magnetic susceptibility and density values of rocks from the study area (appendices 3 and 4). The mean magnetic susceptibility value for all rocks from the study area is x 10 -3 cgs, with a standard deviation of x 10 -3 cgs (appendix 3).Cited by: The current database consists of location 9, entries. The surface-based, point data include 5,, 6,, and density, magnetic susceptibility, and NRM measurements, respectively. Downhole data from drillcore have also been incorporated, yielding an additional 1, and 9, measurements of density and magnetic susceptibility, respectively. DENSITY, POROSITY AND MAGNETIC SUSCEPTIBILITY OF LUNAR ROCKS. R. J. Macke 1, W. S. Kiefer 2, D. T. Britt 1, and G. J. Consolmagno 3; 1University of Central Florida. DENSITY AND SUSCEPTIBILITY CHARACTERISATION OF MAJOR ROCK UNITS AND ROCK TYPES, MOUNT ISA INLIER JUNE I1 & I2 PROJECTS The following report compiles density and magnetic susceptibility measurements over the Mount Isa Inlier. Data is based entirely on datasets porosity, sample condition and lithological descriptions. However, rarely File Size: 2MB.

Petrophysical properties of rock samples from the Suhbaatar-Ulaanbaatar-Dalandzadgad geophysical profile in Mongolia are presented. Based on the rock classifications and tectonic units, petrophysical parameters (bulk density, magnetic susceptibility, intensity of natural remanent magnetization, and Köenigsberger ratio) of these rocks are by: 2. Rocks made up of these minerals tend to be less dense due to porosity but with increasing depth of burial compaction reduces the porosity and most of the rocks comprising the crust of the Earth have a density between and The effect of density on porosity follows a mixing law. The porosity,, is the fractional pore volume of a Size: KB. The porosity of loose sand is about 40 percent; compacting and dewatering the sand reduces the porosity to about 15 percent; the lithification of the sand into a sandstone rock by formation of cement between the sand grains reduces the porosity to about 5 percent or less. PHYSICAL PROPERTIES. Physical property measurements made during Leg provided (1) sediment properties (density, porosity, natural gamma radiation [NGR], and magnetic susceptibility) to compare with composition, diagenesis, and consolidation history and to help constrain the location of unconformities, sediment fracturing, and fluid migration and expulsion; .

Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and %. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).. There are many . Grain density is measured by helium ideal-gas pycnometry, bulk density by the glass bead method developed by [2]. Porosity is calculated directly from bulk and grain densities. We also measure magnetic susceptibility, using an SM mag-netic susceptibility meter [3]. Basalts: The low-Ti ( wt% TiO2) basalts measured here group tightly in.
