THERMAL PROPERTIES OF ROCKS - USGS

2010-11-6  These plots are from tables of Robie and Waldbaum (1968). The specific heat of a rock is easily calculated from values of the minerals in its mode (fig. 43 and discussion); this approach is unique, as the usual calculation is from oxides from chemical analyses. Values of specific heat for a rock are useful for many other purposes than heat

2013-3-25  This could be explain by density effects that would drive the saline tracer downwards and heat upwards, while in addition, heat transfer is much more sensitive to fracture-matrix exchanges compared to solute transfer. Flow channeling may also be a factor since it may reduce the fracture-matrix exchange area [e.g., Neuville et al., 2010]. In the ...
