Description:

Abstract:

These data sets include deposit description, location, and geochemistry of sedimentary rock-hosted (Carlin-type) Au deposits in P.R. China. Deposit data was compiled by U.S. Geological Survey and Tianjim Geological Academy into a series of tables (.xls and .csv) provided in Open-File Report 02-131, Appendix III and IV. 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.

Purpose:

The data was prepared in cooperation with the Tianjin Geological Academy to increase the knowledge base of Chinese gold deposits for research, development and for spatial analysis.

Supplemental_Information:

The tables represent a series of worksheets that evolved as data was collected. Initial data came from a few China deposit records in the U.S. Geological Survey's Mineral Resources Data System (MRDS). Some field name inconsistencies occur in the worksheets that are remnants from the earlier MRDS field names. For example, the MRDS field STATE NAME in one of the tables is equivalent to the field name PROVINCE in other tables. Some tables represent earlier stages of the data gathering process as reflected by the lesser amount or duplication of data. Only two of the deposit description tables have coordinate information. The fields DEPOSIT NAME or DEPOSIT could be used to link coordinate data to other tables such as the deposit geochemistry.

The tables represent a series of worksheets that evolved as data was collected. Some field name inconsistencies are present for example, the field STATE NAME in one table is equivalent to the field name PROVINCE in other tables, the field DEPOSIT NAME is equivalent to the field DEPOSIT, the field COMMODITIES is the same as the field COMMODITY and the field HOST AGE is the same as the field UNIT AGE. Some tables represent earlier stages of the data gathering process as reflected by the lesser amount or duplication of data. Only two of the deposit description tables, Appendix_III_deposits and Appendix_ III_table2 have coordinate information. The fields DEPOSIT NAME or DEPOSIT could be used to link coordinate data to other tables such as the deposit geochemistry.

Source_Contribution:

Data sources included Chinese internal reports mainly from the Ministry of Metallurgical Industry and Gold Bureau, Tianjin Geological Academy, U.S. Geological Survey's Minerals Resources Data System (MRDS) and USGS geochemistry data.

Process_Step:

Process_Description:

Data was gathered from Chinese and English language journals, internal reports and databases of the U.S. Geological Survey and the Tianjin Geological Academy, and the Chinese Gold Bureau as well as from field visits and observations. (The original data in Open- File Report 446 version 1 was updated and corrected over a 5-year period.)

Source_Used_Citation_Abbreviation: Li and Peters (Version 1.3), 2001

Process_Date: 2001

Process_Step:

Process_Description:

Updates to the database (Of98_466.mde) that include maps and photos of deposits, deposit information, and a geochemical model. The new maps and photos of the deposits can be found in the "MAPS & PHOTOS" section. Photos include SEM photos of ore rock, as well as photos of the deposit itself. The geochemical model can be found in the "GEOLOGY & GEOCHEMISTRY" section.

Process_Step:

Process_Description:

Several modifications and additions were made to the Access Database as follows: (1) Tables were updated with more accurate latitude and longitude locations and new occurrences were added for the sedimentary rock-hosted gold deposits under the "GEOGRAPHY" section. The original number of 114 occurrences in version 1.1 of Open-File Report 98-466 is now 165 occurrences in this version 1.2 and the more accurate locations are now useful for spatial analysis. (2) New Scanning Electron Microscope (SEM) photographs of polished sections from gold ores were added under the "MAPS & PHOTOS" section. A link to these SEM photographs also was added under "MINERALOGY" (found under "GEOLOGY"). (3) Geochemistry tables were added for gold ore specimens collected in 1997 (Hebei, Guizhou and Gangzi Provinces) and in 1999 (Shanzi, Sichuan, and Yunnan Provinces) under the "GEOLOGY & GEOCHEMISTRY" section. Other miscellaneuos editorial adjustments have also been made in version1.2.
