| 摘 要： | 招平断裂金成矿带是胶西北著名的金成矿带,以前该断裂带中南段转弯处为空白区,除物探工作外,未开展任何地质勘查工作。近年来随着勘查不断深入,在留仙庄地区南北侧已知矿床的深部,累计新增金金属量180 t。2015—2016年,留仙庄矿区利用钻探和物探地质手段取得突破。笔者通过收集邻区地质资料,利用矿区内最新施工钻孔及物探资料,对区内矿体成矿规律、展布特征及招平断裂带转弯处物探特征进行全面、系统分析。研究发现,矿区南部Ⅰ-1号主矿体富集、产出规律明显,赋存岩性为黄铁绢英岩化花岗质碎裂岩,矿体侧伏角40°,富集体沿侧伏方向呈等间距分布,主矿体深部未封闭;通过可控源音频大地电磁测深推断,招平断裂带呈舒缓波状,具有铲式构造特征,与钻孔揭露构造带特征相符,推断断裂带可靠性强。CSAMT和SIP电阻率特征吻合较好,2号异常明显,物探异常可信度高。认为该区具有较好的找矿前景,对招平断裂带中南段深部探矿具有一定的指导意义。

| Abstract: | Zhaoyuan-Pingdu fault zone is the famous gold metallgenic belt in northwest of Jiaodong peninsula. It is the blank area in the middle southern segment and do not carry out any exploration work in the past. With the deep exploration in recent years, the accumulative total of new gold metal in the deep known deposits is 180 t in the south and north of liuxianzhuang region., Of . Liuxianzhuang area made a breakthrough by using drilling and geophysical prospecting geological merns during 2015-2016.In this paper, we use the latest exploration achievements to discuss the orebody characteristics and comprehensive geophysical characteristics, summarize the ore mineralization regularityand the distribution of characteristic and geophysical characteristics of south central section of the bend in zhaoyuan-Pingdu fault zone. It is believed that there is a good prospect for exploration in this region and occurrence lithology is beresitization granitic cataclasite. Orebody''s lateral is 40 degrees. Rich orebody in collective is along the side of the v direction, and it was a spacing distribution and such as deep main orebody was not closed. Zhaoyuan-Pingdu fault zone is inferred slow wave by the controlled source audio-frequency magnetotelluric sounding. It has the characteristics of shovel type structure, which is consistent with structural belt characteristics drilling revealled and infer that Zhaoyuan-Pingdu fault zone is more likely. The resistivity characteristics of CSAMT and SIP are in good agreement, and 2 abnormal is obvious. Geophysical anomalies is with high reliability. This paper has an important guiding significance for deep exploration in the middle southern segment of Zhaoyuan-Pingdu fault zone. |
