Abstract

Abstract

This paper addresses the possible source, evolution and accumulation patterns of the ore-forming compositions, on the basis of the geological research, the statistical analysis, and the research into the Archean strata, the Mesozoic intrusive complexes and the chemical composition of gold deposits in different ages in the western Shandong uplift terrain. Then this paper suggests the concept of and the quantitative calculation method for the ore-forming activity of the elements in the mineralized source beds (rocks). The research shows the following three points: (1) In the western Shandong uplift terrain, the initial source of the gold is the Archean greenstone belts characterized by the bimodal gold distribution. (2) A conspicuous inheritance can be observed on the ore-bearing formation in terms of the mineralized compositions of different kinds of gold deposits despite of the different ages and different mineralizations from the Archean to the Mesozoic. (3) The characteristics of epigenetic hydrothermal deposits are determined to a great extent by the ratio between the excessive population of mineralized elements and its corresponding background population in the ore-bearing formation, and also by the average content of mineralized elements in the excessive population.
