一、序言山东莱芜铁矿是大冶式接触交代生成的磁铁矿床。矿休产状极不规则,单个矿体储量从几十吨到几千万吨不等,含铁品位平均在50%以上,对发展钢铁工业具有重要价值。对此矿区从头至尾曾进行了较为详细的磁力普查勘探,并且取得了较为满意的地质效 I. Preface The Laiwu iron ore in Shandong Province is a magnetite deposit generated by Daye-type contact. Very irregular off-peak ore, ore reserves of a single ore from tens of tons to tens of millions of tons, with an average iron content of 50% or more, the development of the steel industry has important value. This mine has been conducted from start to finish a more detailed magnetic survey, and achieved satisfactory geological effects
