H. Tatsch, Gold deposits: Origin, Evolution, and Present Characteristics: an Analysis of the Present Gold Deposits in Terms of the Geometrical, Mechanical, Thermal, and Chemical Aspects of the Earth’s Behavior during the Past . Billion Years (Tatsch Associates, Sudbury, Mass, 1975). 34. H. N. Wang and T. Q. Chu, The mode of occurrence of gold and some problems related to geochemistry, J. Mineral. No. 1, 84–95 (1982).

The present geothermal deposits are analyzed in terms of the geometrical, mechanical, thermal, and chemical aspects of Earth's behavior during the past . billion years. An alternative, neotectonic approach for understanding geothermal deposits is examined. This ''tectonospheric Earth model'' differs from simple ''plate-tectonics'' concepts in two fundamental respects: (1) it extends the applicable spatio-temporal domain to a depth of at least 1000 km and to a span of . . and (2) it provides a single global driving mechanism for.

Gold deposits in Jiaodong province have been mainly divided into the extensional massive quartz-vein type and the fracture-fill or disseminated type. As the tectonic setting and origin of gold mineralization are different from typical conventional orogenic gold, some studies term these deposits "Jiaodong type". However, the Jiaodong-type gold deposits show no consistent spatial relationship to granitic intrusions of the same age or evidence of metal zonation related to thermal gradients surrounding anomalously hot intrusions in cooler host rocks
