中文摘要:从地球化学屏蔽层、沉积型黄铁矿高的δ34S值、含金硫化物的非稳定平衡、Au-As-sb组合元素矿化作用在高峰期彼此分离、热液蚀变递进性等方面，阐述了东至地区金矿化的独特性。
Abstract:The Dongzhi gold district is a metallogenic province with special character, and this paper has enumerated some of its unique features：the interface bet ween the carbo-silica argillaceous formation and the overlying calcio-argillaceous formation is a geoehemical shielding layer conducive to gold mineralization; d34S values of sedimentary pyrite are extremely high, raniging from +12‰ to 23‰; some phenomena of nonsteady equilibrium are present in auriferous sulfides, such as the extensive existence of lattice gold and the remarkable variation in As content of single arsenopyrite crystals; ore-bearing hydrothermal alterations are characterized by progressive evolution, i. e. ore-bearing host rocks were replaced successively by beresitization varying gradually from lumpy to banded or even massive form; at the peak mineralization stage, the individual elements in Au-As-Sb association were separated out in order of As, Au and Sb. These characteristics serve as indicators and criteria in prospecting for gold deposits with low grade and large reserves.
