引言以马瑟尔怀特层控铁岩为容矿围岩的金矿床,分布在安大略皮克尔湖北方约120公里的奥帕皮米斯根湖区(图1)。探区在北卡里布湖变火山—沉积地体的太古宙变沉积岩中。该地体是苏必利尔地质省萨奇戈亚省的一个部分。本文使用的资料是根据详细填图和对有限露头的采样所进行的系统地表勘查,结合钻孔岩心的采样和测井、以及西背斜带的地下勘查中所获得的。 INTRODUCTION The gold deposits hosted by the Mussel White stratabound iron rock are hosted in the Opamphipesn Lake region about 120 km north of Lake Pike, Ontario (Figure 1). The exploration area was transformed into the Archean metasedimentary sedimentary rocks in the North Cariboo Lake. The site is a part of the province of Sighigeruar province, Superior. The data used in this paper is based on detailed mapping and systematic surface surveys of the limited outcrops taken in conjunction with sampling and logging of borehole cores and subsurface exploration of the western anticline.
