| 摘 要： | 孟家屯地处华北陆块、鲁西隆起、鲁中隆起区、东平-蒙山断隆、蒙山凸起的北侧,属片岩型石榴子石矿床。含矿岩石(矿化体)赋存于新太古代孟家屯岩组一段石榴石英岩中。矿区内共圈定石榴子石矿层3个,矿层长150～490m,厚1.67～19.40m,矿层单样品石榴子石含量一般11.33%～29.85%,平均品位17.86%。矿床矿石矿物单一为石榴子石。矿层赋存于孟家屯岩组一段中,矿石呈粉红色,氧化后呈褐红色,为其重要找矿标志。

| Abstract: | Mengjiatun is located in northern China landmass, Luxi uplift, Luzhong uplift and north part of Dongping Mengshan uplift. It belongs to schist type garnet deposit. Orebearing rocks ( ore bodies) occur in garnet quartzite in the first section of Neoarchean Mengjiatun rock group. In the mining area, 3 garnet ore strata have been circled. The length is 150 ~490m with the thickness of 1.67~19.40m. General content of garnet in a single sample is 11.33% ~ 29.85%, and average grade is 17.86%. Ore minerals are garnet in general. Ore bodieds occur in the first section of Mengjiatun rock group. Ore bodies are pink, while they are red brown after oxidation. Thus, it is an important criteria for ore prospecting. |
