Abstract:Apart from their rich reserve, high grade, wide distribution, numerous genetic types and various positions of occurrence, mercury depositsin Guizhou province are to a great extent under the control of. tectonismin their mineralization,transformation,enrichment and distribution, as can be seen from the orientation, zonation, equidistance and gradually varying manifestations of their spatial distribution. This has led the author to suggest that a combination of a structural stress field and certaingeochemical and geophysical fields may be regarded as one single mineral-structural domain. Thus, in Guizhou province, the regions occurringmercury can be divided into several structural domains of mercury ore according to the identity or similarity of structural systems, combinationof minerals or elements, and types of ore deposits. Six grades have been classified in the light of the structural controlof mercury deposits: 1) Sichuan-Guizhou-Hunan mercury metallogenic province, which is under the control of the third uplift zone of the Neo-cathaysian tectonic system; 2) structural domains of mercury ore. governed by leading tectonic systems; 3) mercury ore zones, governed bylarge anticlines or anticlinoriums within the structural domain; 4) mercuryore fields, governed by the superposed position of the obverse structuresin the tectonic systems; 5) mercury ore dEposits, dominated by the minorfolds or faults; 6) mercury ore bodies, dominated by some favourableoositjons possessed by srriall folds or faults or both of them.There have been recognized 5 structural domains of mercury ore, 28 mercury ore zones and 7 mercury mineralization zones for Guizhou Province.The author feels convinced that tectonism is one of the major factors affecting and promoting the migration of mercury-bearing matprials andthe intensity of structural stress zone decides the degrees by which mercury deposits have been reformed.
