  3. Compatibility diagram - Wikipedia

    en.wikipedia.org/wiki/Compatibility_diagram

    The AKF diagram is intended for rocks containing excess aluminium and silica. Its components are: A = Al 2 O 3 - (CaO + Na 2 O + K 2 O) K = K 2 O F = FeO + MgO + MnO. This diagram is less useful, because magnesium does not freely substitute for ferrous iron in many metamorphic minerals important in aluminium-rich rock.

    The free electrons thus released flow to the anode, while the cations thus formed are accelerated by the electric field and flow towards the cathode. The ions typically cover only a very short distance before colliding with neutral gas atoms, which give the ions their electrons.

    Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.

    Krypton is highly volatile and does not stay in solution in near-surface water, but 81 Kr has been used for dating old (50,000–800,000 years) groundwater. [25] 85 Kr is an inert radioactive noble gas with a half-life of 10.76 years. It is produced by the fission of uranium and plutonium, such as in nuclear bomb testing and nuclear reactors.

    Krypton-81 is useful in determining how old the water beneath the ground is. [10] Radioactive krypton-81 is the product of spallation reactions with cosmic rays striking gases present in the Earth atmosphere, along with the six stable or nearly stable krypton isotopes. [11]
