从十九世纪起,魁北克省东部的舍布鲁克地区就一直吸引着地质学家的极大兴趣。该地区的主要金属矿床,阿尔贝、尤斯蒂斯、卡佩尔和萨菲尔德,直到1953年,都在断断续续地开采着,萨菲尔德矿山在1953年停止作业。近年来,对该地区,特别是老萨菲尔德矿山附近地区,进行了频繁的找矿活动。尽管如此,不同的岩石单元,特别是富含铁氧化物和锰氧化物的单元,与矿体的关系仍然未能确定。在萨菲尔德、霍华德、金和银星矿山,富含锰和铁的岩石(可能是喷出岩)与矿体接触,而在阿尔贝和卡佩尔矿山,富锰和富铁岩石与矿体很接近(倘若不是与矿体直接接触的话)。所做的研究工作的目的是拟对这些含铁和锰的岩石进行岩相学和化学鉴定,以确定这些岩石与该地区的块状硫化物矿床之间是否存在有相关关系,这些关系对寻找新的
From the nineteenth century onwards, the Sherbrooke region of eastern Québec has drawn great interest from geologists. The main metal deposits in the area, Albert, Eustis, Capel and Saffield, were intermittently mined until 1953, leaving the Saffield mine in 1953. In recent years, frequent prospecting activities have been conducted in the area, especially in the area near the old Suffield mine. In spite of this, the relationship between different rock units, especially those rich in iron oxides and manganese oxides, is not yet confirmed. At the Suffolk, Howard, Gold and Silver Star mines, rocks rich in manganese and iron (probably spewed rocks) are in contact with the ore body, whereas at the Albert and Capel mines, manganese-rich and iron-rich rocks and ore bodies Very close (if not in direct contact with the ore body). The purpose of the research work is to conduct petrographic and chemical characterization of these iron and manganese-bearing rocks to determine whether there is a correlation between these rocks and massive sulphide deposits in the area, new
