The term "xenoliths" refers to pieces of the mantle found in this material as it progresses upward.
Тhe lunar material known as KREEP is hypothesized to be a remnant of a body of this material, whose interactions with surface water are also believed to be the source of Martian features called paterae. The formation of this material releases trapped argon, resulting in the resetting of the potassium-argon dating clock. This material is categorized into three main series, characterized by the presence of tholeiites, andesite, and alkali basalt. This material represents a partial melt of the basalt source region. The term "xenoliths" refers to pieces of the mantle found in this material as it progresses upward. Manifesting itself as lava when expelled from volcanoes and cooling to form igneous rocks, for 10 points, identify this material formed by the melting of rock underneath the surface of the earth.
