The need for rapid storage and retrieval of geologic information is discussed briefly. The writer proposes to encode such information on perforated cards, from which it can be transferred to any other recording device. Hopefully, eventually, there will be an international arrangement where such information can be retrieved rapidly and used effectively anywhere in the world. Three examples are chosen to show how the proposed system works: A stratigraphic section, igneous phenomena, and tectonic deformations. These are set up in three tables representing the perforated cards and the proposed items are discussed in some detail. – E. Ingerson. 相似文献

煤田地质勘探工作,过去多侧重于煤炭资源的勘探,对与矿井(含露天矿,以下同)设计、施工、生产有较大关系的工程地质工作有时重视不足,如精查报告中,对第四纪地质的章节阐述就极为简单,对勘探区域内(尤其是工业广场、工人村等建筑范围)的物理地质现象、地形地貌、岩土的物理力学性质和工程地质条件等所做的工作就更显不够,以致不能较好的指导设计、施工与生产。因此,在煤田地质勘探中做好工程地质工作,是当前一项紧迫的任务。 相似文献

正1 Introduction Geological outcrops or sections are the basis of geological research.However,the traditional methods for presenting them are mainly photos which fall short of delivering a true visual sense (Deng et al.,2009;Hou et al.,2014).With the continuous development of image acquisition technology using single-lens reflex camera (SLR camera),image synthesis,large file storage and acquisition,panoramic visualization and network technology,high-resolution panorama as a means to display 相似文献

Geological solar compasses. The magnetic properties of some rocks (notably basalts and peridotites) may cause large and unpredictable aberrations of the usual geological compass. Complications are then avoided by using a watch and a solar compass, of which two types for geological use have been developed. The horizontal solar compass has the virtues of simplicity and universality; its reading, however, does not give immediately the desired azimuth. Reduction graphs are easily calculated, but valid only for a specific time of year and geographical latitude. The equatorial solar compass can be read directly. Its use, restricted to the middle and high latitudes, is as convenient as of an ordinary geologist's compass. 相似文献

Serving as a way to understand the material composition, structure, and dynamic process of the Earth’s interior, deep earth exploration is driven by not only mankind’s pursuit of natural mysteries but also mankind’s basic need to obtain resources and guarantee economic and social development. The first phase of deep earth exploration of China (SinoProbe) was carried out from 2008 to 2016 and tremendous results were achieved. In 2016, the China Geological Survey launched a Deep Geological Survey Project (also referred to as the Project) to continuously explore the deep Earth. Focusing on the national energy resources strategy, the Belt and Road Initiative, and major basic issues of the geological survey, the Project was carried out in Songliao Basin (an important energy base in China) and major geological boundaries and tectonic units including Qilian Mountains-Tianshan Mountains and Qinzhou-Hangzhou juncture belt. The purpose of it is to reveal the process, structure, and forming patterns of the deep ore deposits and petroleum reservoirs, clarify the evolutionary pattem and controlling factors of Mesozoic environmental climate, and discover deep fine structures of key orogens, basins, and mountains by comprehensive geophysical exploration and scientific drilling. Great achievements have been obtained after more than three years of efforts, including a cumulative 1552 km of deep seismic reflection profiles and magnetotelluric profiles, an ultra-deep continental scientific drilling well, a scientific drilling pilot hole, and a magnetotelluric array and a portable broadband seismic array, both of which cover South China. Moreover, significant progress has been made in ultra-deep drilling technology, deep oil and gas discovery in Songliao Basin, and basic geological issues of Qilian Orogen and Qinzhou-Hangzhou juncture belt in South China, greatly accelerating the deep earth exploration in China and further consolidating China’s position as a power in deep earth exploration. 相似文献
