| 英文摘要 | Electrical conductivity is measured for dry and saturated with 1M NaCl eclogites at various pressures and temperatures, which are prevalent in the mid and lower crust. The results show that the electrical conductivity of dry eclogites parallel to the lineation is higher than that perpendicular to the lineation, however the activation energies are similar along both directions. The conductivity of dry eclogites at conditions of the mid and lower crust is several orders of magnitude lower than that of average highly conductive layers (HCL). At room temperature, the dependence of the conductivity of saturated eclogites on pressure is different in directions parallel and perpendicular to the lineation. The conductivity of saturated eclogites at mid and lower crust conditions is in the range of values of average HCL. However, the electrical conductivity of eclogites, regardless dry or satruated, is even much lower than that of Dabieshan HCL at the depths between 20 and 50km beneath the surface, and therefore is not used to explain the genesis of this HCL. Thus eclogites are not the main rock type at such depths in Dabieshan area. |
