Mainly coarse grained gold, along with pyrite, pyrrhotite, arsenopyrite, and minor base metal sulfides, occur in networks of quartz veinlets, brecciated wallrock, and disseminated in altered wallrock.
大部分粗粒金主要赋存在网格状石英细脉和角砾状围岩中的黄铁矿、磁黄铁矿、毒砂和少量贱金属硫化物中和以分散状分布在蚀变围岩中。
The toughness of weld metal is the highest while the coarse grained region in the HAZ is the lowest because of welding thermal cycle and formation of brittle microstructure.
试验钢由针状铁素体和少量块状铁素体组成，焊缝为典型的针状铁素体组织，焊接热影响区粗晶区以粒状贝氏体为主。
