Analysis of the Characteristics and Genesis of the Inkstone Deposit of Yishui in Baoding Area,Hebei Province
摘要
Abstract
Yishui inkstone belongs to mudstone and claystone with sand content,mainly divided into two categories:"Jade Belt Stone"and"Purple Emerald Stone".The mineral-bearing strata are the Jingeryu formation of the Qingbaikou Period and the Mantou formation of the Cambrian system.This paper studies the sedimentary environment of the protolith of Yishui inkstone by analyzing the characteristics of the ore-bearing strata,ore characteristics,and rock characteristics of the Yishui inkstone,and the analysis shows that the origin of Jade Belt Stone deposit is regional low-temperature metamorphic type,while the origin of Purple Emerald Stone inkstone deposit is controlled by sedimentary layers.The lithology of the protolith and the degree of metamorphism are the main factors controlling the formation of the inkstone.Based on this,some ore-finding clues for the inkstone mines in the area are proposed.关键词
