Gejiu tin ore deposit is a famous tin-polymetallic in the world because of its enormous metal reserves. Besides tin, there are copper, lead, zinc, silver, iron, sulphur, tungsten, bismuth, indium and rare earth elements. It was believed that mainly skarn-type deposit, stratiform basalt-type copper orefield. The distributed Lutangba, Malage Huangmaoshan, which hosted by carbonate rocks formation Middle Triassic Series. 40Ar-39Ar dating cassiterite from sratiform Lutangba yields plateau age...
With the development of 5G technology, accurate measurement complex permittivity a printed circuit board (PCB) in wide frequency range is crucial for design high-frequency circuits. In this paper, microwave device and method based on double-sided parallel-strip line (DSPSL) resonator have been developed to measure typical PCBs vertical direction. The includes DSPSL resonator, coupling probe, pressure monitor, Farran C4209 vector network analyzer (100 K 9 GHz), FEV-10-PR-0006 multiplier...
According to the analysis of geological characteristics and Elemental correlation charac –teristics, Threshold R-factor leading results geochemistry Kanmashan Pb-Zn polymetallic deposit which is located in Lancang county Yunnan province, discovered southern arc Chong mountain-lincang-menghai mountain, alonging contact strip Lincang granitoid batholith proterozoic group LanCang, metallogenic conditions near fracture relatively ideal, can be used as a further work area.
