINERALIZING AND ANALYSIS OF THEIR DYNAMICS

The transitional span is a special environment for deposits. Taking peat, oil-gas, metallic deposits as examples, this paper discusses the spatial-temporal transitional characteristics of mineralization in transitional regions, points out the importance of the mineralization in transition spans, and analyses their dynamics finally.     

GEOCHEMICAL EFFECTS OF MAJOR ELEMENTS DURING FLUID-ROCKS INTERACTION IN MARINWOBO FAULT IN THE SOUTH MARGIN AREAS OF ALTAI MOUNTAINS

There are four types of metamorphic rocks in the Marinwobo fault, i. e, cataclasite, mylonite,mictosite and migmatitic granite, and the formation of these rocks is due to the progressive metamorphism of the pyroclastics. The fluids play a very important role in the metamorphic process of these rocks in the Marinwobo fault, the most important feature is that the fluids not only result in the migration of the major elements of the deformation rocks, but also result in the volume loss of the deformation rocks in the deformation process. Thus the migration laws of the major elements in different stages of the progressive metamorphic process are discussed according to mass balance equations. Finally, the quantitative analysis of the mass loss and volume loss of the different rocks the in Marinwobo fault is discussed in this paper.

GIS技术在区域水资源调蓄中的应用——以滹沱河冲洪积扇地下水调蓄研究为例

在对GIS技术进行介绍的基础上阐述了GIS技术在地下水数值模拟中的主要应用;建立了基于GIS的地下水模拟模型,并将其应用于滹沱河冲洪积扇地下水调蓄研究中,调蓄结果表明,研究区现状调蓄空间为29．95×10^8m^3,漏斗区现状调蓄空间为12．83×10^8m^3;采用调蓄方案后,到2020年地下水水位持续下降的趋势得到了缓解和遏制,含水层的储水功能得到了部分恢复和涵养。
