This is the second report concerning results of a joint project between the U.S. Geological Survey and the Tianjin Geological Academy to study sedimentary rock-hosted Au deposits in P.R. China. Since the 1980s, Chinese geologists have devoted a large-scale exploration and research effort to the deposits. As a result, there are more than 20 million oz of proven Au reserves in sedimentary rock-hosted Au deposits in P.R. China. Additional estimated and inferred resources are present in over 160 deposits and occurrences, which are undergoing exploration. This makes China second to Nevada in contained ounces of Au in Carlin-type deposits. It is likely that many of the Carlin-type Au ore districts in China, when fully developed, could have resource potential comparable to the multi-1,000-tonne Au resource in northern Nevada. The six chapters of this report describe sedimentary rock-hosted Au deposits that were visited during the project. Chapters 1 and 2 provide an overview of sedimentary rock-hosted Au deposits and Carlin-type Au deposits and also provide a working classification for the sedimentary rock-hosted Au deposits. Chapters 3, 4, and 5 provide descriptions that were compiled from the literature in China in three main areas: the Dian-Qian-Gui, the Qinling fold belt, and Middle-Lower Yangtze River areas. Chapter 6 contains a weights-of-evidence (WofE), GIS-based mineral assessment of sedimentary rock-hosted Au deposits in the Qinling fold belt and Dian-Qian-Gui areas. Appendices contain scanned aeromagnetic (Appendix I) and gravity (Appendix II) geophysical maps of south and central China. Data tables of the deposits (Appendix III) also are available in the first report as an interactive database at Geochemical analysis of ore samples from the deposits visited are contained in Appendix IV.

Within the text, there are hyperlinks (or "hot links") built into each entry of the Contents and into each mention of a figure, table, section, appendix, or footnote. Hyperlinks are apparent because, as you hover over them with the mouse, the cursor changes to a pointing finger. In some cases, the hyperlinked text has a blue box around it. As you read, you can use the hyperlinks by clicking on them with your mouse and you will be moved to that view. To get back to the previous view, use the "back" button on the menu bar at the top of the Acrobat® screen or press Alt + left-arrow (Windows) or Command + left-arrow (Macintosh). World Wide Web URLs are also hyperlinks; clicking on them will launch your browser and you will be taken to that Web site.

Tip: If your copy of Acrobat Reader 5 has "Open Cross- Document Links In Same Window" ("Edit" menu under "Preferences", "General...", "Options") selected, you should DESELECT it. This will keep the main document open while you open and close other PDF files. In older versions of Acrobat, this menu item is in "File" "Preferences" "General..."
