摘要
Abstract
Xincheng gold deposit in Shandong is located in Jiaobei uplift of the North China plate.The origin of the deposit is hydrothermal alteration, and Jiaojia fault is the main ore-controlling structure.It is crushed zone alteration type gold deposit.According to the timing of mineralization, the metallogenic stage is divided into four metallogenic stages and five metallogenic ages, such as gold-bearing quartz siderite pyrite stage (Ⅰ), quartz-polymetallic sulfide stage (Ⅱ), quartz-pyrite stage (Ⅲ) and Quartz-calcite stage (Ⅳ).The typomorphic characteristics of pyrite are closely related to the gold content.The pyrite typomorphic characteristics are different in different metallogenic stages and metallogenic ages.Regarding typomorphic characteristics of pyrite from different metallogenic stages and metallogenic ages as the study object, through study on morphological characteristics, it is regarded that pyrite with poor crystal form has better gold content than pyrite with better crystal form.Pyrite with pentagonal dodecahedron has better gold than pyrite with cube shape.The dark yellow pyrite has better gold than the bright yellow pyrite.The pyrite structure of fine-grained structure has better gold than that of coarse-grained pyrite.Pyrite substitution for isomorphism has better gold than no substitute for isomorphism.关键词
