中文摘要:
      新立庄铁矿床位于山东省淄博市,处于金岭短轴背斜的北东倾伏端,是一个产于中酸性侵入岩和碳酸盐岩接触带附近的接触交代型铁矿床。新立庄一带是山东著名的矽卡岩型铁矿产区“金岭铁矿区”的一部分,具有较好的找矿远景。文章深入研究了矿床地质特征和矿体地质特征,分析了成矿物质的来源和运移方式,阐述了成矿物质的沉淀和富集过程,综合分析了成矿条件;提出矿床成因属于接触交代矽卡岩型铁矿床的观点,燕山晚期是矿床的主要成矿期,矿床主要形成于中酸性侵入岩与碳酸盐岩接触带附近;矿体围岩蚀变十分强烈,其中矽卡岩化是重要的找矿标志;并初步建立了该矿床的成矿模式。
英文摘要:
      Xinlizhuang iron deposit is located in Zibo City, Shandong Province, in the North East plunge end of Jinling fractional anticline. It is a contact-metasomatic type iron deposit which is near the contact zones between intermediate - acid intrusive rocks and carbonate rocks. Xinlizhuang area is a part of “Jinling iron ore zone” locating in the famous skarn-type iron ore region of Shandong,and it has a good prospecting potential. This paper presents a thorough study on geological characteristics of the deposit and ore - body:analyzed the source and migration mode of the ore-forming materials, elaborated the sediments and minerals enrichment process of the ore-forming materials, and made a comprehensive analysis of ore-forming conditions.Some points of view can be concluded on the basis of those work :ore deposit origin is contact-metasomatic skarn-type iron deposit, the Late Yanshanian is main metallogenic period of this deposit, which emerges near the contact zones between intermediate-acid intrusive rocks and carbonate rocks; Ore wall rock alterations are very strong, among which skarnization is an important prospecting sign. The mineralization model of the deposit is initially established.
