在对萨多—乌纳尔斯克矿区和菲阿格当斯克矿区所进行的地球化学研究表明。汞是花岗岩或砂页岩中多金属矿石的主要指示元素之一。因此,下面就要对原生汞晕和外生汞晕的岩石地球化学的特点进行研究。地区的地质构造为由下古生界的结晶片岩、中生界的花岗岩和侏罗系火山沉积物组成的岩石综合体。地区的主要构造单元是萨多—乌纳尔斯克背斜,在背斜中分布着众所周知的多金属矿床。背斜核部出露着古生界的花岗岩和结品片岩。其翼部由下侏罗统的火山沉积物组成。背斜被各种纵、横的断层群所破坏,使之具有断块的褶皱构造。
Geochemical studies conducted at the Sado-Un Naalsk mine and the Fige Dysk mine show. Mercury is one of the major indicator elements for polymetallic ores in granite or sand shale. Therefore, we will examine the geochemical characteristics of primary mercury halo and extrinsic mercury halo. The geology of the area is composed of rock assemblages composed of Lower Paleozoic crystalline schist, Mesozoic granitic and Jurassic volcanic sediments. The main tectonic unit in the area is the Sado-Uarnarsk anticline, with well-known polymetallic deposits distributed in the anticline. The anticline core exposed the Paleozoic granite and nacreous schist. Its wings consist of Lower Jurassic volcanic sediments. Anticlines are destroyed by a variety of vertical and horizontal fault groups, so that they have fault fold structure.
