Discovery of Eoarchean Meta-Dioritic Rocks in Anshan Area, China and Its Geological Significance

In the Anshan area of Liaoning Province, an occurrence area of the oldest rocks in the world,the meta-dioritic rock of Eoarchaean has recently been found as enclaves in the 3. 8 Ga Dongshan banded trondhjemitic rock. It has relatively high contents of REE (w(∑REE) = 149. 3×10-6) and unmarked LREE enrichment over HREE (wn (La)/wa (Yb) = 6. 99). Eight analysed zircon grains yield a well-defined discordia with an upper intercept of 3. 65 Ga. Some of the data points give an important in formation of more ancient zircon existence in the rock. The rock shows unusually low ε(Nd, 3. 8 Ga) values of - 1. 15 to -1. 24 and large tDM age of 4. 15-4.16 Ga. The geological significance of the discovery is briefly discussed in this paper.

Relationship Between Economic Growth and Water Environmental Quality of Anshan City in Northeast China

Based on the decomposition model of environmental quality and univariate regression model,the relationships of industrial wastewater drainage with economic scale,economic structure,and technological level in Anshan,a mining city in Northeast China,were studied. The results showed that,due to scale effect,the drainage of three important industrial wastewater pollutants(COD,NH3-N and petroleum) increased 8505t,671t and 384t,respectively,and due to structure effect,those pollutants drainage increased 3996t,174t and 120t from 2001 to 2006. While due to technological effect,the drainage of COD,NH3-N and petroleum reduced 4452t,458t and 331t,and due to cross effect,those pollutants drainage reduced 7270t,575t and 476t simultaneously. Meantime,the relationships between household consumption structure and domestic sewage discharge were analyzed,and domestic sewage discharges in different income levels were also compared. The results showed that,the domestic sewage discharges would increase 376t with 1000 yuan(RMB) increased in the traffic and communication consumption,and they would be 344t,219t,428t,1873t,respectively,in housing consumption,food consumption,medical consumption,miscellaneous commodity consumption. The proportion of domestic sewage discharge increased for high income residents significantly,but reduced for lower income residents. The industrial wastewater pollutants drainage tends to be reduced by technical progress,while domestic sewage discharge will be a more important factor for urban water environment quality.

Research of the Farmland Protection Based on Food Security——A Case Study of Anshan City in Liaoning Province, China

The quantity and quality of farmland is the key factor determining grain production capacity, so protecting farmland has become the key to guaranteeing food security. I take Anshan City in Liaoning Province as the study area which has its own particularity in terms of protecting farmland. Based on the prediction of population, coupled with the relevant data concerning farmland area, the per unit area yield of grain, the prediction and analysis of the balance of supply and demand of farmland in Anshan City are conducted. The results show that in the year 2010, the maximum supply amount of farmland that the city can offer is 239 000 hm2, and in the year 2020 the maximum supply amount of farmland that the city can offer will be 238 000 hm2; in the year 2010, the maximum demand amount of farmland is 204 186.02 hm2, and in the year 2020 the maximum supply amount of farmland will be 226 409.61 hm2. So the supply amount of farmland that the city can offer can meet the need of grain production objective. Some problems concerning farmland protection are pointed out in order to provide beneficial exploration of the farmland protection based on the model of food security.

Non-seismic geophysical analysis of potential geothermal resources in the Longgang Block,Northeast China

Although geothermal energy has many clear advantages,including its sustainability and environmentally friendly nature,research into potential geothermal resources across the Longgang Block,Northeast China,has been limited.Here we present the first analysis of the potential geothermal resources in this region that employs joint geological and non-seismic geophysical methods to identify target areas that may be economically viable.We acquire and analyze high-precision gravity,magnetic,and magnetotelluric sounding data,which are constrained using the petrophysical parameters of outcropping rocks across the Longgang Block,to conduct a comprehensive evaluation of the region’s deep geological structures and their geothermal resources potential,with a focus on identifying faults,rock masses,and thermal storage structures.We find that Archean granitic gneiss and Mesozoic rock masses in the deeper section of the Longgang Block possess weak gravity anomalies and high resistivities.We also identify thermal storage structures near these deeper geological units based on their extremely low resistivities.The data are used to infer the dip and depth of known or hidden faults,to constrain the spatial distribution of intrusive rock masses,and to determine the spatial distribution of subsurface thermal storage structures.The potential of the target areas for geothermal resources exploitation is divided into three grades based on contact depths between faults and thermal storage structures,and the scale of their thermal storage structures.Our results suggest that a joint non-seismic geophysical approach can be effective in locating and evaluating geothermal resources in complex geological settings.

基于鞍山式铁矿成像光谱的融合算法研究

铁矿资源是我国经济发展和社会进步的物质基础。在铁矿开采过程中,快速精准地确定铁矿品位,对矿山开采决策及经济效益具有重要影响。高光谱成像技术具有影像覆盖范围广、精度高等优势,已广泛应用于矿石分类及成分反演等领域。然而目前高光谱成像传感器的波段范围主要为可见短近红外(Vis-SWIR)和近红外(NIR)两类,且两类数据多为独立获取,缺乏连续性,采用单一数据所建模型的精度往往偏低。因此融合多传感器所获光谱数据,可有效解决单一传感器波段范围小、包含目标特征波段少等问题,提高基于高光谱成像技术的铁矿品位反演精度。使用Pika L与Pika NIR-320高光谱成像仪,分别在Vis-SWIR与NIR两个波段范围内采集鞍山式铁矿的成像光谱数据,提出了基于互信息(MI)的光谱串联融合方法,该方法首先对两组光谱数据进行预处理,然后对处理后的数据进行互信息计算以此对光谱数据进行串联融合。最后分别以Vis-SWIR、NIR以及基于不同波段串联融合的光谱数据为数据源,建立RBF神经网络品位反演模型,并以融合前后光谱数据所建模型的准确性与精度为融合算法有效性的判别指标。结果表明,光谱数据串联融合后所建模型的准确性与精度高于单独使用Vis-SWIR、NIR光谱数据所建模型的准确性与精度。与基于其余波段串联融合的光谱数据相比,在基于互信息计算得出的959.89nm处串联融合后光谱数据所建模型的准确性与精度最高,R2为0.88,RPD为2.97,RMSE为4.464,MAE为3.32。该研究针对多传感器光谱融合提出了一种新思路,对成像光谱技术应用于铁矿品位反演具有现实指导意义。

基于高光谱图像的鞍山式铁矿品位反演方法研究

铁矿品位是评价铁矿贫富程度和经济价值的重要指标,铁矿品位的检定效率对铁矿开采效率具有重大影响。鉴于高光谱图像在物质分类与含量反演等领域具有分析速度快、准确性高、无破坏性等优势,分别在可见光-近红外(VIS-NIR)与短波红外(SWIR)两个波段范围内采集鞍山式铁矿的高光谱图像,探讨基于高光谱图像实现鞍山式铁矿品位反演的可行性。首先,提取高光谱图像感兴趣区(ROI)中的平均光谱代表对应样本的光谱数据,分别采用多元散射校正(MSC)与标准正态变量变换(SNV)对其进行光谱变换。然后,分别利用蒙特卡洛无信息变量消除(MCUVE)、竞争性自适应重加权采样(CARS)和连续投影算法(SPA)提取变换前后光谱数据的特征波段。最后,利用径向基函数神经网络(RBFNN)和极限学习机(ELM)分别建立鞍山式铁矿品位的定量反演模型。结果表明,在VIS-NIR范围内的光谱数据,经MSC变换后,利用CARS提取的特征波段建立的ELM品位反演模型效果最优(R^(2)=0.90,RPD=3.02,RMSE=3.27,MAE=2.77)。将MSC-CARS-ELM模型应用于鞍山式铁矿样品的VIS-SWIR高光谱图像,能够生成像素级的铁矿品位分布图。该研究为快速、有效地实现鞍山式铁矿品位反演及可视化提供了一种新方法,在地质采矿领域具有重要的应用价值。
