| 摘 要： | 通过对莱芜接触交代-热液铁矿4处矿田控矿条件（围岩和构造）、成矿因素（岩浆侵入和由此形成的岩浆岩）的综合研究，并基于对各矿田地质环境进行的分析对比，以规模最大的矿山矿田为标准（标准分100），用量化指标对诸因素进行分解，对其他3处矿田诸因素量化.结合控矿条件、成矿因素的作用关系与分析，提出莱芜接触交代-热液铁矿是多因素成矿.其成矿特征表现为：围岩的层控性、构造取决于围岩性质、岩浆侵入的决定性和矿床岩体的同一性4个方面.由此得出结论：矿床矿体形态反映岩浆岩体形态，岩浆岩体形态反映构造形态，构造形态反映围岩性质.文中指出了多因素成矿特征的找矿意义.

| Abstract: | Four ore fields of the Laiwu contact metasomatic-hydrothermal iron deposit are studied on the ore-controlling conditions(wall rock and structures) and ore-forming factors(magmatic intrusion and migmatite).The geological environment of each ore field is analyzed and compared.On this basis,the metallogenic factors of the ore fields are quantized by the standard(score 100) of Kuangshan ore field,the largest of the four.The result shows that the Laiwu iron deposit is formed by multi-factors,which involve stratabound wallrocks,structures,magmatic invasion and intrusive bodies.The characteristics of the multi-factor metallogenesis are significant for the prospecting of ore. |
