摘　　要：河南南召五峰顶饰面用大理岩矿床位于东秦岭造山带,下古生界二郎坪群大庙组大理岩为其赋矿母岩。矿区内圈定饰面用大理岩矿体长约950m,厚29.35~130.76m,矿石类型为浅灰红色条纹条带状中细粒石英大理岩,探获饰面用大理岩矿石量960.07×10^(4)m^(3),荒料量336.80×10^(4)m^(3)。本文分析研究了矿石物理性能与加工技术性能,对矿床综合利用部分用于生产建筑石料与重质碳酸钙的可能性进行了探讨。该矿床的勘查与研究对今后在东秦岭造山带二郎坪群大庙组寻找同类型矿床具有重要的借鉴意义。The marble deposit for top facing of Wufeng in Nanzhao, Henan is located in the eastern Qinling orogenic belt. The lower Paleozoic Erlangping group Damiao formation marble is its ore-bearing parent rock. In the mining area, one marble ore is used to delineate the decorative surface, and the orebody is about 950 m long and 29.35 ~ 130.76 m thick. Ore type is light gray red striped medium fine quartz marble. The amount of marble ore used for surface decoration is 960.07 ×10^(4)m^(3), and the amount of waste material is 336.80 ×10^(4)m^(3). The physical properties and processing technology properties of ore were analyzed and studied.The possibility of comprehensive utilization of ore deposits for the production of construction stone and calcite ore is discussed.The exploration and research of this deposit have important reference significance for searching for the same type of deposits in the Damiao formation of Erlangping group in the Eastern Qinling orogenic belt.
