Spessartine high spessartine content tend toward a light orange hue, while almandine prevalence induces red or brownish hues. Spessartine Spessartine, sometimes mistakenly referred to as spessartite, is a nesosilicate, manganese aluminium garnet species, MnAl(SiO). The mineral spessartine should not be confused with a type of igneous rock (a lamprophyre) called spessartite. Spessartine's name is a derivative of Spessart in Bavaria, Germany, the type locality of the mineral. It occurs most often in granite pegmatite and allied rock types and in certain low-grade metamorphic phyllites. Sources include Australia, Myanmar, India, Afghanistan, Israel, Madagascar, Namibia, Nigeria, Mozambique, Tanzania and the United States. Spessartine
Type theory of a function is denoted with an arrow formula_16 from the parameter type to the function's resulting type. Thus, formula_17. Calling or "applying" a function to an argument may be written with or without parentheses, so formula_18 or formula_12. Not using parentheses is more common, because multiple argument functions can be defined using currying. There are many different set theories and many different systems of type theory, so what follows are generalizations. The term formula_20 reduces to formula_21. Since formula_21 cannot be reduced further, it is called a normal form. A system of type theory is said to be strongly
