Measurement of Dried Seafloor Massive Sulfides

We carried out spectral-induced polarization (SIP) measurements on a set of dried seafloor massive sulfide samples and compared the results with those obtained same fully saturated NaCl solution. find that conductivity polarizability are generally high for both samples, i.e., exhibiting phase shifts in order 100 s mrad imaginary conductivities up to 1 S/m. Depending particular sample, polarizabilities remain as or slightly reduced. The fact cannot be destroyed by drying significant observations because most existing theories explain mineralized rock assume pore space filled an electrolyte. also found often-used agar gel is unsuitable coupling electrodes it releases water into sample. Coupling plasticine feasible alternative significantly less fluid absorbed sample when incorporated holder.
