Geochemical anomaly characteristics of the soil secondary halo of Pangjiagou gold polymetallic deposit in Chengde, Hebei province Jiaojiao Chen1,a, Yingshu Li1,b, Daqing He1, Dongming Yang1 and Yike Zhang1 1Faculty of Land Resources Engineering, Kunming University of Science and Technology, Kunming, China 650093 aFirst Author: Jiaojiao Chen, E-mail: 903850162@qq.com.
Prospecting indications According to the comprehensive analysis of the ore deposit, it shows that the metallogenic geological conditions of the deposit are complex, ore-controlling structures possess a multi-phase, and the mineralization and the mineralization types are complicated.Mineralization conditions are medium temperature, low pressure and the weak alkaline environment, forming materials mainly come from porphyry, and are controlled by structure obviously.
And it is concentrated on part district, which will provide the mineralization material origin for the later period

The materials were characterised by measurements of the density hardness and microstructural analysis through optical microscopy. 1.Introduction High-speed steels (HSS) can be divided into groups: conventional and P/M HSS (manufactured by powder metallurgy routes).
Although these materials have good properties, they are more expensive than wrought HSS because of the higher cost of using the HIP route [3].
