我国地质文化村（镇）空间分布特征及影响因素研究

地质文化村（镇）是地质文化科普的重要窗口,也是所在区域经济社会发展的重要依托,对其空间分布特征及影响因素的研究对我国地质文化村（镇）的进一步评定和可持续发展具有重要意义。运用最邻近指数、不平衡指数、核密度分析和地理探测器方法,对我国50个地质文化村（镇）的空间分布特征及其影响因素进行研究,研究表明：①地质文化村（镇）的空间分布类型为随机分布型;②各省（市、区）地质文化村（镇）数量差异明显,空间分布不均衡,呈“东多西少”格局;③地质文化村（镇）形成1个高密度核心区、2个次高密度集聚区、1条核心延长带;④影响我国地质文化村（镇）空间分布格局的因素由特色地质资源、自然条件以及社会经济与人文资源3个一级指标构成,其中社会经济与人文资源对地质文化村（镇）空间分布影响最大且效果显著。在今后地质文化村（镇）的评定建设中,应加强中西部地区地质文化村（镇）的建设和申报;适当给予中西部地区地质文化村（镇）评定倾斜;加大地质文化村（镇）宣传力度;充分发掘地质特色及民俗文化,加强地质文化村（镇）与文化的融合。

Geological information

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.     

煤田地质勘探中的一些工程地质工作

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。

Progress of Deep Geological Survey Project under the China Geological Survey

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.     

Simulation of Geological Contacts from Interpreted Geological Model Using Multiple-Point Statistics

Applications of multiple-point statistics (mps) algorithms to large non-repetitive geological objects such as those found in mining deposits are difficult because most mps algorithms rely on pattern repetition for simulation. In many cases, an interpreted geological model built from a computer-aided design system is readily available but suffers as a training image due to the lack of patterns repetitiveness. Porphyry copper deposits and iron ore formations are good examples of such mining deposits with non-repetitive patterns. This paper presents an algorithm called contactsim that focuses on reproducing the patterns of the contacts between geological types. The algorithm learns the shapes of the lithotype contacts as interpreted by the geologist, and simulates their patterns at a later stage. Defining a zone of uncertainty around the lithological contact is a critical step in contactsim, because it defines both the zones where the simulation is performed and where the algorithm should focus to learn the transitional patterns between lithotypes. A larger zone of uncertainty results in greater variation between realizations. The definition of the uncertainty zone must take into consideration the geological understanding of the deposit, and the reliability of the contact zones. The contactsim algorithm is demonstrated on an iron ore formation.
