a detailed synthesis of ore-forming setting, ore geology, and metallogenic regularities of ten Cu polymetallic deposits in the Yunnan province [98]. Furthermore, the polygenetic characteristics of Cu... in the Tianmashan gold deposit were summarized. The ore-forming experienced the hot-water sedimentary mineralization in Carboniferous and magmatic-hydrothermal mineralization in Yanshanian, which were the keys......
, is governed by the interactions between EM waves and rocks, which can be characterized by the dielectric properties of rock forming materials and the electric field intensity. The concentration of energy... temperature and frequency dependent. Table 6 summarizes the dielectric properties of the most common rock-forming minerals. It shows that the silicates and carbonates have low loss factors, while......
