Numerical Simulation Based Targeting of the Magushan Skarn Cu-Mo Deposit, Middle-Lower Yangtze Metallogenic Belt, China

The Magushan Cu–Mo deposit is a skarn deposit within the Nanling–Xuancheng mining district of the Middle-Lower Yangtze River Metallogenic Belt (MLYRMB), China. This study presents the results of a new numerical simulation that models the ore-forming processes that generated the Magushan deposit and enables the identification of unexplored areas that have significant exploration potential under areas covered by thick sedimentary sequences that cannot be easily explored using traditional methods. This study outlines the practical value of numerical simulation in determining the processes that operate during mineral deposit formation and how this knowledge can be used to enhance exploration targeting in areas of known mineralization. Our simulation also links multiple subdisciplines such as heat transfer, pressure, fluid flow, chemical reactions, and material migration. Our simulation allows the modeling of the formation and distribution of garnet, a gangue mineral commonly found within skarn deposits (including within the Magushan deposit). The modeled distribution of garnet matches the distribution of known mineralization as well as delineating areas that may well contain high garnet abundances within and around a concealed intrusion, indicating this area should be considered a prospective target during future mineral exploration. Overall, our study indicates that this type of numerical simulation-based approach to prospectivity modeling is both effective and economical and should be considered an additional tool for future mineral exploration to reduce exploration risks when targeting mineralization in areas with thick and unprospective sedimentary cover sequences

The Mysterious Dead and the Generation of Life:——John K. Shryock’s Anqing Ethnography Revisited

This essay explores a selection of John K. Shryock’s field data from a hundred years ago, from the province of Anhui. Focus is on the ceremonialism of ancestry and the cultural semantics of ancestor worship. The account tries to demonstrate how certain phases of such rituals connect with the construction of continuity in social life, either through the cultural idiom of the cultivation of rice, or the idiom of procreation of children. The liturgies and paraphernalia employed show symbolic complexities, the understanding of which may lead us to new insights into the culture of southern China

Public-Private Partnerships in the Electric Vehicle Charging Infrastructure in China: An Illustrative Case Study

© 2018 Kun Wang and Yongjian Ke. Effective supply of charging infrastructure is a necessary support for the development of electric vehicle and also an important strategic measure to promote energy consumption revolution and green development. The construction and operation of charging infrastructure in China is unfortunately not smooth, lagging behind the actual demand. Public-Private Partnerships (PPPs) may offer a promising way forward and accelerate the development of charging infrastructure by tapping the private sectors' financial resources and professional skills. However, PPP has not been commonly adopted in this sector yet. This paper hence studied an illustrative case of Anqing Project in China to demonstrate how governments structure a PPP deal in the electric vehicle charging infrastructures. A content analysis was conducted on the important project documents to investigate key elements including the planning, construction, risk sharing, profit distribution, and supervision during the execution stage. Based on the illustration, some key lessons and recommendations were provided to offer a reference for future charging infrastructure PPP projects in China

Transitional Public-Private Partnerships Model in China: Contracting with little recourse to contracts

Since 2013, the Chinese government has attempted to make a transition from user-pay PPP to government-pay PPP systems with the aim of facilitating infrastructure investment and government transformation. Whilst the application of government-pay PPP systems can considerably expand the areas where PPPs are suitable, the lengthy procurement time experienced in the implementation of similar systems (e.g., Private Finance Initiative (PFI)) presents a tough challenge to Chinese procuring authorities who are under increasing pressure to get the earmarked PPP projects off the ground swiftly to stem the downward pressure in the economy. The first PFI-ish project in China, the Anqing Urban Road PPP project, has been successfully tendered in May 2015 with an impressive record on procurement time. Through the scrutiny of this project, it is found that speedy procurement is achieved by leaving some of the major risks ill-defined and vaguely allocated in the tender document. However, this apparent high risk exposure did not deter investors. This research maintains that the greater risk tolerance revealed among SOE-led investors should be attributed to the power structure embedded in China’s administrative system. Whilst leveraging this mechanism can reduce transaction costs, it could hold back the participation of private investors in future Chinese PPP projects
