地洼区的过渡间成矿及其意义──以东南地洼区铀矿为例
There is a close relationship between occurrence of nonmetallic minerals and tectonic evolution of geosyncline,platform and diwa(geodepression)on the western margin of the Dongting diwa.
洞庭地洼西缘非金属矿产的产出特征与地槽、地台及地洼构造的演化具有密切的关系。
Based upon diwa metallogenetic theory,the division and evolution of geotectonic units in the province were studied in this paper,and there are 2Ⅰ class、3Ⅱ class、7Ⅲ class and 45Ⅳ class tectonic units in the whole province limits.
本文据地洼成矿理论,对省内大地构造单元的划分及演化进行了研究,将其划分为2个Ⅰ级、3个Ⅱ级、6个Ⅲ级、45个Ⅳ级大地构造单元,认为中生代由于地台活化转入地洼阶段是省内大地构造演化的一大特点。
The favorable parts for bonanza ores are beneath clay zones and adjacent to pyrite deposit or in depression and funnel.
成矿盆地斜坡下部的铝土矿带与硫铁矿相邻地段、成矿洼地、凹地及漏斗是铝土矿富矿赋存部位及找矿有利地段。
This algorithm could fast determine disconnected depressions and their influence areas on the basis of acquiring digital tide-coordinates shorelines(DTS).
此算法在提取数字伴潮海岸线(DTS)的基础上,快速确定不连通的洼地及其影响域。
Disconnect depressions are determined depending on types of DTS,and influencing areas of them are computed efficiently.
根据DTS的类型确定不连通的洼地,并快速计算其影响域,同时合理地确定潮滩与水面模型的表达方式,正确构建和显示淹没区。
This paper chiefly introduced the geology structure and lithology characteristic of Wulapo lowland groundwater reservoir in Urumqi.
介绍了乌拉泊洼地地下水库的地质构造和岩性特征,分析了乌鲁木齐河地表来水过程,建立了地下水数值模型和水均衡模型,计算了洼地各项水资源量,估算了地下水库年调蓄量和储存量,并模拟计算了洼地地下水库与乌拉泊水库联合调度方案,确定了洼地水源地的地下水最大开采能力,提高了乌拉泊水库的调蓄功能,对缓解乌鲁木齐市水资源综合效益,减少河道弃水量,降低月缺水量,缓解供水矛盾具有重要的现实意义。
