This paper introduces the geologic setting, deposit geology, geophysical/geochemical anomalies, alteration, ore body geology, ores quality, mineralization period and stages of Rongna super large porphyry-epithermal compound copper deposit, Gaize county, Tibet, and discusses the source of mineralization elements. Rongna copper deposit is a compound deposit with high-sulfur epithermal deposit on the top and porphyry deposit on the lower part, although it is in the same structure-magma. It is the largest copper deposit in Duolong mineralization concentration district, with 332+333+334 resource up to 11 million tons at a grade of 0.53%. This paper clarifies the deposit types, geology, structure and mineralization, establishes a geological model to predict ore deposit in Rongna deposit, southern Tiegelong, and summarizes its structure, and analyzes the further prospecting and resource potential combined with CSAMT.

This paper selects two large sea salt producers in Bo Sea bay to study the Li content changes in their salt making processes with results showing that Li is enriching from sea water to final brine. LiCl becomes 97.27 mg/L and 138.15 mg/L in final brines in these two fields, reaching the cutoff grade of the brine Li. During producing sea salt, the crystallization of salts has a low absorption to Li+. According to China's sea salt production and Bo Sea Bay sampling data, Li metal is estimated to be 455.95t in final brines of China's all sea salt fields in 2013, equivalent to 2430.23t in Lithium Carbonate. Li content is high sea water in sea salt fields and tends to be concentrating in the final brine. Extracting Li technology is universal, which provides a prosperous outlook in extracting Li from sea salt field's brines. Extracting Li directly from sea water, if matures, is the future technology.

This paper makes performance measurement among 67 listed mining companies, based on their annual reports from 2010—2013, calculates the economic value added (EVA), the return rate of EVA and the growth rate of EVA. The results show the subordinate industry types of mining industries dont have a significant influence on the return rate of EVA. Performances have gotten deteriorated in coal mining and processing, oilgas mining and mining services since 2010, but their performance differentiation reduces. Performances have gotten better in ferrous and nonferrous metal. The EVA in mining services has increased at the fastest speed, and that in nonferrous metal industry has fluctuated at most. This paper gives advices for mining industry in improving the economic value added from investing on R&D, constructing engineering projects, raising capital effectiveness, intensifying financial management and setting up EVA promotional system.

This paper, uses data envelopment analysis (DEA) to evaluate the innovation ability in eastern and western China and analyzes their innovation ability difference, and shows a higher intelligence allocation efficiency in the western, and a higher commercial result allocation efficiency in the eastern. This paper also studies the issues in innovation process and provides suggestions setting up interactive mechanism. The western and eastern shall create an effective intelligence alliance and innovation technology alliance to focus on resources-based motives, benefit allocation standard, government’s service and continued policy support.

The injection of carbon dioxide in the late period of oilfield development can reduce viscosity of crude oil and saturation of residual oil, which consequently increase recovery. This paper, based on correction of the flow equation of carbon dioxide miscible flooding, establishes a model by the method of characteristics to analyze the impacts of effective viscosity ratio, vertical heterogeneity, oil saturation, and water alternating gas on carbon dioxide miscible flooding. The results show that the more effective the viscosity ratio, the higher the vertical heterogeneity, the lower the oil saturation and the more the water alternating gas, the lower the oil recovery. This method is of high value to evaluate the early stage of carbon dioxide miscible flooding. 

Gold enterprises' acquisition and reconstruction prevails recently. This paper presents that the four-environmental issues shall be taken into consideration during expansion, including geological, social, natural and political environments.

China’s international petroleum diplomacy is being challenged by the speeding economic globalization. China is currently starting to construct the petroleum reserve, so it is important to carry out petroleum diplomacy. This paper, based on a brief introduction to petroleum resources, expounds China’s petroleum diplomacy in the 21st century and presents a strategy that China’s petroleum industry shall be based on internal resources, diversify petroleum supply worldwide and improve domestic petroleum reserve.
