We examine a database containing the results of Ar/Ar step-heating experiments performed on 194 basement K-feldspars to recover thermal history information. Qualitative examination of Ar/Ar systematics reveals that about half of the K-feldspars examined are sufficiently well behaved to be suitable for thermal history analysis. Correlation algorithms are developed to quantitatively assess the de...

We have constructed a regular binary thermal lattice gas model in which the thermal diffusion and mass diffusion are coupled and form two nonpropagating diffusive modes. The power spectrum is shown to be similar in structure as for the one in real fluids, in which the central peak becomes a combination of coupled entropy and concentration contributions. Our theoretical findings for the power sp...
