  2. Goldich dissolution series - Wikipedia

    en.wikipedia.org/wiki/Goldich_dissolution_series

    This order is controlled by the temperature of the melt and its composition. Because earlier crystallizing minerals are more stable at higher temperatures and pressures, these weather the fastest under surface conditions. Saponite is a common weathering product of ultramafic and mafic rocks.

  3. List of minerals - Wikipedia

    en.wikipedia.org/wiki/List_of_minerals

    This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species .

    en.wikipedia.org/wiki/List_of_minerals...

    The merging of the 'ARD List' (approved, revalidated and discredited) with the 'GQN List' resulted in the first 'IMA/CNMNC List of Mineral Names'. The 2007 draft of the 'IMA/CNMNC List of Mineral Names' was a courtesy of the Materials Data, Inc. (MDI), its 2009 review had important modifications.

  5. Mineral - Wikipedia

    en.wikipedia.org/wiki/Mineral

    Eight elements account for most of the key components of minerals, due to their abundance in the crust. These eight elements, summing to over 98% of the crust by weight, are, in order of decreasing abundance: oxygen, silicon, aluminium, iron, magnesium, calcium, sodium and potassium. Oxygen and silicon are by far the two most important ...

  6. Mineral redox buffer - Wikipedia

    en.wikipedia.org/wiki/Mineral_redox_buffer

    These redox buffers are listed here in order of decreasing oxygen fugacity at a given temperature—in other words, from more oxidizing to more reducing conditions in the plotted temperature range. As long as all the pure minerals (or compounds) are present in a buffer assemblage, the oxidizing conditions are fixed on the curve for that buffer.

  7. Pressure-temperature-time path - Wikipedia

    en.wikipedia.org/wiki/Pressure-temperature-time_path

    Due to incomplete replacement of the earlier formed minerals under changing P-T conditions, [16] minerals formed at various P-T environments can be found in the same rock specimen. [ 16 ] [ 1 ] As different minerals have different optical characteristics and textures, determination of the mineral compositions in metamorphic rocks is made possible.

  8. Geothermobarometry - Wikipedia

    en.wikipedia.org/wiki/Geothermobarometry

    Geothermobarometry relies upon understanding the temperature and pressure of the formation of minerals within rocks. [1] There are several methods of measuring the temperature or pressure of mineral formation or re-equilibration relying for example on chemical equilibrium between minerals [1] [2] [3] or by measuring the chemical composition [4] [5] and/or the crystal-chemical state of order [6 ...

  9. Partial melting - Wikipedia

    en.wikipedia.org/wiki/Partial_melting

    Partial melting is the phenomenon that occurs when a rock is subjected to temperatures high enough to cause certain minerals to melt, but not all of them. Partial melting is an important part of the formation of all igneous rocks and some metamorphic rocks (e.g., migmatites), as evidenced by a multitude of geochemical, geophysical and petrological studies.
