IP measurements on tunnel walls of a sericite deposit—A contact method of nonpolarizable electrodes on a base rock and detection of clay minerals by normalized chargeability
IP (induced polarization) nonpolarizable electrode tunnel wall resistivity
2009/3/5
The development of the IP (induced polarization) measurement technique used inside a tunnel is required in order to estimate the subsurface resistivity and chargeability structures with high precision...
Experimental Transformation of 2M Sericite into a Rectorite-Type Mixed-Layer Mineral by Treatment with Various Salts. II. Experiments Using a Magnetic Stirrer and a Centrifuge
Interlayer Interstratified Potassium Rectorite Sericite
2012/2/10
Dehydroxylated sericites were stirred in the various salt solutions, or washed several times with various salt solutions using a centrifuge. By these treatments a sericite of the 2M type was easily tr...
Experimental Transformation of 2M Sericite into a Rectorite-Type Mixed-Layer Mineral by Treatment with Various Salts
Rectorite-Type Mixed-Layer Mineral Treatment Various Salts
2012/2/13
Some dehydroxylated sericites were boiled with solutions of various salts. A rectorite-like regular mixed-layer was formed when 2M sericite was treated with solution containing salts such as NaNO3, Na...
Transformation of Sericite into an Interstratified Mineral
Transformation Sericite Interstratified Mineral
2012/2/20
Sericite was K-depleted with molten LiNO3. The sample was changed into an interstratified structure in the presence of a small amount of LiNO3 after prolonged treatment, and in the presence of a consi...
