Geological Characteristics and Exploration Direction of the Fanzhuang Graphite Deposit in the Southern Margin of the North China Block
摘要
Abstract
The graphite mineralization belt on the southern edge of the North China Block is the main enriched area of large scale graphite deposits in Henan Province,and it is necessary to dissect and analyze its typical deposits.The Fanzhuang graphite deposit is a typical medium-sized graphite deposit in the area,and the controlling factors are mainly the composition of the original rock material and metamorphic processes.The original rock has been restored to sedimentary rock,with a small amount of calcareous sediment and basic volcanic material.The carbonaceous component comes from the original sedimentation of the original rock itself,and the organic carbon left by organisms is the main source of graphite formation;The intensity of metamorphism is moderate.The formation of mineral deposits is due to metamorphic graphite deposits in regional sediments.The main indicators for mineral exploration are stratigraphic indicators and mineral indicators.By summarizing and analyzing the ore-forming geological processes of this typical deposit,it is believed that there is a good prospect for peripheral exploration in the southern and eastern parts of the mining area.关键词
