Abstract On the basis of geologic survey,the paper studied the status and the composition of gold and silver minerals of Chen’er
gold deposit of by means of electron microprobe analysis (EPMA). The results show that the amount of Au element decreases while
the amount of Ag element increases from core to rim in the early period electrum. It is the first time to discover hessite and matildite in
Chener gold deposit. There was no report about the hessite and matildite in the others’work. The hessite is wrapped in matildite.
Because Te,Bi and Au have similar geochemical characteristics and close relations,so we can take the hessite and matildite as the
mark of the ore searching.
Keywords Chen’er gold deposit;EPMA;occurrence;containing gold and silver minerals

作品名称:小花;作品简介:拟南芥花;作品描述:拟南芥花。
拍摄仪器:冷冻扫描电子显微镜 Hitachi S-3000N&Quorum PP3000T。
拟南芥又名鼠耳芥、阿拉伯芥,拉丁文名为 Arabidopsis thaliala (L.)Heynh,为十字花科植物,具有生育
期短、植株个体小及在高等植物中具有最少基因组物种等特点,长期以来作为分子生物学和传统遗传学研究
的模式实验材料。图片拟南芥《小花》处理方法为:先将样品经液氮雪泥速冻,经低温镀膜后在 - 130℃状态
下电镜观察,最后将电镜得到的灰度图再经后期伪彩加工而成。
