大庙式铁矿的成矿和找矿远景有两个方面,其一是在大庙岩体的内部,其二是在岩体之外的尚义—平泉断裂带沿线的深部。根据岩体的地表形态呈南宽北窄的似三角形,且南部边界平直并有平行的断层,推测岩体是由主侵体和溢流体组成的直立状勾手形综合体,南面相当直立的手掌,构成主侵体,北面相当于平放的并拢五指,组成溢流体。由于南面的主侵体可以一直向下延深,具有很大深度,有充足成矿物质来源,因而具有很大的成矿和赋矿远景,是找矿的重点部位。在大庙岩体的外围,沿尚义—平泉大断裂带两侧,西起崇礼,东到平泉200多千米长的地段内,有众多基性、超基性岩体发育,其内有较多的富磁铁矿岩石,构成超贫级铁矿,这些基性、超基性岩体可能属于隐伏在深部的大型基性、超基性岩体的浅部标志,具有较大的成矿和找矿远景。
大廟式鐵礦的成礦和找礦遠景有兩箇方麵,其一是在大廟巖體的內部,其二是在巖體之外的尚義—平泉斷裂帶沿線的深部。根據巖體的地錶形態呈南寬北窄的似三角形,且南部邊界平直併有平行的斷層,推測巖體是由主侵體和溢流體組成的直立狀勾手形綜閤體,南麵相噹直立的手掌,構成主侵體,北麵相噹于平放的併攏五指,組成溢流體。由于南麵的主侵體可以一直嚮下延深,具有很大深度,有充足成礦物質來源,因而具有很大的成礦和賦礦遠景,是找礦的重點部位。在大廟巖體的外圍,沿尚義—平泉大斷裂帶兩側,西起崇禮,東到平泉200多韆米長的地段內,有衆多基性、超基性巖體髮育,其內有較多的富磁鐵礦巖石,構成超貧級鐵礦,這些基性、超基性巖體可能屬于隱伏在深部的大型基性、超基性巖體的淺部標誌,具有較大的成礦和找礦遠景。

There are two aspects about metallogenic and ore-searching prospects of the Temple style iron ore,first is internal in the Temple rock body,the second is outside of the rock along the deep of the Shangyi-Hiraizumi fault zone.According to the surface of the rock in shape north narrow south wide like triangle,and southern boundary of the straight and parallel to the fault,suggesting that the rock is composed of the main invasion body and the overflow body and an upright hook-shaped complex,the south is equivalent to the upright palm,that constitute the main invasion body;the north is equivalent to the flat close five fingers together to form the overflow body.The main invasion body of the south has been downward extension of the deep,with a great depth,and has the adequate forming material source,so the main invasion body has a lot of metallogenic and bearring ore prospects,that is the key part of the prospecting.In the periphery of the Temple rock,along both sides of the Shangyi-Hiraizumi large fault zone,west up Chongli,east to Hiraizumi more than 200 kilometers long in the area,there are a number of basic and ultrabasic rocks development,within which there are more rich magnetite rocks to constitute the super-poor grade iron ore,these basic and ultrabasic rocks may belong to the shallow mark of concealed in the large,deep basic and ultrabasic rocks,and has larger metallogenic and ore-searching prospects.
