Porphyry copper assessment of the mesozoic of East Asia—China, Vietnam, North Korea, Mongolia, and Russia / Оценка мезозойских медно-порфировых объектов Восточной Азии: Китай, Вьетнам, Северная Корея, Монголия и Россия

The assessment of porphyry copper deposits in eastern Asia has a long history, and many people have been involved. USGS colleagues Klaus J. Schulz and Joseph A. Briskey initiated the project and participated in the first workshop, in Kunming, Yunnan, in 2002. Stephen G. Peters and Warren Nokleberg coordinated and led the initial assessment activities, prepared preliminary reports, and represented the USGS to our Chinese counterparts at several meetings. Jack H. Medlin, as USGS international specialist for Asia and the Pacific, facilitated joint project activities. Kathleen M. Johnson, USGS Mineral Resources Program Coordinator, provided spirited and constant support over the life of the project. Niki E. Wintzer and Kathleen D. Gans provided technical support.
USGS colleagues Peter Vikre, Floyd Gray, Michael L. Zientek, Arthur A. Bookstrom, and Mark M. Cocker served on an assessment oversight committee to evaluate the assessment 
results prior to publication. Technical reviews of the manuscript and GIS were provided by Floyd Gray, Karen D. Kelley, and Connie Dicken. Scientists from the China Geological Survey and the Chinese Academy of Geological Sciences generously participated in assessment meetings and provided data that would not have otherwise been available. Special thanks are due to Drs. Qiu Ruizhao, Tan Yongjie, and Chen Xiufa, who hosted the senior author for visits to copper deposits in China.
