鲁中“淄河式”层控铁矿床岩相特征及形成机理

The Lower Palaeozoic system is a series of iron-bearing rocks consisting mainly of shallow sea-facies carbonates. On the basis of micrafacies analysis of the carbonate rocks,the Lower Palaeozoic sedimentary sea basin is divided into two broad sedimentary-structural regions,four sedimentary facies and nine subfacies. Original iron-rich carbonates were deposited in the restricted basins, such as salt-lake, lagoon, etc. Over the long period of geological history, the original iron formations were reconstructed by late tectonic processes to various extents. Geological observations and studies of the equilibrium mechanism of oxygen and sulfur isotope fraetionation and the composition and temperatures of fluid inclusions in the minerals indicate that thermal brines played an important role in the reworking process of the original iron-rich carbonate rocks, which thus led to the formation of sedimentary-reworked strata-bound ore deposits.

浅谈无人机技术在测绘工程中的应用与实践

改革开放以来,我国科技水平发展迅速,测绘测量技术也有了很大进步。无人机技术的快速发展,使其在越来越多的领域获得了广泛的应用,测绘工程就是其中十分重要的领域。测绘工程主要测量内容包含了地形测量与地形测绘两个部分,在以往开展测绘工程时,不仅需要购买许多专业的测量设备和仪器,还需要工作人员到现场进行实地勘测,而无人机技术的运用则能够很好地解决这样的问题,并具有扩大测量范围、提高地形测量安全性以及缩减测绘成本费用等优势。当下无人机技术在海岸线地形测量、城市规划测量以及矿山测量中发挥了重要的作用。
