Q

a description of the spatial continuity of the data. The experimental variogram is a discrete function calculated using a measure of variability between pairs of points at various distances. The exact measure used depends on the variogram type selected o display the variability between data points as a function of distance. An example of an idealized variogram is shown below. You might say that along this orientation, closely-spaced data points show a low degree of variability while distant points show a higher degree of variability.

pge or platinum group of elements

A

consist of platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), osmium (Os) and iridium (Ir), and always occur together in various types of mineral deposits, typically with variable grades of Ni, Cu, Co and Au. Some mine producers are PGE-dominant whilst others are Ni-dominant. excellent catalysts for many manufacturing processes. For instance, in the commercial production of nitric acid for nitrogen fertilizers, ammonium gas is oxidized by high pressure air over a platinum-rhodium catalyst

Q

concerned with the structures formed by, and the tectonic processes associated with, the stretching of a planetary body’s crust or lithosphere. he change in the cross-sectional area along the flow path that introduces the extensional type of deformation. Fluid elements are elongated or stretched upon entering the contraction. region of the earth’s crust or lithosphere that is spreading apart due to tectonic forces acting on the surrounding areas. Back-arc basins are regions of extension behind subduction zones and are often locations where volcanoes form. fault caused by stretching of the Earth’s crust. Stretching reduces the thickness and horizontally extends portions of the crust and/or lithosphere. In most cases such a fault is also a normal fault, but may create a shallower dip usually associated with a thrust fault.
