SEDITOOLS

SEDITOOLS is a collection of simple applications to convert or calculate some things as used in sedimentology.

Currently six tools are available:

• A Geological Time Scale - as published in Harland et al. 1982, Harland et al. 1989, as well as Berggren et al. 1995, Gradstein et al. 1995 (complete references included). You can change between time scaled and non-time scaled view. Biostratigraphical data and eustatic curves are in preparation.
• A Stoke's sinking time auto-calculation - you can vary water temperature, specific gravity, settling hight, grain size and the settling time.
• A centrifuge sinking time auto-calculation - you can vary centrifuge dimensions, rounds per minute, water temperature, specific gravity, and grain size.
• A 2Theta - d-value (Angstroem) - auto-conversion - by a given wavelength. Kalpha, Kalpha1, Kalpha2, and Kbeta values of Mo, Cu, Co, Fe, and Cr already exist. You can vary angle and d-value, the converter changes the counterpart automatically.
• A (simple) Time-Temperature-Index calculation (Lopatin method) - as published by Waples, D.W. (1980) Time and Temperature in Petroleum Formation: Application of Lopatin's method to petroleum exploration. A.A.P.G., Bull., 64: 916-926, Tulsa. You can give in up to 24 strata units (you need name, thickness and base age), at that time the TTI is to calculate, a (constant) geothermal gradient, the surface temperature und a R-factor (2 is standard). The TTI's of each unit and the resulted burial time and temperature, the entire TTI, and the empirically calculated random vitrinite reflectance (Rr%) is automatically shown. The maximum TTI is 750.000.
• A simple Log Generator - conctruct one-page profile logs on the base of tab-formated TEXT spreadsheets loaded or pasted into SediTools.
