天津蓟州大火尖山矿区水泥用灰岩矿床地质特征及成因探讨
Geological characteristics and genesis of the limestone deposits for cement use in the mining area of the Dahuojian hill,Jizhou,Tianjin
摘要
Abstract
The Dahuojian hill mining area is located in the eastern wing of the Fujunshan syncline,and the ore bearing rock series is the second section of the Tieling formation,with 5 industrial mining bodies,with a large scale,and with layered and layer-like sequential output.The ore bodies have a length of 100～915m,and a thickness of 11～48.3m.The ore grade:CaO 47.91%～50.94%,MgO 1.83%～2.47%,the scale of the deposit is middle-sized with resource reserves of 5581.01×104 t confirmed by exploration.Based on the summary and analysis of the geological characteristics of the limestone ore body for cement use in the area,it is preliminarily believed that the genetic type of the deposit belongs to the marine sedimentary type.The geological characteristics of this deposit are somewhat representative in Tianjin,and the mining area is the limestone deposit for cement use with the highest exploration degree and the largest scale in Tianjin.关键词
