| | An accurate and highly sensitive speetrographic method for the determination of ultratrace gold was reported. This method was based on the use of a small activated carbon column for collecting gold. The quantity of the activated carbon used in the column was so arranged that the weight of the ash formed after ignition was about 0.1-O.lSmg. The ash was then subjected to spectro-graphic determination. This method can be applied in the concentration range of 0.1-3000 ppb of gold. The coeffici... | | 本法改用新型活性炭吸附柱减小灰分量,以石墨粉作活性炭灰分的分散剂,采用快速曝光,于国产一米平面光栅摄谱仪上获得测金的绝对灵敏度为1—2毫微克,为测定地质试样中低于地壳丰度量的金提供了一个精确、快速的分析方法。线性范围为2毫微克—30微克,测定o.x-xppb样品的变动系数20—27%,可用以分析含金0.1—3000ppb的试样。 | | 文摘来源 | | The law of progression presented by "the diwa theory" manipulats the formation and distribution of gold deposits. The tectonic stage of "mobile regions" is favourable for gold mineralization. The second stage inherits and remoulds the gold mineralization or ore-bearing beds of the former stage. In the end, a new deposit takes shape. The form ation of an economic gold deposit ordinarily is polygenetic and comp lex. Above all, diwa regions possess favourable conditions for this metallo... | | 地壳演化动定递进的规律控制着金矿的形成与分布,大地构造发展阶段处于活动区期是金成矿的有利时期。后一个阶段继承并改造前一个阶段的金矿床或矿源层,使形成新的金矿。一个有价值的金矿往往是多因复成的,地洼区最具备这种条件,是找金的有利地区。 山西金的成矿期主要有两个:一个是在前震旦纪结晶基底层中(晚太古代——早元古代):另一个是地洼构造层中(中——新生代)。在空间上主要分布在地洼区四级单位——地穹或地穹与地洼的交接带,或地洼中的更次一级正单位中。据分析,阜平亚构造层为一活动区型,可能存在绿岩带、这个带富产金矿。 | | 文摘来源 | | An accurate and highly sensitive spectrographic method for the determination of ultratrace gold was reported. This method was based on the use of a small activated carbon column for collecting gold. The quantity of the activated carbon used in the column was so arranged that the weight of the ash formed after ignition was about 0.1—0.15mg. The ash was then subjected to spectrographic determination. This method can be applied in the concentration range of 0.1—3000 ppb of gold.
