苏联东哈萨克斯坦卡尔宾地区地球物理调查证明,自然电场影响到金矿化的范围。这一电场是由天然源电池形成的。卡尔宾内生金矿床按矿物组合和成矿条件分为三种类型:金—硫化物型,金—石英—硫化物型和金—石英—低硫化物型。矿床往往位于砂页岩内,岩浆岩内次之。金矿赋存于含炭岩石发育地带。卡尔宾矿床和矿化赋存于自然电场异常边缘带,后者延伸数公里,宽0.2～6.5公里,强度在200～600毫伏范围内变化。 图1a表示的是金—石英—低硫化物型,矿床与自然电场异常的相对位置。此矿床
Geophysical surveys in the Karbin area, eastern Kazakhstan, in the Soviet Union, have demonstrated that natural electric fields affect the extent of gold mineralization. This electric field is formed by a natural source cell. The Carbin Endo gold deposit is classified into three types according to the mineral assemblage and mineralization conditions: gold-sulfide type, gold-quartz-sulfide type and gold-quartz-low sulfide type. Deposits are often located in sand shale, magmatic rock in the second. Gold deposits occur in carboniferous rock development zone. Carbin deposits and mineralization occur in the anomalous edge of the natural electric field, which extends several kilometers wide and 0.2 to 6.5 kilometers wide and varies in intensity from 200 to 600 millivolts. Figure 1a shows the gold-quartz-low sulfide type and the relative position of the deposit to the natural electric field. This deposit
