甘肃省岷县寨上地区古风化壳形成与成矿作用初探

摘要

Discussions and researches on the formation mechanisms and the evolutionary process of the archaistic weathering crust in the Zhaishang area indicated that an archaistic weathering crust occurs under the Tertiary system and the outcrops of gassany gold ore bodies No. 16, 29 and 23 in the archaistic weathering crust should be of weathering crust gold deposit （lateritoid gold ore） .%文中探讨了寨上地区古风化壳形成机理和演化过程，认为在寨上矿区第三系地层以下存在古风化壳，寨上矿区王足路一带16、29、23号矿体头部的风化壳内的氧化铁帽型金矿为风化壳型金矿床（类红土型金矿）。
