The EM conductivity is deemed to be a quasi- DC conductivity. The high frequencies are required for a good signal to noise ratio as, pursuant to Faradays Law, the magnitude of the induced electromotive force in a conducting loop of material equals the magnitude of the rate of change of flux through it.EM conductivity max. measured value given: for a banded sample this is parallel to bedding where energising flux in ind. coil is normal to bedding; some banded samples have silica or silicates between pyrite layers and conductivity normal to bedding is quite low, in such cases the cited conductivity would be apparent as it is only due to the conductive part of the core.Measurement accuracy better than 1%, measurements are mesoscale, air dried state. Coil measurements made with Rhodes & Schwarz HM 8118 bridge and Fluke PM 6306 RCL meter.Sample locations: #1, 2 Arusha region Tanzania; #3, 4 Navajn, Spain; #5-9, 11-13, 15 Dos de Mayo province Peru; #10, 14 Gumeracha Sth Australia; #16, 17, 20 Elura NSW Palaeozoic; #18 Mt Lyell, Tasmania; #19, 28, 33 Kalgoorlie region Precambian greenstones Western Australia; #21, 24, 27, 29, 30, 34, 35, Mt Isa Group, Queensland; #22, 23 Woodlawn NSW Palaeozoic; #31 Porgera, Pacific Islands; #32 McArthur Basin Group, Northern Territory; #36 nodular pyrite, Hunan Province, China; total of 36 locations, all hard rock terrainsoft rock sedimentary pyrite not included in sample suite.61 PREVIEW DECEMBER 2019'
