摘　　要：土城子熔剂用石灰岩矿赋存于震旦系甘井子组二段,为生物化学沉积矿床,沿走向延伸稳定,厚度变化均匀。本文总结了土城子石灰岩矿体地质、矿石质量等特征,分析探讨了矿床成因,为大连地区甘井子组内寻找同类型矿床提供借鉴。Tuchengzi flux limestone deposit,which occurs in the second member of the Sinian Ganjingzi formation,is a biochemical sedimentary deposit with stable extension along the strike and uniform thickness change.This paper summarizes the geological and ore quality characteristics of the Tuchengzi limestone ore body,analyzes and discusses the genesis of the deposit,and provides a reference for searching for the same type of deposit in the Ganjingzi formation in Dalian area.
