Most of the magma which forms igneous rocks is generated within the upper parts of the mantle at temperatures estimated between 600 to 1600 °C.
Over 700 types of igneous rocks have been described, most of them
Lava beds supply bacteria with iron straight from the Earth's mantle, but only newly formed igneous rocks have high enough levels of unoxidized iron.
Chapman and his colleagues reached such a conclusion after analyzing the chemistry of igneous rocks to determine how thick Earth's crust was in the past
drilling in the Cooper and Eromanga basins turned up the first evidence of igneous rocks- rocks formed by cooled magma- dating to the Jurassic period, around 199.6 million to 145.5 million years ago.
Igneous rocks form from the cooling of magma or lava and compose much of
Chapman and his colleagues analyzed the chemistry of igneous rocks to determine how thick Earth's crust was in the past and then related the thickness to elevation.
Although pure forsterite does not occur in igneous rocks, dunite often contains olivine with forsterite contents at least as Mg-rich as Fo92(92% forsterite- 8% fayalite);
above 1200 °C(liquidus) and near or below 1000 °C(solidus); these values are higher than those of other common igneous rocks.
Igneous rocks(derived from the Latin word for fire,"ignis") can have very different mineral backgrounds,
The NE block is a part of the South China plate, in which strata and igneous rocks have been found dating from the Early Paleozoic to the Quaternary.
above 1200 °C(liquidus) and near or below 1000 °C(solidus); these values are higher than those of other common igneous rocks.
On that basis, rocks are divided into three classes reflecting three environments: igneous rocks come from a hot melt, sedimentary rocks from accumulation
while water from glaciers or flowing through igneous rocks is much softer.
Relative to most common igneous rocks, basalt compositions are rich in MgO and CaO and low in SiO2
form much of the continental crust.[5] Over 700 types of igneous rocks have been described, most of them

Stable isotope studies of oxygen and hydrogen in igneous rocks indicate that the oxygen-18, δ18O, content is approximately
understand metamorphic processes and the conditions of crystallization of igneous rocks.[33] This work can also help to explain processes that occur within the Earth, such as subduction and magma chamber evolution.
