Documenting a joint Chinese-European study of mesothermal lode gold deposits from early pre-Cambrian rocks in a northern province of China, this volume describes the foundational geology of the Sino-Korean Platform and gives detailed descriptions of each gold deposit.
Documenting a joint Chinese-European study of meso-thermal lode gold deposits from early Precambrian rocks of East Hebei Province (NE China), introductory chapters on gold deposits, and the basement geology of the Sino-Korean Platform are followed by detailed descriptions of the individual gold deposits. These include descriptions of the lithology and structure of the host rocks, ore geochemistry and petrography, and wall-rock alteration. Radiometric ages, fluid inclusion data, and C-O-H-S-Pb isotopic compositions of ore and gangue minerals constrain the timing, physical conditions and the possible origin of mineralization. An important conclusion is that, in contrast to the Archean greenstone-hosted gold deposits in Canada, Australia and Africa, the Chinese examples occur in high-grade polymetamorphic rocks, and the main impetus for mineralization was tectonism and granitic magmatism of the late Mesozoic Yanshanian orogeny.
