地质建造分析是区域地质研究中的一个重要方面,旨在了解地质建造类型与特征,分析区域地壳结构及其稳定性,研究一定地质建造与不同矿石建造在分布上的关系,正确地确定含矿地质建造。由此不难看出,各个矿种的预测首先要以区域地质建造分析为基础。合理地划分地质建造类型是地质建造分析的前提。在区域地质研究中只有根据客观实际确定地质建造类型的划分方案和准则,深入研究各类地质建造的特征,才能比较客观地并有科学依据地预 相似文献

在当前国內加强区域地质调查工作,提高地质研究程度的时刻,介绍国外近一、二十年来区域地质工作的一些重要进展,是很有必要的。这是因为,世界地质是一个统一的整体,要总结全球的地质历史和发展规律,不了解中国这一重要局部的地质情况及其特征是办不到的,而要深入探讨中国的区域地质特征并正确阐明其发展规律,不了解全球地质和 相似文献

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ1 roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
