Based on the database of the standards, construction process, data quality control measures and methods and processes, the authors constructed the databases of Fe, Mn, Cu, Al, Au, Ni, U and REE mineral resources for Oceanian region. Through a comprehensive analysis of the multi-source data information of geology and mineral resources, the regional metallogenic regularity was summarized, and the basic data were provided for mineral resources prediction. The database management system formed in this way makes the data management and inquiry more convenient, the expression more intuitive, and the analysis and summarization more effective. Source

Based on the data from dense sampling and accurate testing, associated with the hydrogeological condition and pollution situation of Lubei plain, the authors studied the content and the extent of organic pollution in the shallow groundwater. The results show that the shallow groundwater has been subjected to extensive organic pollution and formed many shallow contaminated areas. It is shown that organic pollutants have 13 species, with one or two species having very high content. The area coverage and extent of the contamination are controlled by the plant location of the Shengli oil field and the distribution of petrochemical enterprises. Source

The compilation of serial geological maps of Oceanian region is a concrete research work which is subordinated to the research project of 'Analysis of Mineralization Regularity and Dominant Mineral Resources Potentiality of the Major Mineralization Belts in Oceanian Region'. The collection and choice of interrelated data, establishment of database and compilation and proofreading of maps constitute a large-scale integration of geological and mineral resources data of Oceanian region, with the maps composed of 1:5000000 geological map, geotectonic map, mineral resources map, mineralization zoning and ore-prospecting prognosis map, the secondary maps comprising monomineral resources maps and the auxiliary maps consisting of geophysical prospecting map, geochemical prospecting map and remote-sensing information map, together with reference maps of some regions (states) or major monomineral resources. The compilation of the serial maps and the establishment of database may be conducive to making the acquaintance of the general geological and mineral resources situation of Oceanian region and can provide convenience for inquiring, visiting and extracting relevant data.

According to the hydrogeological condition and pollution situation of Shengli overland oil field, this paper studies the content and degree of organic pollution of the shallow groundwater and soil based on sampling and testing. The result is that the shallow groundwater and soil has been well-received by organic pollutants and formed many shallow groundwater contaminated area. Organic pollutants that was detected was 16 species, one or two content was high. The contaminated degree was controlled by the density, fixed number and history of oil extraction wells and distribution of petrochemical industrial. © 2011 IEEE. Source

Located across Indo-Australian plate, Pacific plate and Eurasian plate, Oceania has undergone long and complex tectonic evolution since Archean. Three major tectonic units can be identified according to the regional geology of this region, i.e., middle-western Australian Precambrian craton, eastern Paleozoic orogenic belt and Circum-Pacific Meso-Cenozoic island arcs. Theses three major tectonic units could be subdivided into thirteen second-order tectonic units and forty-six third-order tectonic units. The three major tectonic units exhibit different types of rock assemblage and mineralization due to the unique tectonic evolution history of each unit. Mineralization characteristics of the three major tectonic elements are summarized on the basis of a comprehensive analysis of the relationship between the tectonic evolution and the mineralization events: the mineralization of the middle-western Australian Precambrian craton mainly took place in Archean and Proterozoic, with the dominant mineral resources being gold, copper, nickel, manganese, iron, uranium, REE, lead-zinc bauxite, which were associated with the development of Australian Precambrian craton; the mineralization of the eastern Paleozoic orogenic belt mainly occurred in Paleozoic, and dominant mineral resources were copper, gold, lead-zinc, tungsten and tin, which were associated with the interaction between Palaeo-Pacific and Australia; the mineralization of the Circum-Pacific Meso-Cenozoic island arcs mainly occurred in Miocene-Pleistocene, and the dominant mineral resources produced included copper, gold, nickel and cobalt, which were related to the interaction between Indo-Australian plate, Pacific plate and Eurasian plate. An overall assessment shows that Oceania has very good iron, manganese, copper, gold, bauxite, uranium, nickel and REE resource potentials. Source
