I am working on a research project to evaluate weathering intensity in some marsh soils by using minerals indicaters, so I need equation or formula to apply on my x ray data.
instead of writing a lengthy text I attach a sequence of minerals based upon which you can easily decide in which level of sugergene alteration you are.
DILL, H.G. (2020) A geological and mineralogical review of clay mineral deposits and phyllosilicate ore guides in Central Europe - A function of geodynamics and climate change.- Ore Geology Reviews 119 (on-line)
DILL, H.G. (2017a) Residual clay deposits on basement rocks: The impact of climate and the geological setting on supergene argillitization in the Bohemian Massif (Central Europe) and across the globe.- Earth Sciences Reviews 165: 1-58.
DILL, H.G. (2017b) An overview of the pegmatitic landscape from the pole to the equator – Applied geomorphology and ore guides.- Ore Geology Reviews 91: 795 – 823.
This sequence is explained in more detail in Dill (2017a). You will find more information also on more exotic minerals in ore deposits in the above papers Dill (2017b, 2020).
DILL, H.G., WEBER, B. and BOTZ, R. (2013) Metalliferous duricrusts (“orecretes”) - markers of weathering: A mineralogical and climatic-geomorphological approach to supergene Pb-Zn- Cu-Sb-P mineralization on different parent materials.- Neues Jahrbuch für Mineralogie Abhandlungen, 190: 123-195.
Dill et al. (2013) also provides you with thermodynamic calculations.
All paper are available for download on the RG server.
These papers are written from a mineralogical , geomrrphological and pedological point of view.
